I build for the pocket.

I architect Flutter apps that ship. 8+ years, 1M+ users, 200+ clients, and a few quiet 3am production fires later — I still love the platform. Currently shipping Ezycourse at Appifylab — an LMS serving 200+ institutions and a million-plus learners.

01 — About

A decade in motion.

From WordPress sites in 2017 to Flutter monorepos shipping to a million users — same person, longer feedback loop.

I'm a Senior Mobile Engineer with eight-plus years building cross-platform applications that scale. I've led teams of five to twelve, mentored juniors into seniors, and stood up CI/CD pipelines that cut deployment time by 60%. My happy place is the intersection of Clean Architecture, BLoC, and performance budgets — where elegant code meets a 60fps frame.
