I build software
that makes work
feel simpler.
I’m Md. Mahfuzur Rahman — a software developer working across backend systems, full-stack web apps and mobile products. My recent work includes Spring Boot + PostgreSQL, Node.js + MongoDB, and Flutter.

A few projects that show how I think and build: data models, APIs, authentication, responsive interfaces and useful product flows.

What I work with
A practical
engineering toolkit.
I choose tools around the problem. My strongest proof comes from working projects: a secured Spring application backed by PostgreSQL, a Node and MongoDB exam platform, location-aware Flutter apps and small ML products.

ROLE-BASED ACCESS & CLASSIC CRYPTOGRAPHY LABSAbout
Curious about the
whole system.
I enjoy moving between the data model, the API and the interface until they work together as one clear experience.
I’m studying Computer Science and Engineering at Chittagong University of Engineering & Technology (CUET). Alongside my studies, I’ve built projects in full-stack development, mobile apps, machine learning and information security.
Recently, I’ve been building Java backends with Spring Boot, PostgreSQL, Spring Security and Flyway. I also work with the JavaScript stack and Flutter, and I’m comfortable learning a new tool when a project needs it.
I value clear code, thoughtful product decisions and honest technical claims. I’m looking for opportunities to contribute to a collaborative engineering team and keep growing.
