About Roshan Sahu
Java backend engineer with 4+ years specialising in Spring Boot microservices, distributed systems, and security hardening — across the full backend lifecycle: feature delivery, migration ownership, and deep debugging under production pressure.At Cognizant, I was core team on a 50+ repository Java 8→21 / Spring Boot 2.x→3.x modernisation. I owned Hibernate 6.x migration, Spring Security filter chain rewrites, Infinispan distributed cache recovery (10M+ cached records, 35% query latency reduction), and 150+ Snyk/OWASP vulnerability remediations — zero production incidents across all environments.Outside work, I\'m building Nivesh Bank — a personal fintech microservices platform (Java 21, Spring Boot 3.x, PostgreSQL, Docker, Gradle) covering Auth, Customer, Account, and Transaction services end-to-end — to go deeper on system design, JWT security, and distributed patterns.
