AI Model Fine-Tuning for Improved Performance and Accuracy

I am looking for an experienced AI/ML freelancer to fine-tune an existing AI model for a specific task. The project involves preparing and cleaning the dataset, selecting an appropriate pre-trained model, fine-tuning it, testing its performance, and improving accuracy. The freelancer should have experience with machine learning, Python, and AI model fine-tuning. Clear documentation and the final trained model are required.

Analysing Large Scale Marketing Datasets

I’m seeking a skilled data professional to support a marketing research publication. The task involves accessing and analyzing large, publicly available datasets—think Facebook or Google APIs, Kantar, World Bank data, and more. You’ll need expertise in Python or other large data analysis tools, and ideally machine learning. The ultimate goal is robust, reproducible insights into areas like influencer marketing, advertising, or brand behavior. If you can help source, analyze, and collaborate toward publication-ready output, I’d love to hear from you. Experience with large-scale marketing /consumer datasets is key. Possibility of co-authorship on the final paper exists for the right fit.

Internal Training Notes Index for Customer Support Work

When someone new starts helping me with customer support, they need to understand my way of handling messages, my templates, my tags, and my internal rules. Right now, all that information is scattered across different documents and chats, with no clear order. I want a simple index that shows where each training topic lives and how it fits together. This is a one‑off setup job with a small, fixed deliverable. You will receive: My existing training materials (notes, docs, chat exports, template links, workflow descriptions – roughly 10–20 files or sections). A short note from me describing the main topics a new helper needs to learn (for example: inbox triage, tagging system, templates, escalation rules, response‑time targets). Your work will include: Reviewing all the materials I provide and grouping them into logical training topics (for example: “Getting Started”, “Inbox Triage”, “Tags & Labels”, “Templates & Macros”, “Escalation Rules”, “Weekly Review”). Creating a simple index (Google Doc or Sheet) with: Topic name Short description of what’s covered Link or reference to the source file/section Suggested order for learning (1, 2, 3, etc.) Ensuring the index is easy to scan so a new helper can see at a glance what they need to learn and where to find it. Adding brief instructions (half a page max) on how to use the index during onboarding. Delivering: One final training notes index file (Google Doc or Google Sheet). A short instruction note (can be on the first page of the same file). This index is only for my internal use when onboarding someone to help with customer support. It will not be shown to customers or posted on any website or external platform. If you have experience creating training indexes, onboarding docs, or similar internal resources for customer service or virtual assistant work, please send a message with: A brief description of any similar onboarding or training documentation you’ve built. How you keep training materials clear and easy to follow for someone new.

AI Pricing & Valuation System

# Tender Brief – AI Pricing & Valuation System ## Project Overview We are a multi-site second-hand retail business operating a buy, sell and buyback model. We currently value products using a combination of: * eBay sold prices * CEX prices * Customer history * Our own large historical transaction database * Current stock levels * Staff experience We are looking for a software / AI development partner to build an intelligent pricing engine that integrates with our existing EPOS system. ## Objective The system should recommend the optimal price we should offer a customer for a product. It should use both our own historical data and external market data to produce a more dynamic and commercially accurate valuation. The aim is to improve: * Buying accuracy * Gross profit * Stock turn * Consistency between stores * Offer acceptance * Inventory management ## Initial System Requirements The first version should ideally: * Identify and standardise the product being valued * Analyse our historic purchase and selling data * Incorporate eBay and CEX market pricing * Predict likely resale price * Predict expected time to sale * Consider current stock and sales demand * Recommend an acquisition price * Provide a confidence score * Allow staff to override the recommendation * Record results so the system can improve over time Example output: **Recommended offer: £405** Expected resale: £550 Expected sale time: 19 days Current stock: 4 30-day sales: 27 AI confidence: 96% ## Technical Approach We expect the solution to integrate with our existing EPOS through an API. We are open to the supplier recommending the most appropriate technologies, potentially including: * Machine learning such as XGBoost or LightGBM * OpenAI or similar AI models for product identification and image analysis * External market-data integrations * Predictive pricing models * Inventory and demand modelling We do not expect a large-language model alone to determine product prices. ## Our Data We hold a substantial database including information such as: * Products * Purchase prices * Selling prices * Purchase and sale dates * Stock history * Store/location * Product condition * Customer history * Buyback history * Staff valuations * Current inventory The successful supplier will need to assess the quality and structure of this data and recommend how it should be used. ## Initial Rollout We would ideally operate the system in **shadow mode** initially. The AI would calculate its recommended price alongside our existing staff valuations without influencing the actual transaction. This would allow us to compare: * AI recommendation * Staff recommendation * Actual amount paid * Eventual selling price * Stock days * Actual profitability Only once the model has demonstrated improved performance would it be introduced into live pricing. ## Future Development The system should ideally be capable of later expanding into: * Buyback-specific pricing * Dynamic retail pricing * Automatic markdown recommendations * Store-to-store stock transfers * Inventory optimisation * Product demand forecasting ## What We Would Like From Suppliers Please provide: * Your proposed technical solution * Relevant experience * Recommended AI / machine-learning approach * How you would integrate with our EPOS * How you would use our existing data * Approach to eBay / CEX market data * Development costs * Ongoing costs * Proposed project stages * Examples of similar work We are particularly interested in suppliers with experience in retail pricing, second-hand goods, machine learning, dynamic pricing, inventory optimisation or EPOS integrations. ## Key Question As part of your proposal, please explain: **How would you prove that the AI pricing recommendations are commercially better than the decisions currently being made by our experienced staff?**

