About

Software Developer with 2.8+ years of experience building scalable backend services using Java, Spring Boot, and REST APIs. Currently at Tata Consultancy Services, contributing to production systems for HDFC Life Insurance — REST API development, third-party integrations, and SQL performance tuning. Improved API response times by ~35% through query optimization and elimination of redundant database calls on a high-traffic production system. I've taken end-to-end ownership of product features, collaborated with cross-functional teams (frontend, QA) in Agile environments, and handled L2/L3 production incident triage and root-cause analysis. My work follows Controller-Service-Repository architecture with SOLID principles, focused on writing clean, testable, maintainable code. Tech: Java, Spring Boot, Spring Data JPA, MySQL, REST APIs, Git, Maven, Docker (basics). B.Tech in Electrical and Electronics Engineering, MVGR College of Engineering.

Work experience

Software Developer at Tata Consultancy Services, Oct 2023 - Present · 2 y 11 mo, Bengaluru, Karnataka, India, Software Developer with 2.11 years of experience designing and building scalable backend services using Java and Spring Boot. Working on production systems for HDFC Life Insurance, focused on REST API development, third-party integrations, SQL performance tuning, and maintainable backend architecture. I integrate and consume third-party REST APIs within Spring Boot services to support insurance policy and claims workflows, handling error cases and retries to ensure reliable data flow between systems. I've taken end-to-end ownership of multiple product features, from writing backend business logic through wiring up UI integration, which has reduced cross-team handoff friction. On the performance side, I optimized SQL queries and eliminated redundant database calls, improving API response times by roughly 35% on a high-traffic production system. I also integrated an external SMS gateway to deliver real-time policy and claim status notifications to users. My work follows a Controller-Service-Repository layered architecture with SOLID principles, keeping business logic decoupled from data access and improving testability and maintainability. I regularly handle L2/L3 production incidents, performing root-cause analysis and deploying fixes with minimal downtime on a live insurance system. I collaborate closely with frontend, QA teams in Agile to deliver features end-to-end, and actively participate in sprint planning and code reviews. Tech stack: Core Java, Spring Boot, Spring Data JPA, RESTful APIs, JDBC, MySQL, Git, Maven, Docker (basics).
