What I do
I design and redesign Flutter mobile applications — iOS and Android — for B2B SaaS agencies and publishers. I act as a lead dev, from architecture to production deployment.
My approach
Clean Architecture, Riverpod, Firebase, and Google Cloud — to deliver a maintainable and tested codebase from the start, without technical debt to manage later. A team taking over the project after me should be able to do so without getting lost.
What I usually handle
Mobile MVP launches · Redesign of existing Flutter applications · REST and Firebase API integrations · Technical structuring of junior teams
Some achievements
- JetBrains Dart extension — over 8,500 downloads
- Unio — dating app with AI matching engine and real-time events
- Several lead dev and technical coaching missions on production Flutter projects
