tl;dr - I gave two short talks to different audiences on awesome things you can do with Postgres and how you can use containers with GitLab. You can find all of thses on my talk repo or read them below. I recently gave a couple talks, one at the Tokyo Tech Meetup and another at the Gitlab JP (this one is in japanese, so you may need to bone up on your 日本語) which I thought a wider audience might find interesting.
