Android engineering for products that scale, ship, and hold up in production.

10+ years building production Android across e-commerce, fintech, and fantasy sports — including platforms serving 5M+ active users. I own the parts that decide whether a product survives contact with real traffic: architecture, reliability, performance, and release discipline.

01 — Impact

Proof before promises.

Architecture ownership, reliability, and conversion — the work that decides whether an Android product holds up at scale.

Platform

Owned Android architecture across feature squads.

Set module boundaries, shared components, and engineering practice for one of India's largest furniture e-commerce apps.

  • 5M+active users on the platform
  • Multi-modulemigration led end to end
  • 3–4engineers mentored on architecture
Reliability

Cut instability at the source, not the dashboard.

ANR analysis, thread profiling, and background task discipline instead of chasing symptoms in Crashlytics.

  • 35%crash-rate reduction
  • Cold startimproved via lazy initialization
  • ANRprofiling and thread analysis
Ownership

Shipped independent products end to end.

Not just features — subscriptions, persistence, AI APIs, Play Store releases, and the analytics behind them.

  • 9apps live on Google Play
  • 22%checkout conversion improvement
  • < 3 moconcept to Play Store launch
02 — Selected work

Products, not project cards.

Independent products built and released solo — architecture, AI integration, billing, and store operations. Mostly Android, plus one web product where the problem called for it.

AI Scam Detector

WhatsApp fraud protection for Indian families

A WhatsApp bot that analyses forwarded messages for fraud — fake KYC blocks, lottery wins, utility-disconnection threats — and returns a structured risk report with a confidence score and what to do next. Built on Gemini 2.5 Flash for both text and image analysis, with regional-language handling across Hinglish, Hindi, Marathi, and Tamil.
