Backend systems, cloud deployment, and production-ready software.
I’m Vivek Kumar, a Backend Developer focused on building scalable APIs, enterprise-grade applications, and cloud-hosted solutions using Java, Spring Boot, SQL, and AWS.
Building reliable backend systems with real-world impact
A recruiter-first overview of my experience, engineering focus, and deployment capabilities.
I’m a software engineer with hands-on experience in backend development, SQL optimization, API design, and cloud deployment. My work focuses on building production-ready applications that are stable, scalable, and easy to maintain.
At TCS, I work on enterprise financial systems using Java, Spring Boot, and SQL. I’ve also deployed independent projects on AWS EC2 with Nginx, Gunicorn, and domain mapping — giving me both product development and infrastructure exposure.
