• Creation of an internal accessibility guide

Oskar Oldorf (project lead): "I had the pleasure of working with Patricia for over a year on a project focused on ensuring digital accessibility for the online presence of a company in the financial services sector. During that time, I got to know her as a dedicated, detail-oriented, and highly skilled colleague.

Patricia was responsible for independently conducting gap analyses and worked directly and efficiently with key stakeholders. Her role centered on assessing compliance with the BFSG and providing strategic guidance to editorial teams on creating accessible content.

What I particularly appreciated about Patricia was her ability to think beyond the status quo and bring fresh perspectives to the table. She combines strong subject matter expertise with a keen eye for detail and a structured, thorough approach. Her input often sparked valuable discussions and helped us move our work forward in meaningful ways.

I can wholeheartedly recommend Patricia—especially for roles where precision, strategic thinking, and a high standard of quality are essential."
