Products taken from concept to market. Some already shipping.
I'm a Senior Computer Engineer with an advanced degree in Computer Science & Engineering and more than 25 years of experience — spanning chip-level design, embedded and real-time systems, enterprise software, web and mobile platforms, cloud architecture, and today's AI-driven applications.
I've worked with Fortune 1000 clients across payments, banking, retail, telecom, medical, networking, and industrial sectors. Today I consult, teach, lead teams, and invent — helping people and organizations build systems that actually ship. I'm bilingual in English and Mandarin Chinese.

From idea to market — and everything in between
Make the right decisions before code is written — system design, technology selection, and scalability planning.
Get stuck projects moving again. I lead engineering teams to deliver complex work — on time and on target.
Keep live systems running — incident response, root cause analysis, performance tuning, and on-call coverage.
Systems and products delivered — from national payment networks to world-first inventions
Payment systems and gateways deployed across multiple cities and regions in China, processing online financial transactions at scale.
Regional and international financial network systems for US banking and payment clients, handling high-volume, mission-critical transactions.
Developed Erenna for medical research and biomarker analysis, and Clarity — a clinical analyzer for high-sensitivity in vitro diagnostics.
Engineered a 2nd-generation intrusion detection and prevention system for enterprise network security and real-time threat monitoring.
An energy storage system for efficient power management and emergency backup, combining embedded control with IoT monitoring.
Invented the world's first smart handwashing monitor — tracking restaurant employee behavior and hygiene compliance to improve health environments.
