I’m building the 5Paisa mobile trading application in Flutter, focusing on real-time market data rendering for Android and iOS with backend-first data integrity. I own performance-critical modules like Positions, Portfolio, and MTF over high-frequency WebSocket streams.

I’ve profiled and optimized rendering pipelines to keep smooth scrolling and 60 FPS across large, dynamically updating lists with real-time price tickers. I also work on complex state reconciliation and optimistic UI updates.

At Betafront Technologies, I developed Belong across 6+ fintech modules and drove performance improvements through frame rate optimization, memory profiling, and async data pipelines—especially for lower-end devices. I also authored native SDKs (Android AAR and iOS xcFramework) and exposed banking services to partner apps via platform channels.

Before that at Brane Enterprises, I engineered a cross-platform design language system and a No-Code UI Builder in Flutter across Android, iOS, Windows, and macOS. I led a team of 40 developers and shipped 10+ production-ready applications from the UI Builder.
