Now

Updated August 2026

What I’m focused on at this point in my life.

  • Closed out two years as IT Director at De Stijl Technology Network: two engineering teams across APAC, with PFun Store and DxSxT Network in production.
  • Preparing to represent Hong Kong at the AWS AI League Global Championship Grand Finale at re:Invent, now under four months away: refining the winning system’s Bedrock AgentCore supervisor routing, deterministic Lambda tools, specialist sub-agents, memory, and guardrails ahead of the live final in Las Vegas (Nov 30 to Dec 4, 2026).
  • Writing more: aiming for one solid engineering post a month on the blog.
