@manishjha2

Java Full Stack Developer at Tata Consultancy Services who cut API latency by 25–30% and built reusable authentication integration.

At Tata Consultancy Services, I design, develop, and maintain Java backend services using Spring Boot, Hibernate/JPA, and microservices. I developed a reusable authentication integration component that eliminated manual credential syncing across 8+ enterprise applications.

I also reduced API latency by 25–30% through query optimization, caching, and backend refactoring, and developed a secure bulk-upload solution that reduced manual effort by over 80 hours. On my SplitShare project, I built a full-stack expense management application with Spring Boot and React.
