May you correct my cv, please?

"Collaboration as secretary" is not worded correctly for an English CV. You need to put "Secretary" alone. Or "Personal Secretary" if you were the secretary of only one person. Also, instead of putting "Relationships with clients" you should put, ""Maintaining relationships with clients" Another point is that "Competences" sounds odd....you just need to put "Additional skills" Later though, when you say "Competent with windows and internet" that is fine....it's just "Competences" that is wrong.
