About

Backend Software Engineer with 3 years of experience building Java/Spring Boot systems for high-volume healthcare data — REST APIs, microservices, and data pipelines processing insurance enrollment, membership, and billing information at scale. I work across the full backend lifecycle: designing layered architecture (Controller–Service–Repository), building and testing RESTful APIs, writing efficient SQL, and keeping production systems reliable — including hands-on log analysis, root-cause debugging, and CI/CD pipeline ownership. Recent focus: applying SOLID principles and clean architecture to microservices, and exploring how GenAI tooling (Claude, GitHub Copilot) fits into modern backend development workflows. Currently based in Coimbatore, India — open to relocating to Singapore or the UAE for backend/Java engineering roles, sponsorship required. Reach out if you're hiring backend engineers who can own a system end-to-end.
