Crafting
intelligent
systems.
I am Sandun Gunathilaka, a Full Stack Software Engineer and Undergraduate Student with a passion for building high-performance, agentic-first applications. My work sits at the intersection of robust backend architecture and precision UI/UX design. I specialize in Python, Next.js, FastAPI, and PostgreSQL, focusing on creating scalable systems that solve complex problems with clean, efficient code.

Engineer.
Builder.
Strategist.
I'm a full-stack software engineer and Computer Science student at Cardiff Metropolitan University, based in Colombo, Sri Lanka. I build complete digital products end-to-end — from architecture through production deployment — with obsessive attention to craft.
From AI-powered platforms to e-commerce engines, I operate across the full stack: designing systems, shipping features, and always thinking in products. My focus lies at the intersection of robust backend logic and highly aesthetic frontends.
Things I've
Built.
The Stack.
Let's build
something remarkable.
Open to staff-eng collaborations, full-stack contracts, and ambitious product builds. If you're shipping something that demands craft, I'd love to hear about it.
