What I'm looking for

I'm looking to lead or contribute hands-on to Java, microservices, cloud, fintech, and AI-assisted engineering work where I can improve reliability, automation, delivery speed, and technical quality.

I've delivered enterprise-scale applications for INFOYA, M2P Fintech, Infosys, Swirepay, Syntel, CSC, Verizon, and Sify across fintech, payments, telecom, and networking.

At Swirepay, I built and optimized Spring Boot, Kafka, and Docker microservices supporting 50K+ monthly transactions, 3× user growth, and 99.9% uptime. I improved releases from monthly to weekly through CI/CD and reduced manual regression by about 70% through automation.

I'm hands-on with Java, Spring Boot, AWS, Kubernetes, APIs, testing, observability, and AI-assisted engineering. I also lead teams, document architecture and operations, and focus on clean code, production reliability, and measurable delivery outcomes.
