Sudhir Kumar

I’m a detail-oriented Junior Full Stack Developer with hands-on internship experience building, testing, and maintaining scalable software applications. I focus on clean, reusable code, practical troubleshooting, and delivering user-friendly solutions in Agile teams.

During my internship at KodNest Technology, I helped develop and test 15+ RESTful API endpoints using Java and Spring Boot. I also collaborated on mobile-responsive frontend features with React.js, HTML, and CSS—reducing page load times by 25%.

On the backend, I improved performance and reliability by optimizing MySQL schemas and SQL queries, reducing database latency by 45%. I additionally conducted 40+ peer code reviews and applied best practices that resulted in zero security vulnerabilities in final code delivery.

I bring this same analytical mindset to my projects, including an NGO Volunteer Collaboration Portal with Spring Boot, Hibernate, React, and performance gains of 30% after query optimization. I’m now looking to grow as a developer by building secure, well-structured systems and strengthening my impact across full stack delivery.
