Senior software engineer building scalable backend payments platforms with Java, Spring Boot, and Kafka.

What I'm looking for

I’m looking for a role where I can design and scale reliable backend payments systems—owning system design, TPS control, and microservices performance—while collaborating to integrate secure APIs and maintain compliance.

I’m an experienced Senior Software Engineer with 7+ years building scalable backend systems using Java, Spring Boot, and microservices. I currently work at HCL Technologies at Mastercard in the payments domain, focused on tokenization and consumer digital payments.

I’ve designed and delivered a platform handling 500K+ tokenized transactions daily. I define low-level design and technical specifications, then optimize backend performance and throughput using multithreading and Kafka-based asynchronous messaging—improving TPS by 30%.

I’m strong in system design and reliability under peak load, including TPS control mechanisms to maintain stability. I use proven design patterns like Strategy, Builder, and Visitor to keep systems modular, extensible, and maintainable.

Across teams, I integrate secure APIs and help maintain PCI-DSS compliance. I also contribute to modernization work, including migrating legacy monoliths to Spring Boot microservices, improving code quality, and strengthening CI/CD with Jenkins.
