I build personal digital environments people can trust, at home and at work, with as little dependence as possible.

Polymer engineer by training, self-taught developer. My work starts from three questions: who owns your knowledge, who decides what reaches it, and how can it save you time and space?

My code lives on my own forge, forge.lockilabs.com, self-hosted. GitHub carries the mirrors: a project comes here when it is ready to be shown.

Updated daily from the forge. Counts only: no titles, no private repo names.

• Sovereign by design. A personal environment rebuilt piece by piece: cloud applications where a tool is genuinely useful, self-hosted where the risk is too high, every choice reconsidered, from the commercial chat to the browser.
• AI agents that serve the decision, not replace it. Self-hosted RAG and specialised agents, every action traced, the human always in the middle. Running daily across 17 projects.
• Data engineering for industry. ETL pipelines, Rust microservices, predictive and risk models for manufacturing, plastics and finance.

A semantic layer for several people, each owning their own knowledge: one shared vocabulary, with work and personal knowledge kept clearly apart.

• ocapistaine: civic AI agents grounded in a town's public archives
• hero-skulth: can we trust smart contracts in the era of AI agents?
• locki-io.github.io: not a video game, but UX pushed to its limit

Some commits here are made by lothi-vaettir, the assistant I run. Every one of them points to a decision I recorded before it was made, available on request.
