INDEPENDENT SYSTEMS ARCHITECT • BERUWALA, KALUTARA, LK

Creative by nature.
Engineer by design.

I'm Sayuru — known online as Gaara and X Gaara Dev — working at the intersection of creative thinking and systems technology. Based in Beruwala, Kalutara, I am the Founder of PRRX Cooperation and Co-Founder of PRRX.

Driven by obsessive attention to runtime performance, I engineer ultra-responsive native desktop applications, resilient distributed backends, and sleek modern dark interfaces. My focus is delivering production-grade systems that pair high concurrency and zero-downtime fault tolerance with refined aesthetic craftsmanship.
