About Me

Tanvir Islam profile picture

I am a passionate Competitive Programmer with a strong foundation in algorithms, data structures, and problem-solving. I have solved 1000+ problems across various online judges including Codeforces, AtCoder, CodeChef, and more — consistently pushing my limits to sharpen my analytical thinking.

With a deep love for algorithmic challenges, I thrive on turning complex problems into elegant solutions. Whether it’s dynamic programming, graph theory, or number theory, I enjoy every dimension of competitive programming.

Currently pursuing B.Sc. in Computer Science & Engineering at Patuakhali Science and Technology University, I blend academic knowledge with real-world problem-solving skills to build efficient, optimized solutions.
