Test build for AI coaching agent

I am looking for a developer who can build a lightweight, hosted chat application that wraps an existing system prompt around the Anthropic Claude API and gives my testers a shareable URL. This is a testing and validation build. Please read the attached detailed spec. Developer Brief: Purpose Coaching Agent — Test Build I have developed and tested a new coaching agent's system prompt and am now ready to deploy a simple hosted version so a small group of nonprofit leaders can test it and give me feedback. Requirement A lightweight, hosted chat application that wraps our existing system prompt around the Anthropic Claude API and gives testers a shareable URL. This is a testing and validation build - I want the simplest thing that works well. Scope - Build a chat web application with the following: - Clean, mobile-responsive chat interface - Calls the Anthropic API using Claude Sonnet 4.6 (model string: `claude-sonnet-4-6`) - Our system prompt (provided separately) is loaded server-side and is not visible or accessible to end users - Conversation history maintained within a session (no persistence across sessions required at this stage) - A welcome message displayed when the user first opens a conversation - Simple branding: our logo, our primary brand colour (#0F4C81 — Classic Blue), and the name "Purpose Coaching Agent" - A brief footer or note indicating this is a prototype for testing purposes - A simple passcode gate so that only people we give the passcode to can access the chat — nothing more than a single shared passcode stored as an environment variable - The ability for us to update the system prompt without redeploying the application Needs to deploy free or low-cost hosting with: - A shareable public URL - Our Anthropic API key stored securely (not in the codebase) - No account creation or login required for testers beyond the passcode above Not Needed - User authentication or individual user accounts - Conversation history saved to a database - Admin dashboard or analytics - Rate limiting or abuse prevention (access is controlled by passcode and we are sharing the link with fewer than 20 people) - RAG, document retrieval, or knowledge base integration Technology Streamlit with Streamlit Community Cloud hosting or a Next.js or Flask app deployed to Vercel or Railway would be fine. If you want to use something else, let me know why and the benefits. The system prompt should be stored in a configuration file or environment variable that I can edit directly (not hard-coded into application logic). What I’ll Provide - The full system prompt (a text document, approximately 3,000 words) - Logo file (PNG, transparent background) - Brand colour: #0F4C81 (Classic Blue) - An Anthropic API key for development and testing - Feedback and sign-off within 24 hours of deliverable Deliverables 1. Source code in a private GitHub repository (transferred to our GitHub account on completion) 2. Deployed, working application with a live URL 3. Brief setup notes: how to update the system prompt, how to change the passcode, how to redeploy if needed, where the API key is stored Timeline Completed within five working days of commissioning with actual build of one to two days. Budget Please quote a fixed price. Please include: - A fixed-price quote and estimated delivery timeline - One or two examples of similar work (a chat interface calling an LLM API, or any Anthropic/OpenAI API integration) - The framework and hosting platform you would use, and why - Confirmation that you're comfortable with the Anthropic API specifically

WordPress PHP Upgrade & Compatibility Testing

We are looking for an experienced WordPress/PHP developer to upgrade our existing WordPress website, which is running on the outdated PHP 8.0. The target is to move to a current PHP version (ideally PHP 8.5, subject to testing). Job tasks: • Create a full copy of the website on an independent staging server. • Audit and assess any compatibility issues with current theme, add-ons, plugins or custom code. • Update as required. • Upgrade PHP on the staging environment and resolve any resulting errors. • Thoroughly test the site's front end, admin area, forms and key functionality. • Final review of the site on the staging server. • Deploy website back onto live server. NOTES: Staging Server: The developer must provide their own staging/test server, with access provided to us so that we can review and approve the updated site before live deployment. The live site must remain fully active until the upgraded version is ready to be deployed. Elementor + Astra: The website is built using Elementor Pro with the Astra Pro theme. There is also strong CSS customisation. Plugins: Although most pages are straightforward brochure-style, the site contains a number of additional functional plugins which will require testing following the PHP and plugin updates. We have approximately 25 active plugins to be updated. However, we do NOT use Woo-commerce or any other shop plugin. SUMMARY: Applicants should have experience with WordPress, PHP upgrades, plugin compatibility, staging environments and live deployments.

I need someone who can create meta and google campaigns

I’m a Co-Founder of Haniesta, a luxury rug brand we launched a few months ago. We’re seeing strong traction and growing sales through Amazon and eBay, but our website sales are still relatively low. I’m looking for someone who can take ownership of our paid acquisition and help turn our website into a strong sales channel. This includes creating high-performing ad creatives, managing and optimizing Google Ads campaigns, testing different strategies, and ultimately driving profitable sales through our website. I’m less concerned about how you achieve the results and more focused on the outcome: website sales and measurable growth. You’ll have the freedom to experiment, test creatives, optimize campaigns, and suggest changes to landing pages or the overall funnel if needed. This can also become much more than a short-term role. If you consistently go beyond expectations, take ownership, and deliver strong results, there is a genuine opportunity to move into a higher-level, permanent position with Haniesta as we grow. Please apply only if you’re confident that you can start generating measurable sales within the first month. We’re looking for someone who is execution-focused and comfortable being accountable for results.

Can sketch my ideas & physically build a rough test model

I am looking for someone who can do two things: 1.⁠ ⁠Listen to my product idea and sketch it out clearly. 2.⁠ ⁠Physically build a rough basic model of it, using simple materials if possible. I do not want CAD files, 3D renders, digital images, UX design, branding, or a polished prototype. I need someone who can actually make a simple physical version so I can see whether the idea works in real life. The model does not need to look beautiful. It does not need to be factory-ready. It can be rough, basic, handmade, and made from wood, plastic, card, foam board, 3D printed parts, brackets, hinges, magnets, or whatever simple materials make sense. The important thing is that you can think practically, sketch the idea, and then build a physical proof-of-concept model yourself. I am based in London and would prefer someone I can meet in person first, but I am open to discussing options. I would prefer someone based in London and or near London. I know some designers are like "any designer who is worthwhile makes cad drawings and renders". Back 200 years ago, there were no computers, yet people made things, inventions were still created. I need an 'old school' mindset because I just purely want a person who can and does make things in their home. Also, someone who has a great understanding on how things work and when things won't work. Please quote for an hourly rate, as I would like to find someone I can meet on a regular basis for various product ideas, not just x1. Also, before any work commences I would ask you to sign a simple NDA for idea protection. Thank you. **Important note: Important clarification about CAD and digital work: I am not preventing anyone from using CAD, digital modelling, computer renders or any other tools they feel are useful in producing the physical model. Use whatever methods you need or want to use behind the scenes. However, I do not want excessive time spent perfecting polished digital renders, and I do not want to be charged for hours of digital work that I have expressly said I do not require. Any digital work should be kept to the minimum in what is genuinely needed to create the physical prototype accurately. The work I am commissioning and paying for is the physical rough prototype, not a beautiful computer render. Also as I said I am not looking for perfection I am looking for a rough physical model that won't win any awards on beauty.
