I’m a Lead Software Engineer

13 years building mobile at consumer scale — apps with 10M+ downloads that cannot afford downtime.

Now I’d rather help other engineers ship them.

About

Built at scale.
Taught in public.

Mobile engineering leader, 13 years across Flutter, native Android and native iOS — and React and Next.js on the web. I lead teams of up to 7 engineers and own architecture from design through release.

  • Experian Credit Score3.7M downloads4.6

    Protect-domain features across Flutter, mobile webviews and the React and Next.js web app, with Snowflake analytics wired through both.

    • Integrated the Experience 3.0 API so the interface branches on subscription: Free and Paid customers get the Flutter native flow, longstanding customers get webviews.
    • Fixed the navigation that stranded customers upgrading from the billing page — they could not get back to where the journey began. Profile, Home, Score and Report shipped the same correction afterwards.
    • Unit, widget and golden tests throughout, using the Alchemy package.
  • MoneyControl10M+ downloads7–8M monthly actives

    Watchlist, real-time market data and the portfolio tracker, built in Flutter and injected into the live native apps through Add-to-App, bridged with Pigeon-generated method channels — no rewrite, no release freeze.

  • CITI Mobile10M+ downloads4.8

    Chat support integrated onto a standalone server-driven UI module that renders the whole experience from the customer's login and account type.

  • Huntington1M+ downloads4.8

    Zelle payment gateway integration, biometric authentication, and account-type handling so savings, current and the rest each render their own experience.

Today I am the creator and sole engineer of Inspectro. I am in Hyderabad, and open to new opportunities.
