I'm Chandra, a Principal Software Engineer (Mobile) at mPokket in Bangalore. I lead the Flutter work on SkillZi, a learning and rewards app used by 100K+ people.
In 8+ years across FinTech, HealthTech, EdTech and HRMS, I've led teams of up to 15 engineers (Flutter teams of up to 8), taken an AWS digital health platform from concept to MVP as Technical Architect, and shipped apps that held 99.8%+ crash-free users.
I go deepest on Flutter architecture, Bluetooth LE and wearables, payments and app security. Chandra means moon in Telugu, which is why there's one up there.
