Who I Am

Driven by code,
purpose & vision

I'm Dineth Wijesooriya — a software engineering undergraduate simultaneously enrolled at Birmingham City University (UK) and JIAT Sri Lanka, building a career at the frontier of software architecture, AI, and business strategy.

I think in systems, build with precision, and lead with conviction. As Founder & CEO of ByteArrays, I turn ambitious ideas into engineered reality — delivering web & mobile apps, AI solutions, and SaaS products for modern businesses.

"Engineering the future, one byte at a time — where technical excellence meets human purpose."

Currently on a research track toward an MPhil-to-PhD pathway in advanced computing systems — driven by the belief that the deepest impact comes from pushing the boundaries of what's technically possible.
