Asim O.
Senior Flutter Developer | Mobile Apps | AI-Assisted Engineering
🚀 Senior Flutter Developer with 12+ years in software engineering and 6+ years building production Flutter apps for iOS and Android. I help companies build, improve, and ship reliable mobile products — from architecture and development to App Store & Google Play release. Whether you're starting a new product, scaling an existing app, or need someone to take ownership of a complex Flutter codebase, I can step in and handle the mobile side end-to-end. 📱 WHAT I CAN HELP YOU WITH • Flutter & Dart development for iOS and Android • MVPs and production-ready applications • Existing app takeover, refactoring & modernization • Clean Architecture, BLoC/Cubit & Riverpod • REST APIs, WebSockets, Supabase & Firebase • Offline-first apps with Drift / SQLite • Authentication, social login & deep linking • Push notifications • Subscriptions & in-app purchases • Native integrations with Swift, Kotlin & platform channels • Performance optimization, crashes, jank & memory issues • Unit, widget, integration & golden testing • CI/CD, App Store & Google Play releases 🤖 AI-ASSISTED ENGINEERING I use Claude Code, Cursor, custom AI workflows, subagents and MCP integrations throughout planning, implementation, testing, refactoring, debugging and code review. AI helps me deliver faster — while architecture, technical decisions, code quality and production responsibility remain under my control. My workflow includes project-specific AI rules, custom commands and skills, automated testing, CI quality gates, and integrations with tools such as Figma, GitHub, Supabase and Flutter/Dart. 🧠 PROVEN EXPERIENCE Most recently, I took two Flutter applications from an empty repository to beta as the only mobile engineer — owning architecture, implementation, backend integration, testing and delivery. I’ve also worked on a high-scale real-time Flutter product involving offline-first architecture, WebSockets, native SDK integrations, performance optimization and production monitoring. I bring 2+ years of technical leadership experience, leading teams of 4–6 engineers across architecture decisions, mentoring, code reviews, planning and delivery. 📩 LET'S BUILD If you need a senior Flutter engineer who can understand your product, make strong technical decisions and take ownership from development to release, send me a message and tell me what you're building.
