Shreyansh Rawat

I’m a software engineer with production experience at Google Pay, contributing to payment infrastructure serving 150M+ monthly active users. I focus on building reliable, secure services that maintain performance at scale.

At Google Pay, I optimized a wallet-to-bank transfer microservice by implementing async batching logic, reducing settlement latency by 40% and improving success rates to 99.9%. I also helped roll out UPI Lite for 150M+ MAU, developing Flutter UI components and Java backend endpoints that sustained 500+ TPS during peak loads.

I improve systems by tightening data flow and contracts—refactoring REST API payload structures to boost data efficiency by 30% and reduce downstream error rates by 15% through stricter validation logic. I’ve worked closely with senior engineers on high availability using Java, Guice, and Google Cloud Spanner, including on-call rotation and incident response.

I enjoy shipping real user-facing mobile capabilities as well as core backend performance work, including secure payment flows in Flutter/Dart aligned with financial security standards. In projects, I’ve built a hybrid edge-to-cloud multimodal AI agent and a zero-allocation MLOps engine to minimize latency and cost while keeping architectures maintainable.
