Building skills through real projects.

I'm a Computer Science undergraduate at Sabaragamuwa University of Sri Lanka. My main interest is building practical software systems that solve real problems.

My current development work spans React, Flutter, Firebase, Node.js, APIs and databases. Alongside application development, I'm deliberately building a stronger foundation in Linux, Docker, CI/CD, cloud platforms and DevOps practices.

Current focus

→ Full-stack application development
→ Cloud & DevOps fundamentals
→ CI/CD and deployment automation
→ API design and backend systems
→ Writing maintainable, documented code
