    About

    Principal engineer with fifteen years across backend, platform and multi-tenant analytics — lately architecture, design systems and developer experience. (PLACEHOLDER bio)

    After hours I build instruments: a HUD design language extracted from a shipped product, and a live dashboard for coding agents.