Algorithmic Developer – Provably Fair & RNG Systems

About the Project: We are seeking an experienced Developer / Machine Learning Engineer with deep expertise in Random Number Generation (RNG) algorithms and Provably Fair architectures. The goal of this project is to analyze, optimize, and potentially rebuild our current predictive/analytical model pipeline. Currently, we have an active LSTM-based model setup. We need an expert who can evaluate its architecture, improve its accuracy and efficiency, or design superior alternative models from scratch tailored to our specific data distribution and fairness requirements. Key Responsibilities: Audit and optimize the existing LSTM model pipeline for better performance and predictive accuracy. Evaluate alternative architecture options (e.g., Transformers, Markov models, or hybrid architectures) and build new models from scratch if required. Ensure all algorithmic logic strictly aligns with RNG principles and Provably Fair cryptographic standards (HMAC, SHA-256 / SHA-512 verification). Fine-tune hyperparameters, validate data pipelines, and reduce model latency. Requirements: Proven track record working with RNG (Random Number Generation) and Provably Fair frameworks in production environments. Deep experience in Time-Series Forecasting and Sequential Data Modeling using LSTM, GRU, or Attention/Transformer networks. Strong background in PyTorch or TensorFlow. Solid understanding of cryptography basics relevant to Provably Fair verification mechanisms.

Video / Cameo PP Editor Needed

Video Editor Needed – Professional E-Learning / Training Videos We are looking for an experienced video editor with e-learning, corporate training or online course experience to edit a series of 5 professional training modules. The presentations have already been professionally designed and recorded using PowerPoint Cameo. We are not looking for the slides to be recreated or redesigned. The PowerPoint presentation can be exported directly as an MP4 and used as the basis for editing. What we need We want to transform the existing presentation into a polished, engaging online learning experience. Editing will include: *Integrating the presenter naturally into the main screen rather than leaving them permanently in a small corner box. *Using different layouts where appropriate, e.g. presenter on one side with key content on the other. *Occasional highlighting/animation of important points as the presenter discusses them. *Relevant graphics, icons or simple visual elements to reinforce key topics. *Subtle movement and visual changes to maintain engagement. *Clean, professional transitions. *Ensuring the presenter/voice remains correctly synchronised with the presentation. *Professional audio treatment. *Music for the opening and closing, with smooth fades and occasional use for major transitions rather than continuous background music. We do not require every bullet point or slide to be animated. We are looking for thoughtful visual emphasis at appropriate moments throughout the training. The finished videos should feel like a professionally produced online course, not simply a PowerPoint presentation with a webcam recording in the corner. Style Clean, modern, professional and engaging. We already have the presentation design and branding, so the focus is on video editing and visual engagement, not redesigning the slides. Important There are 5 modules in total, with a tight delivery schedule. We would initially like a short sample section from Module 1 edited by 23rd September so we can agree on the visual style before it is applied across the complete series. The remaining modules need to be completed by 6 October 2026. Before submitting a proposal, please: Confirm your availability and turnaround time. Confirm when you could complete Module 1. Confirm you can complete the remaining modules by 28 September. Provide examples of e-learning, training, educational or presenter-led video editing you have previously completed. Confirm that graphics, key-point highlighting, presenter integration, audio/music editing and transitions are included in your quote. Once i receive your proposal i will provide you with the source material before committing to the project and only submit a proposal if you are confident you can deliver the required style and timeframe.

