Noida, Uttar Pradesh, India
Senior Java Developer / Technical Analyst with 8+ years of experience building scalable, high‑performance backend systems using Java, Spring Boot and microservices architectures. I have delivered complex projects across airlines, automotive and semiconductor domains, with a strong focus on cloud‑native design, reliability and performance. Core expertise includes Java (Core & Advanced), Spring Boot, Spring MVC, Hibernate/JPA, GRPC, REST APIs, Kafka/Google Pub/Sub, Redis, MongoDB, MySQL and Oracle. I work extensively on GCP (GKE, Datastore, Pub/Sub) and AWS, designing and deploying microservices on Kubernetes using Docker, Terraform and CI/CD pipelines. Key achievements: Offloaded a legacy mainframe airline reservation system to modern Java Spring Boot microservices on GCP, improving scalability and reducing infrastructure cost. Built high‑volume GRPC and REST services with sub‑millisecond latency for flight booking and airline crew scheduling. Implemented SAGA pattern for distributed transactions and migrated critical workloads to GKE. Delivered automobile import/export tracking and supply‑chain solutions for Toyota, and an NFT marketplace platform using microservices and MongoDB on AWS. I enjoy reverse‑engineering legacy systems, driving root‑cause analysis in production, and mentoring teams on clean code, performance tuning and microservices best practices. I am currently looking for senior backend / Java microservices roles where I can contribute to cloud‑native, mission‑critical platforms.
