Senior software architect & full-stack developer, building secure, AI-native software from France π«π·
I've spent 10+ years shipping SaaS products, AI features, and secure web apps across 120+ projects for 50+ clients. I care about code that holds up under load, code that holds up to audit, and tools small enough to actually understand.
Building polaris a lightweight RAG over MCP for coding agents, alongside other Rust-based AI tooling and developer infrastructure. Small, sharp tools that do one thing well.
polaris Lightweight RAG system for coding agents. Index your project docs, search them semantically, serve results over MCP. Single-binary deployment. (Rust)
md2pdf A markdown-to-PDF library that's actually correct. (Rust)
I take on a limited number of client engagements:
- Full-stack development SaaS products, AI-powered features, secure web apps
- Frontend architecture design systems, performance, framework migrations
- Technical consulting & code audits second opinion, security review, scaling advice
- Mentoring for individual engineers and small teams

When I'm not shipping code, I train Filipino Boxing and FMA (Filipino Martial Arts). Distance, timing, and flow, turns out it's not that different from systems design.
