About

Building software that just works

I am a software architect and website engineer based in Hong Kong SAR, with over 20 years of experience in the IT industry. I specialize in web project management, system design and programming − from real-time financial trading systems to public-transport data apps used by thousands daily.

My work spans the full stack: designing resilient backend architecture, wiring up market-data feeds, and shipping polished native Android apps that people rely on every commute.
