About

I’m a Full Stack Software Engineer with 3+ years of experience building enterprise-grade software in the BFSI domain, with a strong focus on scalable backend systems, microservices architecture, and product engineering. Over the last few years, I’ve worked on platforms powering payments, workflow automation, mandate processing, transaction routing, and operational tooling. My recent work includes designing core components for Payment Hub, API Engine, Workflow Engine, and Ticketing platforms used across multiple BFSI clients. One of the most impactful systems I built was a high-throughput transaction processing platform for one of India’s largest NBFCs, capable of processing 40+ crore transactions in under 5 hours while improving performance by 70% over the legacy architecture. I enjoy solving engineering problems around scalability, reliability, automation, and system design. My experience spans Java, Spring Boot, React.js, Kafka, PostgreSQL, Docker, Kubernetes, AWS, and CI/CD pipelines, along with AI-assisted workflows such as OCR-driven document extraction and validation. Alongside the technical stack, I bring hands-on domain experience in NACH, eMandate, ABPS, ISO 20022, CBS integrations, NPCI H2H, reconciliation systems, and financial transaction routing. I’m currently looking to grow in roles where I can combine strong engineering fundamentals, ownership, and product thinking to build scalable systems that solve meaningful business problems.
