ARTIFICIAL INTELLIGENCE · CYBERSECURITY · SOCIAL IMPACT

Building intelligence at the edge of human impact.

I engineer production-grade AI systems, edge computer vision pipelines, and cryptographic mobile applications—translating complex human service needs into resilient, privacy-preserving technology.

01 // Background & Philosophy

Bridging computing rigor with human welfare.

Two decades spent deploying frontline digital transformations for 4,000+ staff and diverse community cohorts.

I am a technology leader with over twenty years of deep, dedicated experience across the social services sector. My career is defined by a unique dual foundation: holding formal degrees in both Computing Science (1st Class Honours) and Social Work and Social Sciences (mgt) from universities in Hong Kong and UK. Over the years, I have architected and deployed enterprise case information systems, biometric credential managers, augmented reality platforms, and high-throughput computer vision workstations.

Rather than pursuing innovation in a vacuum, I specialize in translating high-stakes human challenges into production-grade AI solutions. Currently pursuing a Master in Artificial Intelligence at the University of Leeds, my technical focus centers on (a privacy-preserving dual-LLM candidate screening engine with zero PII leakage), (a multi-agent system decoupling exact JUPAS admission score math from empathetic Cantonese counseling), the (an enterprise hybrid RAG engine delivering clause-grounded statutory guidance across complex welfare funding manuals), and the (an archival RAG interactive docent serving eight decades of heritage with multilingual kiosk narration and strict curatorial guardrails).

01. PRIVACY AT THE PERIMETER

Strict zero-PII cloud egress. Sensitive beneficiary records and candidate evaluations are processed strictly on local hardware or client devices.

02. SOCIAL MISSION EQUALITY

Harnessing frontier models to actively bridge the digital divide for low-income families and non-profit operations rather than commercial lock-in.
