An interesting pattern I noticed while exploring the deployment process at GitLab was the use of pgrep to perform healthchecks in the Dockerfile or even in Kubernetes (technically you could).

The way ruby is written also involves patching and overriding gem functions/methods. After much frustration in trying to navigate the monstrous monorepo, I gave up and tried Rubymine.

On my last day at Viki, I bought a cup of ice latte from the very cafe where my director spoke to me and tried to find out which team I would have fit best in.

However, I politely declined as I preferred to build up “proper” foundation as an SWE by building components of a distributed system....
