I build scalable Java microservices, APIs, and distributed systems for high-availability platforms.
IndiaWhat I'm looking for
At GE Healthcare, I build and modernize Java and Spring Boot backend services, resolving critical production defects and improving the reliability of real-time data pipelines.
I've reduced production downtime by 40% through Jenkins, Docker, and Blue/Green deployments, increased peak-load throughput by 40% through concurrency refactoring, and lowered REST API latency by 15% while migrating core modules from Java 8 to Java 17. I also strengthen platform security through STIG controls, FIPS-compliant fixes, penetration testing, and OWASP-aligned Spring Security remediation.
Earlier, I developed a full-stack Q&A platform at Desi QnA and improved page load times by 30% through SQL optimization and indexing. I enjoy building cloud-native, scalable systems with microservices, REST APIs, Docker, Kubernetes, AWS, and Azure.
