About Me

I'm Dilip Kumar, a B.Tech Computer Science student at Lovely Professional University with a relentless passion for solving problems and building products that matter.

With 1000+ DSA problems solved across LeetCode, Codeforces, and CodeChef, I thrive in competitive programming and algorithmic challenges. I bring the same intensity to full-stack development — crafting secure, optimized, and scalable web applications.

When I'm not coding, I'm diving deep into cybersecurity and networking, exploring everything from ethical hacking to network protocols.

🚀 Currently learning: System Design, Low Level Design & Spring Boot — building towards becoming a well-rounded Software Engineer.
