import { Bio } from “Profile”

I’m JS Developer with 10+ years of commercial experience building web and mobile applications across
fintech, crypto, betting, and SaaS products. My core stack is React, TypeScript, MobX, NextJS and Tailwind - with
a solid full-stack background in Laravel and Node.js that helps me collaborate effectively across the entire
product. I've worked with international teams in Germany, South Africa, and Ukraine, and I'm fully comfortable
in async, remote environments. I can work independently from day one - including when design specs are
incomplete or absent - and I bring genuine UX sensibility to everything I build.
