Tarun Kumar

I build and ship production-grade mobile applications with 3+ years of hands-on experience across academic and professional work. I focus on enterprise-ready architecture, performance-critical UX, and systems that stay reliable under real-world load.

As Team Lead – Mobile Development at Kartavya Technologies (Terrabiz Tech), I owned end-to-end architecture for an enterprise HR/ERP platform serving 3,000+ daily active users across partner organizations. I engineered high-accuracy background location tracking using Flutter Platform Channels, improving system reliability by 40% while reducing GPS drift and device battery drain, and I delivered biometric attendance, geofencing, asset tracking, and real-time trip monitoring to replace manual HR workflows.

I also lead delivery with measurable outcomes: introducing layered BLoC architecture and a shared UI component library reduced new feature development time by ~25%, while Codemagic CI/CD pipelines helped maintain 99%+ release stability. From zero to App Store launch on VisaCast, I built a WebSocket-driven, AI-powered consultation engine with sub-200ms latency and crafted immersive Flutter UI (Custom Painter + advanced animations) that contributed to a 4.6+ launch rating.
