Architected and delivered a full-stack hyperlocal commerce platform on Flutter Web and Firebase, encompassing customer shopping, cart, WhatsApp-based ordering and authenticated admin workflows. Defined feature-based Clean Architecture with Cubit/BLoC state management and reusable Firebase data/application layers. Implemented end-to-end product catalog, order lifecycle, real-time status updates, image storage/caching and responsive Material 3 UI. Integrated Gemini-powered content generation and GitHub-based product-data automation.
Designed a Python-based NSE equity trading automation system leveraging Angel One SmartAPI, 5-minute market data, EMA 9/21, VWAP and volume confirmation signals. Built broker-verified execution, SQLite persistence, position reconciliation, duplicate-order protection, kill-switch and daily risk circuit breakers. Separated paper and live execution paths; packaged Ubuntu/systemd deployment with market-hours scheduling and health monitoring.
Developed a real-time trading observability SPA providing portfolio/P&L, positions, trades, orders, Telegram signals, risk/health metrics and analytics. Implemented event-driven data refresh with TanStack Query and a native WebSocket manager featuring exponential backoff, reconnect handling and event deduplication. Delivered a responsive dark-first terminal UI with charting, strict TypeScript contracts, automated frontend tests and production-grade deployment/security configuration.
