Skills⌗

During the last >15 years, I encountered a range of different engineering and team problems; leading to a lot of research, experiment, test, delivery from the lowest levels of network and systems to orchestration of high scale infrastructure, performant and understandable CI / CD tooling, automation, data modeling…

I think that with seniority, the point is to clearly identify the problem, the time frame and the complexity; expressively not focusing on the tools at first.

However the market is so focused on the tools x year of usage, that below is an overview of technologies seen during that time. It is not exhaustive and the table representation really bad for now :)
