About

Backend Engineer with 3+ years building high-throughput distributed systems at scale. At Ernst & Young, I engineered batch processing pipelines that generated 26M+ ABHA health IDs, and built async workflows using Kafka and Redis that power mission-critical government infrastructure. At KPMG, I led ingestion of 67M+ PDS records into scalable microservices — owning the full pipeline from API design to production deployment.I specialize in Java, Spring Boot, Kafka, and Redis, with a strong foundation in system design and performance optimization. I don’t just build features — I own systems end-to-end, from architecture decisions to reliability in prod.Open to backend/SDE roles at product companies solving infrastructure and scalability challenges at scale.
