Projects

Things I have built and shipped publicly, rather than designed on paper. Source is open, licences are permissive, and you can clone any of it and run your own instance today, including the one still being built in the open.

01
RAG Platform · Self-hosted · MIT

DocuSage

A self-hosted AI chatbot that answers from your own PDF documents, embeddable on any website with one script tag. Multi-project, multi-tenant, and not tied to one model vendor, OpenAI, Gemini or Azure OpenAI, chosen per project. Your infrastructure, your keys, your data.

Local-first AI Dubbing · Alpha · MIT In development

Dabuj

A transcription, translation and dubbing studio that runs entirely on your own machine. Commercial dubbing services need your media uploaded to someone else's computer, a poor fit for unreleased footage, confidential interviews or client work under NDA. Pick local providers and nothing about your media leaves the machine: no uploads, no API calls, no telemetry. Transcription runs end to end today; translation and re-voicing are next on the roadmap.

// More coming

More open-source work lands here as it gets published. If you want the design thinking behind systems rather than the code, the case studies are the other half of this.
