Chamindu Hansana — Full-Stack Developer

Who I Am

Turning curiosity
into code

NSBM

Green Univ.

Hi, I'm Chamindu Hansana — a Computer Science undergraduate at NSBM Green University (GPA 3.84/4.00), focused on full-stack web and mobile development.

I build applications with React, Next.js, TypeScript, ASP.NET Core and Spring Boot, backed by PostgreSQL and MySQL, and I've deployed a full-stack student marketplace to production on Vercel.

Secure authentication runs through my work: JWT-based login, role-based access control, password hashing and protected routes across several projects. I'm also learning AWS and DevOps fundamentals through short courses.

I've worked in student teams using GitHub branches and pull requests, practising clean code and version control — and I'm looking for an internship where I can grow as a software engineer.
