About

Backend-focused Software Engineer with 5+ years of experience in building scalable, low-latency systems. Currently at Goldman Sachs, where I design regulatory and trading control systems using Java, Spring Boot, Kafka, and MongoDB. Proficient in Golang and Python, and experienced in event-driven architecture, microservices, and distributed systems. At UIDAI, I helped modernize Aadhaar infrastructure — from sub-second Solr-based search to Kafka-backed data replication. I thrive on building backend systems that are not just fast, but resilient, observable, and cleanly designed. Passionate about system design, architecture, and solving algorithmic problems. Actively improving on LeetCode and exploring backend infra projects. Open to backend/platform/infra roles in fast-moving, product-focused teams.
