What I'm looking for

I seek roles where I can build performant user-facing applications and developer tools, lead small teams, and drive product impact at scale while contributing to open-source.

I am a Frontend Engineer with 6+ years building production-ready web applications, developer-focused tools, and scalable architectures. I have led small teams, contributed to open-source, and delivered high-impact products from 0→1 while optimizing performance and developer onboarding.

Notable achievements include leading an MVP with 4,000+ monthly users, publishing and maintaining an NPM package to halve integration time, integrating major wallets for dApp use, implementing i18n in 16 languages, and improving transaction success rates and frontend performance through robust engineering and documentation.