Animated App Explainer Video

## Animated App Explainer Video – Nurture UAE We are looking for a talented **motion graphics / animation designer** to create a short, professional explainer video for our childcare app, **Nurture UAE**. ### About Nurture Nurture is an app designed to help parents and nannies/caregivers stay connected throughout a child's day. Parents and caregivers can share daily care updates, communicate through the app and access tools including activities, meals & recipes, learning resources and more. ### What we want to create We would like a **60–90 second animated explainer video** demonstrating how Nurture works. The video will be narrated by our existing owl mascot, **Nuri**. Nuri should become an animated character who **flies/moves around the screen, talks to the viewer and points towards different areas of the Nurture app interface** as they are being explained. We will provide the original Nuri mascot artwork and access/screenshots/screen recordings of the app. ### Example flow The video should demonstrate: **1. Parent joins Nurture** Nuri introduces the app while the Nurture interface appears on screen. **2. Connecting a caregiver** Show how a parent creates/connects their account and invites their nanny or caregiver to join their family. Nuri flies alongside the interface and points towards the relevant buttons/actions. **3. Daily Care** Show how the nanny can record things such as: • Meals • Naps • Activities • Photos • Mood/care updates And how the parent can see these updates during their day. **4. Messaging** Demonstrate parent–caregiver messaging and Nurture's translation functionality. **5. Activities** Show the activity section and how caregivers can find age-appropriate activity ideas for the child. **6. Meals & Recipes** Briefly demonstrate the recipe/meal features available to caregivers. **7. Nanny Learning** Show the learning resources available to help caregivers build their knowledge and skills. **8. Ending** Bring Nuri back prominently on screen alongside Nurture branding and a simple CTA: **Your child's day. All in one place.** **Download Nurture UAE – available on the App Store & Google Play.** ### Style we're looking for The finished video should feel **premium, modern, friendly and professional**. Nuri should add personality and warmth, but we don't want the video to feel overly childish. The primary audience is **parents of young children in the UAE**. We would particularly like someone who can combine: • 2D character animation • Motion graphics • App/UI animation • Screen recordings • Professional transitions • Voiceover/narration syncing • Sound effects/background music Nuri's existing design and colours **must remain consistent with our supplied mascot** rather than being redesigned or replaced with a generic AI-generated owl. ### Deliverables • Final 60–90 second explainer video • Vertical **9:16 version** for Instagram/Reels/TikTok • Landscape **16:9 version** for website/YouTube • High-resolution MP4 files • Animated Nuri mascot • Background music/sound design • Subtitles/on-screen captions • Source/project files where possible We can provide the Nurture branding, mascot artwork, app screenshots/screen recordings and guidance on the features that need to be demonstrated. ### When applying Please send examples of **app explainer videos, UI animations or character animation** you've previously created. If possible, please also explain how you would approach animating our existing owl mascot alongside screen recordings of the Nurture app. We're looking for someone who can take the concept and turn it into a polished, engaging video rather than simply assembling screenshots into a slideshow.

