Senior🎓
Top SchoolSeunghwan Lee is a mobile engineer with 9 years of experience specializing in Flutter-driven architecture, performance, and delivery optimization for high-traffic e-commerce platforms. He led a Clean Architecture migration that cut memory use by 50%, reduced initial data load by 78%, and lowered churn by 7% for a 210K MAU product, while also building 700+ tests that hardened production reliability. Beyond app code, he designs developer-facing infrastructure—creating a FastAPI + Fastlane CI/CD that shrank deployments from 4 hours to 15 minutes and automated Figma → Flutter workflows to boost efficiency. He pairs hands-on engineering with mentorship and tooling (custom_lint, Widgetbook components, JSON→Dart generators) to raise team productivity and reduce repetitive errors. Based in Seoul, he enjoys solving real customer problems with pragmatic architecture and has a track record of using AI-assisted analysis to safely modernize legacy codebases.
