"Expertise" field choices

[PetrusM]

🙋 Feature request 🙏

📌 Context

When listing my missions, for the field "Expertise", as a developer I had the choice between "Mobile App Development", "Front end", "Back end", "Full stack", "DevOps".
I develop thick clients (including desktop), and low-level libraries (eg. serial port, communication protocol,...). I do not think any choice suits what I do : they only describe web and mobile development.
I checked "back end", but I am not satisfied...

🌱 How you would solve it

I think some choices could be added, like "Low level development", "Thick client development", and also "Information systems architecture", or even "Critical systems development" (eg. for avionics,...).
