I've been building production Flutter applications for 5+ years, from enterprise mobility tools to consumer apps with 100,000+ users. I've achieved a 99.5% crash-free session rate on an app used daily by 300+ field engineers, cut release cycles from two weeks to three days by implementing CI/CD pipelines, and taken a solo project from design handoff to launch, improving its store rating from 3.2 to 4.5 stars. I'm looking for a senior remote Flutter role where I can own features end-to-end and bring an AI-augmented workflow to a product team. What sets me apart is combining deep Flutter/Dart expertise with Clean Architecture discipline, offline-first engineering for unreliable networks, and a track record of mentoring junior developers while shipping reliably under enterprise constraints.
