I've built real-time trading platforms, digital signage features, and high-performance web applications across Poppulo and 5Paisa Capital. At Poppulo Digital Signage Cloud, I develop React and TypeScript features for AnalyzeAgent, including AI-driven chat, charts, and recent conversations.
I've improved WCAG-aligned accessibility across 90%+ of user-facing flows, increased frontend rendering efficiency by 25–30%, and maintained 80%+ unit test coverage with Jest. I also resolve Node.js security vulnerabilities and support AWS SDK upgrades to improve service stability.
At 5Paisa, I helped build TRADESTATION and led charting work used by 50,000+ active traders. My custom TradingView and ChartIQ implementations served 2M+ daily chart requests, while WebSocket updates and rendering optimization reduced chart latency from 800ms to 80ms.
