For the Python Developer position, I expect a Python >= 3.8 code base.

I'm looking for a team of small to medium size, expecting sensible task requirements and reasonable deadlines. I can also work alone if I'm asked to, but this should be negotiated in advance so we can meet each other's expectations. I also need to clearly understand my future area of responsibility before accepting an offer.

I expect some challenging and non-trivial tasks that would involve some R&D when needed.

Having opportunities to teach and learn would be great as well as I am used to exchanging experience all the time.

I would love to work on distributed messaging (XMPP, matrix.org) or social network (ActivityPub) technologies as I have some interest and hobby-dev experience in them.

Please note that I'm not a full-stack developer, however, I am open to offers that would introduce this responsibility later on, giving me an opportunity to gradually gain the required skills. My current knowledge and experience in JS on front- and backend is rather basic. That means, I am capable of things like developing a simple page with some basic CSS and JS, writing a utility JS program for some infrastructure component, debugging and fixing a broken script on front- or backend, but I have no proper experience in any JS frameworks. If you expect me to do more than this, please let me know so we can discuss it beforehand.
