ABOUT UMANG AGRAWAL
Backend Engineer with 3+ years of experience building scalable, reliable systems that solve real-world problems.I’ve designed and delivered backend services that fix financial mismatches at scale and support thousands of users daily — using technologies like Node.js, PostgreSQL, MongoDB, and cloud-native tooling.I’m driven by ownership and long-term system reliability — whether it’s reducing downtime from hours to minutes, optimizing database performance, or building clean, auditable workflows with rollback and recovery.I enjoy working closely with product and infra teams to ship stable, user-first systems — and making backend work feel invisible, because when it works, no one notices.
