Java Backend Developer @ TCS | Building RTGS Payment Microservices with Kafka · Spring Boot · AWS | BFSI & FinTech | TCS Gems Award

About

I am a Backend Java Developer with 4+ years of experience building high-availability, SLA-bound payment systems in BFSI environments. I specialize in designing distributed, event-driven microservices using Java 8/17, Spring Boot, and Apache Kafka. Currently working on ISO 20022/SWIFT RTGS payment platforms, I design ingestion, validation, transformation, and workflow orchestration services that handle financial transactions where consistency, ordering, and zero data loss are critical. My core strengths include: • Architecting Kafka-based streaming systems with optimized partitioning, idempotent processing strategies, acks=all producers, controlled offset commits, and duplicate prevention via database constraints • Designing fault-tolerant microservices with retry, backoff, and Dead Letter Topic (DLT) mechanisms to prevent cascading failures • Implementing transactional consistency across distributed systems • Performance tuning through parallel consumption, batch processing, caching, and indexing strategies • Building configuration-driven rule engines for multi-country payment workflows • Containerized deployments using Docker and Kubernetes Previously at Intellect Design Arena, I worked on trade execution and onboarding systems, improving trade processing latency by 30% through asynchronous processing and optimized database strategies. I also implemented secure JWT-based authentication and addressed VAPT findings to strengthen API security. I am passionate about building financial-grade systems where correctness, ordering, resilience, and throughput are non-negotiable. I continuously deepen my understanding of distributed systems, Kafka internals, concurrency, and scalable backend architecture to prepare for high-impact product engineering roles.
