Work Experience

Software Engineer — Google

  • Cloud Storage & AI Infrastructure: Designed and built a protective isolation platform that shields core cloud storage systems from heavy AI/ML traffic spikes, keeping critical services fast and available under peak demand.
  • Performance & Cost Efficiency: Optimized core backend services and gRPC communications, cutting compute resource usage by 26.4%, reducing end-to-end latency by 17.2%, and boosting library speeds by 50%.
  • System Reliability & Stability: Re-engineered multithreading architecture to prevent system deadlocks, eliminating over 10M bottlenecked scheduling operations per second across the fleet.
  • High-Load Outage Prevention: Implemented intelligent server-side load management on metadata servers, eliminating out-of-memory crashes during extreme traffic surges.
  • E-Commerce Platform (Google Shopping): Built modern order management APIs and migrated authentication systems to Google Cloud Spanner, preventing transaction errors for 16.2% of global shopping requests.
  • Security & Fraud Prevention: Created an internal rule compiler and translation tool that increased mobile on-device fraud and abuse detection coverage from 0% to 68%.
  • Mentorship & Leadership: Certified C++ Readability Mentor conducting 150+ code reviews, led 10+ hiring interviews, and guided 3 engineers through onboarding and career progression.

Software Engineering Intern — Honey (PayPal)

  • Full-Stack Development: Built user-facing React web components and Node.js backend microservices using GraphQL and Google Cloud Platform.
  • Automation & Engagement: Engineered automated coupon optimization across 50+ major retail partner sites, improving checkout savings and user engagement.
