About

With a B.Tech in Computer Science from Haldia Institute of Technology (CGPA 9.2), I’m now a Software Development Engineer at Cleartrip (AE) in Bangalore. In this role, I’ve engineered and integrated Flyadeal airline APIs end‑to‑end—from search through booking—while driving performance optimizations that cut API latency by 15% and resolving over five critical production issues to ensure seamless user experiences. Before Cleartrip, I was a Software Development Engineer at Trustt (formerly Novopay), where I built a multithreaded asynchronous service system for HDFC—boosting throughput by 34.3% for 80,000+ users—and implemented an Apache Kafka–driven agent‑onboarding pipeline. I also led the migration of key microservices from Java 11 to Java 17, resolved 40+ production bugs, and collaborated cross‑functionally to maintain >80% test coverage with SonarQube‑compliant code. Passionate about crafting scalable backend architectures, I specialize in Java, Spring Boot, microservices, SQL, Apache Kafka, and Redis. I thrive on continuous learning and complex challenges, and my long‑term goal is to evolve into a versatile engineer who delivers high‑impact, user‑centric solutions.
