Mahamudul Hasan

I’m a Bachelor of Computer Science student with a CGPA of 3.78, currently building real-world web applications while staying active in competitive programming. I enjoy turning ideas into clean, maintainable user experiences.

In my AMERNStack online grocery delivery web engineering application, users can order various groceries, search products, view details, and review previous orders. I developed the frontend with React and Tailwind CSS, and built the backend with Node.js and Express.js, using MongoDB for the database and JWT for authentication. Cloudinary and image upload support helped me keep product media organized and scalable.

I also bring a strong algorithmic mindset from competitive programming. I’ve reached a MaxRating of 1559 on Codeforces (Specialist) and solved 180+ problems on LeetCode (180+), with multiple contest rankings across Codechef and university programming competitions.

As a Teaching Assistant for Competitive Programming, I supported the course teacher by reviewing and evaluating student code, and mentored learners on daily problem-solving and time management. I’m motivated by feedback-driven improvement and consistently ship work that’s reliable, readable, and ready to be used.
