Ario Budi Widagdo

Senior Frontend Engineer

I build fast, reliable web & mobile apps — from enterprise banking platforms to consumer apps for Telkomsel.

5+ years shipping production code with React.js, Next.js, TypeScript and React Native. I’ve built a Wealth Management System used by multiple banks in Indonesia, worked on Telkomsel’s MyOrbit, and I’m comfortable going beyond the frontend — Go backend features, deployments, and production troubleshooting included.
