Hi, I’m Waruna Wickramasingha

I warmly welcome you to my website. I’m a software engineer from Sri Lanka, currently living in the United Kingdom. I have over a decade of experience designing and developing scalable, high-performance, mission-critical, fault-tolerant, and distributed systems. My work experience spans multiple domains, including scientific computing, artificial intelligence, agentic AI, capital markets, cloud computing, banking, medical systems, and telecommunications, each with its own constraints, risks, and trade-offs.

This website is a collection of technical tutorials and articles written by me that I believe are worth sharing with others. They are inspired by some of the most valuable lessons I’ve learned throughout my technical career, which spans years of building real-world systems.
