What I'm looking for

I’m looking for a team that values clean architecture, strong testing, and reliable CI/CD. I want to build Flutter products end-to-end, integrate IoT where relevant, and keep improving performance, stability, and delivery speed.

I’m a Senior Flutter Developer with 5+ years building high-scale mobile apps in fleet management, real estate, and e-commerce. I focus on clean architecture and UI systems (Atomic Design), and I partner across teams to ship measurable improvements—like 45% engagement lifts and 35% cost reductions.

Across my roles, I’ve owned core app architecture, including real-time vehicle tracking, IoT controls, geofencing, and driver behavior monitoring. I also operationalize reliable delivery with Fastlane and GitHub Actions, enforce unit/UI testing standards, and use Sentry for real-time crash monitoring—so releases go live faster and with fewer critical defects.
