Hutomo — Mobile Development freelancer in Sambas

Hi, I’m Hutomo — a Top Rated engineer on Upwork with a background in mobile development, backend systems, and performance-focused tooling. I’ve spent several years building and maintaining production applications, primarily with Flutter on the frontend, and TypeScript, Go, and Postgres-based systems on the backend. More recently, I’ve been working with Rust and WebAssembly for client-side and systems-oriented projects. I’m comfortable working across: - Mobile apps (Flutter, iOS) - Backend APIs and databases - Real-time systems - CI\u002FCD and deployment - Performance-sensitive client-side tools I value clear communication, realistic planning, and building things that are easy to maintain long-term. If you’re looking for a dependable engineer who can think beyond just UI or just backend, feel free to reach out. — Hutomo
