Interactive AI Experience – 3D Guide & Custom Image Gen
I am an artist developing a browser-based interactive ritual experience where a 3D speaking character guides participants through a reflective AI-driven dialogue about the future. At the end of the interaction, the system produces: • A symbolic, poetic spoken response • One AI-generated image based on the participant’s clarified vision, rendered in a custom visual style trained on my artwork This is a poetic, immersive digital art experience, not a generic chatbot or commercial tool. Deliverable: A mini website / web module that can be integrated into an existing website (for example, as a subpage or subdirectory). Scope Clarification The generated images will later be shown in a separate digital “wall” project built by another team. This job does NOT include building that wall interface. Your responsibility is to: ✔ Generate the images ✔ Store them with structured metadata ✔ Make them exportable for future integration Technical Constraints (Non-Negotiable) - • Open-source / open-weight AI models only (LLM, image generation, TTS, STT) • Self-hosted deployment on my infrastructure (Hetzner servers) • No proprietary AI APIs Core User Experience Flow - - Short conceptual intro animation - 3D character appears and speaks, introducing the ritual - User selects one of five thematic prompts - User shares a vision (text input; voice input optional bonus) - AI-guided dialogue (2–4 turns) to clarify the scenario - Final symbolic spoken response from the character - One AI-generated image created from the clarified vision - Session data saved for archive and future visual display Technical Requirements - Frontend (Mini Website) • Immersive but lightweight interface • Smooth transitions between stages • Audio playback (music + character voice) • Responsive design (desktop + mobile) • Built using React / Next.js or similar 3D Speaking Character - • WebGL / Three.js / A-Frame (or similar) • Rigged character model (provided) • Idle animation • Speaking animation synced to audio (lip sync preferred, amplitude-based acceptable for MVP) AI Dialogue System (Open-Source LLM) - • Self-hosted open-weight model • Multi-turn conversation handling • Structured prompting system • Outputs: – follow-up prompts – final poetic response – structured summary for image generation Voice System (Open-Source TTS) - • Open-source text-to-speech hosted on server • Audio drives speaking animation Custom Style Image Generation - The generated image must consistently match a custom artistic visual language based on my artwork. Prompting alone is not enough. You must implement: Preferred: LoRA training using my artwork dataset Alternative: Style adapter / reference conditioning Requirements: • One image per session • Seed reproducibility • Style strength control • Save prompt + generation parameters Backend & Storage Store for each session: • Selected prompt theme • Dialogue transcript • Final spoken response • Scenario summary • Image prompt + parameters • Generated image file • Timestamp Admin Panel Simple password-protected page to: • View sessions • Download text and images Deployment Requirements • Linux deployment on Hetzner • Docker / Docker Compose preferred • Documentation for: – setup – model downloads – environment variables – running services – updating style model Project Timeline Total duration: 2 months Skills Required • Web 3D (Three.js / A-Frame / WebGL) • Experience integrating animated 3D characters in the browser • Experience serving open-source LLMs • Diffusion model LoRA or adapter training • Backend/API development • Docker + Linux deployment How to Apply Please include: 2–3 relevant projects (AI apps, WebGL/WebXR, or interactive experiences) Proposed tech stack (frontend, backend, model serving) Which open models you would use (LLM, diffusion, TTS) and why Recommended server setup (GPU/VRAM) for acceptable performance Screening Questions How would you sync speech audio to a 3D character animation in the browser? Which open-weight LLM would you deploy and how would you serve it? How would you train and deploy a custom style LoRA for image generation? What server setup would you recommend and why?

