Tools and technologies
Below is a partial list of tools, processes, and practices that I have used in companies or private projects. Some are familiar to me, while others less so. I currently use some and not others temporarily.
In my opinion, such lists quickly become outdated, and a good engineer can easily master any application tool if the principles of its operation are clear to him/her.
It’s better to read about the tasks being solved, send a DM or schedule a meeting with me to form your own impression.
