I'm very open minded to learn and try new stuff. "Learning by doing" is my favourite way of touching new things. And I believe failure is always good, it gets me success.

Highlight At Work(Latest -> Oldest)

• Joined TraceLink PaaS product team (3rd generation platform):

  • Designed and implemented first version Graphql server, along with schema standard and customize directives
  • Designed first version AuthZ service (also being first generation OPA user

• Joined TraceLink ET platform team (2nd generation platform, internal use only):

  • Designed general rate limiter lib for all eng teams (no idea how many of them are still using my lib lol, but it's still a very interesting experience)
  • Built bunch of internal support tools that help TraceLink developers debug their applications on our platform (I really enjoy building these small tools to improve productivity)

• Joined Vecna VPS team (Patient Information System for VA Medical Centers)

P.S. I'm always looking for interesting and challenging side project to work on. Contact me if you need DEV :)

When I'm not in front of a computer screen, I'm probably playing soccer ⚽, taking care of my three chinchillas 🐹🐹🐹 and watching 📺 TV series on Netflix/HBO/Hulu/Amazon Prime.
