AboutMe
I'm Suboth — 22, born and based in Sri Lanka, and I've been shipping production software since I was 16. That early start is the whole point: five years on I've architected high-performance cross-platform systems for mobile, desktop, and web, and today I lead a team of 16 building scalable B2B/B2C platforms and AI-integrated tools with Next.js, React Native, and Azure.
