about_me.md

I'm a software engineer who lives where mobile performance meets product impact. At Zepto's Mobile Platform & Architecture team, I took the consumer app through the React Native New Architecture migration — untangling Fabric, TurboModules and bridgeless layers while keeping crash-free rates above 99.9%.

I like building things that compound: OTA update pipelines that ship fixes in minutes, media platforms that unify 20+ fragmented utilities, and conversational AI schedulers that let non-engineers move fast without breaking things.

Off the keyboard: badminton champion (3× district, ICSE zonals), led a 90+ member contingent at Inter IIT Tech Meet, and once ranked AIR 1043 among 1.2M JEE aspirants.

Software Engineer — Mobile Platform & Architecture

Jun 2025 — Present

@ Zepto · Bangalore

  • Led RN 0.73 → 0.78 migration & New Architecture rollout across the consumer app — resolved 150+ issues spanning Fabric, TurboModules & bridgeless layers; restored crash-free rates to 99.94% Android / 99.98% iOS.
  • Shipped ~20% Android and ~7% iOS homepage load wins, ~10% Order Tracking uplift, contributed to ~76% ANR reduction; authored TurboModule playbooks adopted org-wide.
  • Led the Android ANR reduction initiative — optimized React Native startup during background FCM delivery, cutting Play Vitals ANR rate 41% (0.34% → 0.20%) across 17M+ sessions.
  • Built Zepto Lite Mode (iOS) — native Swift modules sensing battery/network to shed GPU-heavy surfaces, driving +0.79% Home→Order conversion.
  • Created an AI MerchOps scheduler (LangGraph + OpenAI) letting non-technical teams schedule banners/widgets conversationally — retired manual cURL workflows.
  • Drove Electronics Revamp (~20% conversion uplift) & search experiments (+0.94% Search→ATC).
  • Architected a unified Media Optimization Platform, consolidating 20+ fragmented utilities into one ImageKit-backed transformation layer.
