I tried popular platforms (up-Work etc.) but the process to be admitted and start getting gigs is long/complex and a bit foreign to me.
I just recently finished teaching two bootcamps in Germany in Full-Stack Web Dev. I am also a Certified Engineer (Italy), but unsure what I could do remotely in this regard.
Here are some things I think I can contribute to:
1) Front-end specifically React, but would not disdain Vue. Good to advanced skills here.
2) Apps Script / Google Suite coding and automation. Good to advanced skills here
3) Back-end, specifically Node/Express/Mongo. Good to advanced skills here, but can do basic SQL methods.
4) Some Python/Panda but very basic.
5) Remote team management / project management. Good to advanced skills here.
Also, if others are in my situation and affected by the travel ban, please come forward. It's always good to band together.
