Matthew Kulka
Software engineer. I build web apps — from real-time collaboration and 3D to AI and the tests that keep it all working.
I came up through QA and SDET work and moved into frontend and full-stack development — so I build products with a real instinct for what holds up. The projects below are all live and open source.
Open to Senior SWE / SDET / full-stack. Selective — the right team over the next title.
