About Me

I'm a full-stack developer and educator from Sri Lanka, currently pursuing a BSc in Computer Science & Engineering at the University of Moratuwa. I specialize in building high-performance, serverless web applications using Python, TypeScript, and Golang. My experience includes developing the NJPAPER.LK exam platform (serving 3,000+ monthly users) and actively maintaining over 8 open-source projects. Beyond coding, I'm passionate about tech-driven education, having co-led a large-scale physics instructing team and conducted numerous seminars for A/L and O/L students.
