Hi, I'm Dimuthu

An Engineer. I architect distributed systems & AI infrastructure that scale to millions. Robot FleetLimbiqTF SandboxKithlyZylobinCard PromotionsDrawPro

I'm currently living in Singapore. I grew up in Sri Lanka and thanks to strong A/L results, I earned a free education at the University of Peradeniya, Faculty of Engineering, where I studied Computer Engineering. My final year research project was on landing a quadcopter on a moving target using computer vision.

During my internship at Wavenet, I built an emergency dispatching application for a security company. That work earned me the Best Industrial Trainee award from the Institution of Engineers Sri Lanka (IESL).

I joined DirectFN and worked on a stock market brokerage application, building backend APIs for financial trading systems.

At Sysco LABS, I led the freight management apps team, developing distributed microservices on AWS with real-time streaming pipelines.

I then joined Bitsmedia and helped them migrate the platform from a cloud function-based setup to a GKE Kubernetes cluster. Along the way, I drove cost reductions in video pipelines and built a new data platform from the ground up.

I'm an active public builder — I share what I learn through writing on Medium and open-source projects on GitHub.