EXECUTIVE PERSONAL ASSISTANT - Direct Person - No Agents

Flexible, adaptable, intelligent, diplomatic and ruthlessly efficient describes the person required. This opportunity is only for serious players. Your British Spoken and Written English skills must be excellent; there is no time for correcting spellings and pronunciations from other jurisdictions and dialects. You must be capable of being shown how to do something once and then doing it correctly, consistently and repeatedly without needing to be reminded, chased or shown again. You must be available to start immediately. British working hours must be covered, although working times will vary and may fall anywhere between 6.00 am and 9.00 pm. Weekend work will be required when workloads, urgent cases or major deadlines demand it. You will become the right-hand person to the Executive Director of Landlord Licensing & Defence. Things must be made to happen quickly, accurately and efficiently so that backlogs do not develop and deadlines are never missed. Fast and reliable broadband is essential, together with a backup internet connection for use if the main service fails because of a provider problem, natural disaster or any other disruption. This role is for someone who works hard, goes the extra mile, remains dependable and understands that clients and urgent work cannot simply be abandoned when pressure increases. The systems are relatively simple and straightforward, and anyone who listens carefully, follows instructions and learns quickly should be capable of providing the required support. Much of the work involves copying and pasting accurately, interpreting information, filling gaps, completing forms, preparing documents, maintaining systems and relentlessly following people up until the required result is achieved. The Executive Director does not have time to continue carrying out administration because previous assistants were inefficient, failed to learn and could not act properly upon short or incomplete instructions. There is nothing unnecessarily complicated about the administrative work, but it must be completed correctly, quickly and in exactly the required way. Excellent spoken and written English is compulsory. Perfect grammar, spelling, comprehension and attention to detail must be demonstrated in everything written and said throughout the application process. Being “nearly right” will not be good enough. Communication must always be written in the required house style, which means that there is no “I” or “we”, the client and subject matter remain central, opinions are not invented and every statement is based upon facts, evidence, the law and the reality of the work being undertaken. All clients are under immense pressure because enforcement action is being taken against them. Anxiety and distress must be handled quickly, calmly and diplomatically without promises being made that cannot be fulfilled and without deadlines being committed to unless delivery can be guaranteed. Incomplete instructions must be understood in the context of previous work so that documents and tasks can be prepared for checking without everything having to be explained from the beginning. Corrections must be understood, implemented immediately and applied to all future work without the same mistakes being repeated. This is not a comfortable role for someone who needs constant supervision, avoids responsibility, disappears when things become difficult or produces excuses instead of results. The Executive Director works fast, expects things to be done properly, does not suffer fools gladly and wants the bloody job done. If that sounds unreasonable, do not apply. If that sounds like the challenge you have been waiting for, apply now. Where you live does not matter, and applications are welcomed from anywhere in the world provided that the required working hours, availability, internet reliability and standard of English can be delivered without exception. ACTION: Send a short, entertaining story by DM explaining why an invitation to apply should be sent to you. Do not send a generic CV introduction, corporate waffle or something obviously produced by artificial intelligence. Show intelligence, personality, humour, perfect English and the ability to follow these instructions.

We are specifically looking for someone who already understands how Surrey County Council’s tendering/procurement portal and application process works and can lead and assist us through the process from start to finish.

We need someone who can review the documentation we already have, identify what can be reused or adapted for the new company, identify anything that is missing, advise us on exactly what additional policies/evidence are required, assist with the portal and application requirements, prepare strong and compliant responses and help us through to final submission. Previous direct experience with Surrey County Council is strongly preferred. Experience with UK local-authority Home-to-School transport, SEND transport or passenger transport frameworks would also be highly desirable.

I need RP voiceover of phonemes for a pronunciation app

Hi! I'm building a British English (RP) pronunciation-learning app and need a single native RP voice recorded for the app's sound library. I'm checking for standard Received Pronunciation specifically — no R sound in "rather"/"water" (non-rhotic), "bath" said with a long "ah" not a flat "a", a clear T in "water" (not "wa'er"), and the H in "have" kept in. If that sounds right, here's the job: About 380 short clips total: 88 isolated phoneme sounds (2 speeds each), 280 individual words, and 12 short phrases spoken at natural fast conversational speed Single voice throughout — one quiet room/session for consistency Delivered as WAV or M4A, 44.1kHz or higher I'll send the full word list and file-naming spec once we're ready to start recording This is for a commercial, paid app (subscription-based), not a personal project — so I need full commercial usage rights: a complete buyout of the recordings, work-for-hire, no royalties or usage caps, and no restriction on redistributing the audio inside a paid app. Please confirm upfront whether your standard rate includes that license or if a commercial buyout costs extra, so there are no surprises later. This could later lead to additional work if it were a success.
