Given that you're studying, apply to any software company as a "Werkstudent". You can work up to 40 hours per week during periods without lectures, up to 20 hours otherwise. The benefits of that versus normal employment are reduced taxes for you and the company. Companies usually do that and also invest in upskilling you in the hope of being able to hire you later. Look up different companies located close to you and just apply.

Source: I worked like that for a small webdev company and than a rather big company til 2021.

Out of curiosity, what license do need?

If the course of study isn't fixed, yet, you could look for a "Duales Studium" and ask the company to start earlier/asap - most likely they'll accept. But Werkstudent is probably better

Idk how schools are outside of US but for here, it is very common for schools to hold career fairs where local companies can go to scope out students by their area of study. I would look into this to see if there is anything similar where you are. I was able to do this and get hired as intern while I completed university, they very flexible with my school schedule and I was able to build up 3 years of experience before I even graduated and once I did graduate I was able to transition to full time almost immediately.

Can't you just look for a hiwi job? Or are you looking for full-time?
