These are the technologies that I have experiences, some familiarity or education in. I make this website to track it.
I am not expert on everything in these trees but I do not find any of them to be impossible to master, during my exposures with them.
I understand that there are plenty of gaps in my knowledge, and that's common in technology. It is hard to keep track of it as new things keep coming up.
Most of my works revolved around either the backend or the physical environment, and adapt to what technology the company required.
General problem-solving and adapting to new technology became my strongest skill at this point in time.
All these skills are tools, I generally did not care much about what tool I use as long as it got the job done. That' s why Pythons has so many branches compared to JS and the rest.
These trees are made by Python Networkx Library. JavaScript D3 Library would be a better option for Interactivity, and I may built them with it later.
Right now, I'm learning Django, C# and do more machine-learning with Sklearns.
