I think in systems, ship in details.

// 01  about

Software that lasts — from front-end to system.

What gets me going is software that still runs cleanly years later. As an application developer and technical lead for the JavaScript domain, I'm the technical authority around JavaScript and TypeScript — I'm the one consulted on the tricky calls, I help set the direction, and I keep standards that hold. I'm at home across the entire web stack: considered front-ends with Vue, performant back-ends, close to the system with Rust and Go, plus a confident command of databases. Professionally I build GEO-IT software and I'm deep in geoinformatics — a field that still keeps me tinkering. What really draws me in are complex problems: for every one I find a clean, maintainable solution. From concept through architecture to the last pixel.
