Lucas Veiga · backend engineer

I build software that delivers on its promises.

I work primarily with PHP and C#/.NET, building robust backend systems and practical tools to solve daily problems. When I'm not coding, you'll find me contributing to open source, mapping in osu!, or tinkering with Linux.
