About

Backend-focused Software Engineer with 4+ years of experience building scalable distributed systems, payment infrastructure, and high-performance microservices. Currently working at ZUZU Hospitality, where I design and operate revenue-critical payment systems serving 2000+ hotels across India and Southeast Asia. My work focuses on Golang, Kafka, AWS, distributed systems, and backend scalability. I enjoy solving engineering problems around system performance, reliability, and architecture — from reducing API latency and optimizing databases to designing resilient async workflows with retries and idempotency.
