Hi, Iām Nico Lin.
Senior Flutter Engineer.
I specialize in Flutter and native Android (Kotlin), with hands-on experience across iOS (Swift) and React Native. Over 8+ years in mobile engineering, I design scalable Clean Architectures and build production apps that scale to 1M+ users.

About Me
Hi! I'm a Senior Flutter Engineer based in Indonesia, with 8+ years across mobile engineering. I work primarily with Flutter, though I'm always ready to switch over to native Swift, Kotlin, or React Native whenever needed.
Beyond mobile, I also do full-stack work using tools like Next.js and Go. I focus on writing clean, solid code, using AI tools like Claude Code to boost my daily productivity, while enjoying the hands-on challenge of debugging tricky production bugs.
I've also led engineering teams, including managing 24 engineers as a Technology Manager and driving Agile/LeSS adoption.
In my free time, I enjoy exploring new tech, optimizing app performance and architecture, and finding ways to make developer workflows faster.
I also built and maintain the Flutter Enterprise Starter Kit: an open-source project set up the way I'd structure a real production app, featuring Clean Architecture, Cubit, dependency injection, offline caching, multi-flavor builds, and CI/CD via GitHub Actions and Fastlane.
Right now, I'm looking for remote opportunities to work with global teams.
