About & resume
About me
I’m a full-stack developer from Colombo, Sri Lanka, currently finishing up my degree in IT with a focus on AI.
For the past six years, I’ve been building real-world web, mobile, and AI apps for clients around the globe. Most of my work revolves around Python and Node.js on the backend, paired with React, Next.js, and Flutter on the frontend. I genuinely care about the small details that make software great: fast load times, clean code, reliable databases, and interfaces that feel effortless to use.
When I’m not coding, you’ll probably find me tinkering with machine learning, tweaking design details, or automating little things in my daily routine just for fun.
