About

Backend Engineer passionate about building secure, scalable systems that solve real-world problems. Currently working as a System Engineer at Tata Consultancy Services, where I engineer and deploy security-critical features for Nokia's Identity & Access Management platform (NIAM) — serving 100+ enterprise clients globally. What I bring to the table: • 5+ security features built & shipped — including password rotation and privilege escalation modules • 50+ production bugs resolved across customer-facing environments • 30% reduction in feature deployment time through code optimization and streamlined CI/CD • 60% faster deployment cycles achieved during Nokia internship via API performance improvements Tech Stack: • Backend: Java · Spring Boot · Core Java · REST APIs · Spring Framework • Databases: SQL · PL-SQL · MariaDB • Cloud: GCP · AWS · Nokia Cloud Services • Other: Git · Power BI · Machine Learning · ReactJS · Python What sets me apart: I don't just write code — I build systems that are robust, testable, and production-ready. I've worked at the intersection of backend engineering and cybersecurity, giving me a unique edge in identity management, API security, and enterprise-grade deployment. Currently deepening expertise in: → Distributed Systems & Scalable Architecture → DSA for system design interviews → Machine Learning & AI → B.E.
