01 / About

The engineer
behind the build.

I'm a Founding Engineer who thrives at the intersection of pixel-perfect UI and robust architecture. With 6+ years in Flutter, I went from freelance delivery to owning the entire technical stack of a funded startup.

At Kolab, I built the platform from scratch: every architectural decision, every line of Dart, every CI/CD pipeline. That means designing the BLoC state management layer, integrating Firebase realtime infra, orchestrating Stripe billing and custom web checkout, and shipping to the App Store & Play Store solo.

I'm fluent across the mobile dev lifecycle: from system design and DI setup to smooth animations and app performance profiling. I code with clarity and ship with confidence.

KOLAB (KLICKR TECHNOLOGIES) · Pune, India
Led all technical decisions and engineering at a creator-brand collaboration startup, building from zero to a live product on iOS, Android, and Web. Solo, end-to-end.
  • Architected the entire Flutter client following Clean Architecture principles, with BLoC + HydratedBloc state management, go_router navigation, and get_it dependency injection. Testable, scalable, and built to last.
  • Built Tinder-style swipe matchmaking between brands and creators with rate-limited super-swipes and a real-time match system using Firestore.
  • Integrated Stripe for payments and built a custom web checkout flow for subscriptions, handling the full billing lifecycle in-house.
  • Shipped an AI-powered onboarding chat (Claude/OpenAI) via a FastAPI Cloud Run sidecar with Cloud SQL persistence.
  • Set up end-to-end CI/CD with Fastlane for iOS TestFlight builds and automated App Store Connect uploads.
  • Designed a multi-account system with seamless context switching, FCM token refresh, and Firestore stream resets.