MERN Developer
We are looking for a senior developer to help us finalise and consolidate a number of projects which are 75% complete. We expect this to be an ongoing, monthly paid role and so the budget is on that basis. We have a legacy system that, whilst functional, is outdated and needs the functionality migrating/replicating in our new environment. The work will include refactoring, adding routes and connecting multiple interfaces to complete the job. You will need to have an understanding of complex data structures to ensure that migration and CRUD functionality is accurate to serve various interactions of the project. Lastly, the platform has a companion application that is built and compiled in EXPO. This will need attaching to the new migration, rebuilding and deploying to the stores appropriately. Therefore the following experience is necessary **Key Responsibilities:** - Develop new features and enhance existing functionality for our directory website using the MERN stack (MongoDB, Express.js, React.js, Node.js, Next.js). - Utilise trunk-based development practices to ensure smooth and timely integration of code into the main branch. - Work collaboratively with other developers to resolve conflicts and merge changes efficiently. - Perform regular performance and bug-fixing tasks to ensure optimal website performance. - Write clean, maintainable, and efficient code, following best practices and industry standards. - Participate in code reviews to maintain code quality and provide constructive feedback. - Continuously improve and upgrade the software to keep up with the latest advancements in technology. **Required Skills and Experience:** - Proven experience as a MERN Stack Developer. - Strong understanding of trunk-based development and its best practices. - Prior experience working in an agile environment with regular sprints. - Proficiency in MongoDB, Express.js, React.js, and Node.js. - MUST MUST be proficient with Docker and build architectures. - Familiarity with version control systems, particularly Github and Github Actions. - Excellent problem-solving skills and attention to detail. - Strong communication skills and the ability to work collaboratively in a team environment. - Ability to manage multiple tasks and deadlines effectively. **Nice to Have:** - Experience with DevOps practices and tools. - Knowledge of serverless architecture and cloud platforms. - Familiarity with continuous integration and continuous deployment (CI/CD) pipelines. - Typescript experience. If you're after a easy going developer role where there's more work then we can get through then please let me know. No agencies and please only apply if you're used to throwing code out from ticket reference branches - we want to be pushing/building multiple times a day in some situations. Please please please do not apply if you're a junior or mid dev - this requires an individual to undergo a steep learning curve and drive the migration to finalisation. Also - the individual needs to work on the project full time until complete - this is not something that can be done in an hour a day.

Magento 2 – Fix Ryft Payment Webhooks (Lightweight PHP)
I am running a Magento 2 multi-store environment with a Ryft payment gateway already integrated. The majority of the system is in place, but I need an experienced Magento 2 / payment gateway developer to audit, verify, and correctly finalise the Ryft webhook implementation. This is a senior-level technical task focused on correctness, performance, and reliability. Critical requirement (please read carefully) The Ryft webhook must be handled using a lightweight standalone PHP endpoint. ❌ NOT using Magento bootstrap (app/bootstrap.php) ❌ NOT loading the Magento framework just to receive webhooks ❌ NOT relying on heavy Apache or Magento routing The webhook should be received in plain PHP, validated, deduplicated, and only then pass confirmed data into Magento in a controlled way. The goal is minimal server load, high reliability, and zero duplicate processing. Current situation Magento 2 multi-store setup (many stores, shared codebase) Ryft payments are mostly working Webhooks are unreliable or not firing consistently Some order duplication and inconsistent order state updates Current implementation may be too heavy and loading Magento unnecessarily What I need you to do Review the existing Ryft payment and webhook configuration Verify webhook events are correctly received (eg captured, failed, refunded) Implement or correct a lightweight PHP webhook endpoint Validate webhook signatures securely Ensure idempotent processing (no duplicate order updates if Ryft retries) Ensure correct Magento order state updates once events are confirmed Confirm the final setup is production-safe and correctly architected What I am NOT looking for A full Magento rewrite Magento observers handling webhook ingestion Any solution that loads the Magento framework to receive webhooks Required experience Magento 2 (checkout flow, order states, payment modules) Payment gateway integrations Webhooks, retries, signatures, and idempotency Clean, efficient, production-grade PHP Budget This is a senior task. Fixed budget up to £750, depending on approach and experience. To apply, please answer BOTH questions below: Why is it bad practice to load Magento’s bootstrap when receiving payment webhooks, and what impact does this have on PHP-FPM and server load? How would you design webhook processing to prevent duplicate order updates if Ryft sends the same event more than once? Applications that do not answer both questions will not be considered.
