Host deploy and test and existing app

This project aims to deploy, on a dedicated VPS server, the complete environment required to run the WHIMO solution developed by the European Forest Institute. WHIMO is an Android application designed to collect, store, and transfer geolocation data to support compliance with the EU’s EUDR regulation. To operate properly, the mobile application relies on a stable, secure, and publicly accessible backend environment. The mission is to deploy, configure, and secure all backend services of WHIMO using the official GitHub repositories, and to ensure that the API is fully operational so the Android application can connect to it. This includes preparing the VPS, installing all dependencies (Docker, PostgreSQL, Redis, Gunicorn, HTTPS reverse proxy), setting up Firebase credentials, configuring the network and security layers, and delivering complete technical documentation. The final objective is to deliver a stable, secure, and operationnal hosted application on the new server environment, ready for use , while respecting best practices in development, security, and operations.

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?

Collabora Online + Nextcloud Integration – Issue

Collabora Online + Nextcloud Integration – Status & Outstanding Issue Environment Server: Dedicated Linux server (Plesk, EL9) Reverse proxy: Plesk-managed nginx (in front of Apache) Nextcloud: Self-hosted instance (HTTPS) Collabora: External Collabora Online server (Docker-based) Proxy model: nginx reverse proxy CDN / WAF: Disabled during testing SSL: Terminated at nginx (Collabora running without internal SSL) What Has Been Completed (and Verified) 1. Collabora container deployment Collabora Online is running in Docker Exposed internally on port 9980 Container starts cleanly and remains healthy Verified via direct local HTTP request: /hosting/discovery → HTTP 200 OK 2. nginx reverse proxy configuration nginx successfully proxies Collabora endpoints: /hosting/discovery /cool /browser WebSocket upgrades are enabled and functioning Verified externally over HTTPS: /hosting/discovery → HTTP 200 OK 3. SSL / proxy alignment SSL is terminated at nginx Collabora started with: SSL disabled internally SSL termination enabled This matches the reverse proxy architecture No TLS or certificate errors observed 4. CDN / firewall eliminated as a factor CDN/WAF fully disabled during testing Requests go directly from client → nginx → Collabora No CDN headers or interference present 5. Nextcloud Office configuration “Use your own server” selected External Collabora URL configured (HTTPS) Built-in CODE server disabled Demo server not used Admin UI reports Collabora as reachable 6. WOPI allow list configuration WOPI allow list configured in Nextcloud No token-based authentication configured Certificate verification left enabled (public certificate in use) 7. nginx validation nginx configuration validates successfully Reload performed via Plesk tooling No nginx syntax or runtime errors Current Behaviour (What Works) Collabora service starts normally Reverse proxy works correctly Discovery XML loads both: Internally (direct to port 9980) Externally (via HTTPS proxy) WebSocket connections establish successfully No networking, firewall, or SSL failures observed Current Issue (Still Failing) Error shown in Nextcloud UI Document loading failed Unauthorised WOPI host. Interpretation of the Error Collabora is rejecting the WOPI request Rejection happens after discovery and WebSocket setup This indicates a WOPI host authorisation failure, not a connectivity issue Likely Root Cause (High Confidence) The Collabora domain allowlist regex does not exactly match the WOPI host string generated by Nextcloud. Typical causes: Host includes an explicit port (e.g. :443) Regex not anchored (^ / $) Multiple valid hostnames not fully accounted for This is a known and common Collabora failure mode. Evidence Supporting This Conclusion Network path is fully functional SSL termination is correct Discovery and WebSockets work Error is specific to WOPI authorisation CDN/WAF is disabled Logs show normal Collabora startup and request handling up to WOPI validation Trying to get AI apps setup and working, trying to do this broke the Next docs.
