Hi,
updating a pinned post. I'm a senior developer living near Barcelona, Spain. I use Scala, Typescript, Go, Rust, and hopefully Unison soon.
Occasionally, I post things, but I'm more of a lurker. I won't spam your timeline. I also blog at my domain (see handle).
Glad to be here!

The Planning Game in XP has a rule: if Johnny reckons he can do it quicker than Jane, then Johnny just volunteered to do it.
If your CEO/CTO/Head of Engineering comes back to the office on Monday and says "2 weeks?! I could do it in 2 hours using Cursor!", hand them the keyboard and wish them luck.
