About

Software Engineer with 4+ years of experience building production-grade mobile apps, web frontends, and full-stack systems across government, healthcare, and enterprise domains. On the mobile side, I specialize in Flutter (Dart) and Native Android (Java/Kotlin) — delivering cross-platform apps with offline-first architecture, GPS/geotagging, real-time sync, state management (BLoC, GetX, Provider), and Play Store/App Store deployments. Reduced app crash rates by 35–40% through systematic debugging and performance optimization. On the web and backend side, I work with React/TypeScript for frontend portals and Node.js/Express with MongoDB and PostgreSQL for API design and server-side logic — including production deployments in government land records systems. I bring clean architecture thinking (MVVM, Clean Architecture), strong API integration skills (REST, JWT), and a track record of shipping reliable, maintainable products on schedule. Core stack: Flutter • Dart • React • TypeScript • Node.js • Express • MongoDB • PostgreSQL • Firebase • SQLite
