About Me

Full-Stack Software & IoT Developer.

I am an undergraduate student at the University of Moratuwa pursuing a Bachelor of Science Honours in Information Technology. My passion for technology began with a deep curiosity for how software and hardware interact, and I have been building live systems ever since.Currently, I program in Next.js, PHP, SQL, C, and C++ for microcontrollers.

As a university student and solo developer, I have engineered a wide breadth of production-ready projects,including comprehensive hotel management system and a biometric IoT lab access ecosystem—a multi-door RFID and biometric security system, complete with a custom web interface, that is actively used in two university laboratories.

Beyond my core academics, I manage my own cloud infrastructure using Green Cloud and Docker, orchestrate automated CI/CD pipelines via GitHub Actions,Ultimately, my core interests lie in building complete software products and engineering practical, efficient solutions to complex real-world problems.
