I'm working with PHP for a long time now back from PHP 3 and Python (like from 1 yr later). I think I can do what I have to with these. In the last 3 yrs I tried to pick up and mastering Go.
Right today I try to do everything with Docker containers and if suitable with Kubernetes, but sometimes it's not accessible so, I do what I can.
As I always looking for more and more to learn and extend my knowledge widely, now I try to learn and get to an acceptable level Haskell. For now I like it.
Client projects, mostly improving and extending the hosting platform for Acquia and help to create for Cheppers. Meanwhile I have my own infrastructure with a few hundred non-profit/bands/groups sites on Kubernetes. That's basically all my time.
I'm not sure I'm available, but if I do... Mostly discussions about a problem, teaching, theoretically problem-solving, consulting. I'm not looking for a job, but if you have a pet-project (it can bigger than a pet) I'm happy to help with specified problems even with coding.
