What I'm looking for

I am seeking backend or platform roles where I can build scalable Java microservices, improve system reliability, and work collaboratively in Agile teams to deliver production-grade APIs and services.

I am a backend-focused software engineer with hands-on experience building scalable microservices and APIs using Java and Spring. I design robust services that emphasize performance, security, and testability.

At EdgeVerve Systems I developed backend services for the PolarisEdge platform with Spring Boot and WebFlux, led a migration from Spring MVC to Spring Boot, and achieved 94% integration test coverage across critical components.

I improved system reliability and operational efficiency by integrating Liquibase for automated DB deployments, optimizing SQL performance, and enhancing API security with Spring Security Filters. I also collaborate closely with product and QA teams in Agile environments.

I enjoy solving algorithmic problems (300+ solved across platforms), building end-to-end e-commerce microservices with Kafka, Eureka, JWT auth, and working with both SQL and NoSQL databases to deliver modular, maintainable systems.
