About

Backend-focused software engineer at PhonePe with hands-on exposure to high-scale production systems. I work primarily with Java, Spring Boot, REST APIs, and SQL , and I’m deeply interested in building clean, maintainable backend services and understanding system behavior at scale. I actively strengthen my foundations in data structures, algorithms, and system design. Alongside my professional work, I build backend projects end-to-end from API design and authentication to database modeling and access control with a strong focus on production-oriented code. I enjoy solving challenging problems (LeetCode Knight) and am actively seeking backend / SDE roles where I can contribute to scalable systems and grow under strong engineering mentorship.
