Crafting scalable full-stack applications with modern JavaScript.Software Engineer at Synergy Information Systems, building live SaaS platforms used by real businesses every day.
// ABOUT ME
Who I Am
I'm a Full Stack Software Engineer based in Sri Lanka, specialising in the JavaScript ecosystem — React, Next.js, Node.js, TypeScript, and MongoDB. I graduated from SLIIT with a BSc in Information Technology specialising in Software Engineering, where I built a strong foundation in scalable system design.
Currently I work as a Software Engineer at Synergy Information Systems, where I design and ship full-stack features across multiple modules of a live SaaS monitoring platform. I take full ownership from requirements through to deployment and post-release support.
Alongside my full-time role I deliver client projects — I've independently built two full production platforms, both live and actively used. I care about clean code, real-world impact, and building things that work at scale.
