Erasmus in Germany + Summer internship

So I kind of had a life plan going:

• This summer I am doing an fellowship in Bulgaria.
• 2026/2027: Erasmus full-year at TUM in Munich.
• Summer 2027: Internship in Quant (in the unlikely case I get one) or a Systems-related job. Mainly to get an idea of what I'd like in the future.
• 2027/2028: Last year of university.
• 2028/2029: Graduate role at some foreign company, get some savings.
• After that: Consider a Master's or keeping working.

But now reality is starting to set in. TUM's exams end really late (end of July or beginning of August) and I start my last year in September, so I don't really know what my realistic options are. Has anyone been in a similar situation? My Summer Semester is going to be rather chill so maybe I can do something during?

Is there any kind of opportunity (maybe something in Munich's own ecosystem) that is compatible or should I just enjoy my summer?

I know this is what I get for doing an Erasmus, but who knows, maybe there is a middle point between regular internships and a personal-project summer. Any advice is welcome! Thanks!
