🌍 Software Engineer | 💻 Full-Stack Developer | 🧠 AI Enthusiast | 🏆 Competitive Programmer

Once upon a time, a curious boy discovered the magic of problem-solving through C programs on an old laptop.
Fast forward a few years — that same curiosity grew into a passion for technology, algorithms, and building things that matter.

Today, I’m Zahid Hasan Mozumder, a Software Engineer who loves blending creativity and logic to craft meaningful software experiences.

I’ve built RESTful APIs, streamlined integrations for products, orders, and payments, and designed modular database systems using modern technologies like NestJS, Spring Boot, PostgreSQL, and MongoDB.
I’ve also explored secure systems with JWT, OAuth2, and Stripe, and handled real-time communication with WebSockets and Socket.io.

Before this chapter, I honed my frontend skills — bringing life to web interfaces with React, Bootstrap, and TypeScript.
And before that, I shared my love for coding as a Programming Trainer, guiding university freshmen to think logically and fall in love with problem-solving.

I graduated in Computer Science and Engineering from Green University of Bangladesh,
where I didn’t just study — I competed, built, researched, and kept asking why until I found how.

I even co-authored a paper titled

"Optimizing Carboxymethyl Cellulose (CMC) Production: A Metaheuristic Algorithm Approach"
presented at IEEE ICCIT 2024 🔬
(DOI: 10.1109/ICCIT64611.2024.11022351)

Every project I build tells a story — of logic, creativity, and impact.

• 💬 goChat — A real-time chat application with one-to-one and group messaging, powered by React, Spring Boot, and WebSockets (secured with JWT & OAuth2).
• 🌍 Disaster Management System — A role-based web app that helps volunteers and donors collaborate efficiently.
• 🛒 FashiON — A modern e-commerce frontend focusing on responsiveness, speed, and user experience.

Each of these projects taught me something — from scalable backend design to pixel-perfect UI —
and reminded me that great software is both art and engineering.

I believe in writing code that speaks clearly,
systems that scale smoothly,
and designs that feel effortless.

My coding story wouldn’t be complete without the thrill of problem-solving and contests —
where logic meets creativity under pressure ⚡
