Have a project in mind? Let's talk.

Stephen Mulyadi

Full Stack Developer

I'm a full stack developer in Jakarta. I build mobile and web apps with React Native, React and TypeScript, and the Node.js and GraphQL backends they run on. I've been doing this for clients since 2019, first at Kodefox and now at Skyworx.

01 / About

Who am I?

Hi, I'm Stephen. I've worked as a full stack developer since 2019, first at Kodefox and now at Skyworx, building software for clients. Most of my work is in TypeScript: React Native and Expo on mobile, React and Next.js on the web, and Node.js, GraphQL and PostgreSQL on the server.

I like hard problems, and I care about apps being easy to use. Outside work I cook, go for walks or a jog, and read up on whatever I'm curious about that week.
