About Me

Markus Schall

Markus Schall – entrepreneur, developer, author. I write books that bring clarity: about TMD, databases, and dealing with personal crises.

My professional journey began with a traditional commercial apprenticeship. I then served in the German Air Force, where I quickly assumed responsibility and developed technical insight. Afterward, I worked as an IT administrator and soon specialized in database development—first as an employee, later as a freelance developer.

In the early 2000s, I ran my own Apple retail business. Since 2005, I have worked independently as a software developer, focusing on FileMaker-based ERP solutions. During this time, I supported numerous companies in building efficient digital processes.

In 2025, I began sharing my knowledge and experience as an author—starting with a medical book on TMD, followed by a database book and a personal work on crisis management. More books are in the works.
