I wrote about something very close to my heart: how to make ALL the tests async in @elixirlang. Enjoy! 🏎️.

It can be hard to keep tests asynchronous as Elixir applications grow in size and complexity. Let's see why, and explore fixes.

NimbleOwnership may not take bribes, but it certainly knows who your father is.

Tomorrow I start as a platform engineer at @knocklabs. Excited? Yeah, but it's sort of like coming home? I know I will have the BEST time there. I think we were all meant to be. 🥰.

Fun fact, you can put plausible analytics on your hexdocs. This is, for @AshFramework, our best indication of adoption/trends. We can see the most used packages and documentation pages easily, and gauge overall usage 🚀 . #myelixirstatus

Big thanks to the @elixirlang community, because quite a few people reached out 🙃. I haven't settled on anything yet though, so if you're looking for someone please feel free to DM. Btw, I’m looking for a full-time job, I don't do much contracting 🙈.
So. my contract gigs will end in a few days. I’m now looking for a job! 🤓. - Principal engineer, backend/systems/arch focus.- Fully remote, flexible hours (hard to find ppl in the same tz), pref async work.- @elixirlang is def my strength, but I just love doing stuff.
