The Tech Evolution

My career began at the physical layer of the OSI model — literally climbing towers to maintain microwave links for PCCW, where I maintained 99.9% uptime for ground-to-air communications. From there I deliberately climbed the abstraction stack: embedded firmware, device drivers, application servers, distributed systems, cloud orchestration. Each layer taught me the constraints the layer above tends to ignore. Today I can trace a production incident from a Kubernetes pod restart all the way down to a thermal throttle on an edge device — because I have worked at every layer in between.

Scientific Foundation

Research Assistant (Physics)

University of York

Co-authored a paper on complex system troubleshooting. This experience instilled a rigorous scientific methodology for data modeling and analytical problem-solving that I apply to software architecture today.
