Software Development Engineer · Flipkart

Bangalore, India · SDE, Trust and Safety (TnS) Team
  • Engineered and optimized low-latency distributed microservices within the core checkout path to enforce automated customer history analysis and secure, real-time risk classification.
  • Developed high-throughput transaction evaluation pipelines processing multi-million daily events to run active fraud detection rules, mitigating malicious actors without increasing user checkout friction.
  • Collaborated with data science and risk operations units to integrate intelligent workflow automation and contextual signals into distributed decision trees, optimizing data extraction and microservice isolation layers.

BGMI streamer toolkit

A web app + companion mobile app for Indian BGMI streamers and gamers — built because the existing tooling is fragmented. Goal is to give creators a single dashboard for sensitivity configs, tournament tracking, and stream overlays. Backend in Spring Boot, mobile in React Native, designed mobile-first.

Also shipped.

Six live sites — scoped, built, and supported independently.

None of these were assigned to me. I found the businesses, pitched, scoped, built, and shipped. The fastest engineering education I've had — because the feedback loop is the owner calling you when something breaks.
