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
MSc Electronic and Information Engineering
City University of Hong Kong (2014 — 2016)
Graduate specialisation in digital signal processing, communication systems, and embedded control. Deepened the circuit-level and systems-level thinking that underpins hardware-software integration work today.
BSc Computer Engineering
Open University of Hong Kong (2012 — 2014)
Formal foundations in digital systems, circuit design, and signal processing — the bedrock for later firmware engineering and hardware-software integration work.
Research Attachment (Physics)
University of York (2015)
Co-authored a published paper on magneto-optical detection of spin accumulation (Scientific Reports, Nature Publishing Group). Instilled rigorous scientific methodology for data modelling and analytical problem-solving.
