5 years building production React Native and React.js apps — from healthcare platforms and social apps to a banking super app at one of Indonesia's largest banks. I specialize in API integration, state management, and shipping clean, scalable mobile UIs.

I've delivered 10+ production apps across full-time and freelance roles, consistently meeting deadlines and maintaining high code quality. I work well independently, communicate proactively, and I'm fully remote-ready.

I'm also open to fullstack roles — I have hands-on backend experience with Node.js and Express.js, and I'm currently deepening my knowledge in Node.js and Golang to become a more well-rounded engineer.

Open to freelance projects and long-term contracts in frontend, mobile, or fullstack development — preferably with teams that value clean code, clear communication, and real ownership over the product.
