System Design

What I did with it

  • I was responsible for architecture and system design most of my professional life
  • made monoliths
  • made microservices
  • made hybrids

What I think

Any architecture pattern as strong as a team that implements it.

I am big fan of microkernels, but yet to see a team that can pull it off without pain.
