Profile

Full-stack developer since 2023, sole developer of a multi-screen platform in production. I care about sound architecture (monorepos, clean architecture, APIs typed end to end), accessibility and tests. I follow release notes and keep my projects on the latest versions of their ecosystem. I use AI agents every day, down to building their tooling.
