Können Sie bitte meinen Lebenslauf für den Schweizer Markt überprüfen?

Way too bloated.

No one’s gonna read that. It is also too dense. Remove all of the unnecessary information and use shorter sentences. Keep it lean. Add more space and make it readable.

Ask yourself do you want to read it if you are not forced too? If they do not want to read it then they won’t. They have enough other potential candidates. So you’ll just land on the pile.

Make the most important information bold. This helps draw attention to the things you want them to see and away from other less important skills. For example make specific skill bold in the experiences in a job.

Lose the professional summary. The Cv should be the summary. If your summary needs a summary then you know you are doing something wrong.

Again don’t use long sentences. And describe each activity of a job in one or two sentences or even better just keywords.

It is also kinda ugly but is probably mostly because of all the bloat.

Reserve all the removed stuff for the cover letter if it applies to the job that you are applying for.

Sorry for the rather harsh feedback but this is my honest opinion.

I doubt this is only valid for swiss market.
