Available to hire
Hi, I’m Boris Kartapov, a Flutter developer with 5+ years of commercial experience. I specialize in native integrations and cross‑platform development, including building a Flutter plugin for hardware scanner SDKs (Atol, Honeywell, Urovo) via Platform Channels, and shipping apps across Android, iOS, Web, Aurora, and Desktop.
I’ve delivered enterprise applications for Rostelecom, MTS, Magnit, and Wildberries. I’ve led mobile teams, driving architectural decisions, conducting code reviews, mentoring developers, and handling technical interviews. I favor pragmatic tech stacks (BLoC/Riverpod/MobX with Clean/MVVM and modular architectures) and actively leverage AI tools like Cursor, Claude Code, and Qwen‑Code to boost productivity.
