About me
I'm a full-stack developer who cares about the code I write and the people I build for. Here's a bit about where I came from and what drives the work.
I got into development properly around 2018, studying computer science at the University of Moratuwa and spending every free hour either breaking or fixing things. I was the kind of student who'd stay up until 3 AM figuring out why a query was 200ms slower than it should be. I still am.
After graduation, I spent three years at a product startup in Colombo — building features, debugging production fires, and eventually owning the architecture of a platform that grew to 50k users. That taught me more than any course could: how to make decisions under pressure, how to communicate trade-offs clearly, and how to write code that someone else can actually maintain.
I went freelance because I wanted more variety — and frankly, more ownership over the quality of what I ship. When you're working directly with a founder or a small team, there's nowhere to hide mediocre work. That accountability sharpens you.
I typically work with 2–3 clients at a time. That's deliberate. I'm not trying to build an agency — I'm trying to do focused, high-quality work for people who care about the details.
