Software Engineer with 7+ years of experience building mobile and web applications end-to-end. I lead cross-functional teams, architect microservices migrations, and ship products across retail, agriculture, social, and hospitality domains. Proven track record of taking projects from zero to production as a solo developer and leading teams of up to five engineers.

• Mobile Development: Flutter, Dart, Android, iOS
• Backend & APIs: Node.js, NestJS, TypeScript, REST APIs, WebSockets
• Databases: MongoDB, PostgreSQL, SQLite, Firebase, Cloud Firestore, Redis
• Infrastructure & DevOps: Docker, Kubernetes, AWS, GCP, CI/CD (GitLab, Jenkins, GitHub Actions)
• Tools: Figma, Sentry, Google Analytics, Datadog

Building two MVPs from scratch as the sole developer:

• Social Discovery App (US Market) — Designed a multi-provider data aggregation layer integrating Tripadvisor, Viator, and Google Maps APIs with provider-specific caching and a feed ranking system balancing freshness, cost, and relevance.
• Real-Time Dine-In Reservation App (Indian Market) — Designed a real-time dine-in reservation platform from the ground up. Implemented live location sync between customers and restaurants with event-driven logic that coordinates meal preparation timing with customer ETA, triggering automated workflows such as order locking and kitchen prep.

• Developed retail and farming modules for a fresh-cut industry leader, replacing spreadsheet-based workflows with real-time digital coordination and crop planning tools that reduced setup time from three days to seconds.
• Built a centralized communication platform replacing phone calls with structured requests, approvals, and instant notifications. Developed migration tools and delivered fully responsive Flutter apps across mobile and web.

• Built a Flutter-based dating app from scratch, owning the full lifecycle from repo setup through feature delivery. Established CI/CD workflows and testing frameworks covering unit, widget, and integration tests.
• Promoted to lead a five-member web team. Architected the migration from a monolithic backend to microservices using NestJS, Docker, and Kubernetes. Managed CI/CD pipelines and drove performance optimizations across deployed services.

• Developed applications across healthcare, transportation, and education — delivering real-time scheduling, live location tracking, automated billing, and interactive VR courses for Oculus Go.
