Please correct

Hi everyone,

I want to express the next sentence for my cover letter. I have some doubts about ausbauen and about the last sentence.

Wie in meinem Lebenslauf dargestellt, konnte ich mir in den letzten Jahren bei verschiedenen Seminaren, Workshops und Konferenzen durch Präsentationen und Vorträge meine Fähigkeit Sachverhalten darzustellen ausbauen. Meine Diplomarbeit war ein Projekt von der DFG, welche in Verbindung mit verschiedenen Universitäten entwickelt wurde. In den verschiedenen Teams habe ich mich schnell zurechtgefunden.

My attempt is:

As shown in my resume, I was able to extend to me in recent years in various seminars, workshops and conferences through presentations and lectures my ability to present issues. My thesis was a project of the DFG which were developed in connection with different universities. In the teams I've found my way quickly.

In general it is recomended to avoid very long sentences when writing in English.
The attempt to create a literal translation of your German draft might not be the best idea either.
You can use the German draft as a guide towards the content you want to express but more is less helpful.

In recent years I used many opportunities to improve my presentation skills by giving talks and presentations on various topics (related to...) at several workshops and conferences.
The topic of my thesis (diploma) was focused on a project of the DFG, a German Research Foundation, which was developed further in cooperation with other universities.
The result was ...[adjective or description]... due to my effective teamwork.
