After studying tax law between 2008 and 2011 at the University of Applied Sciences for Finance in Königs Wusterhausen, he completed - in addition to his work as a tax official of the State of Berlin in the area of non-profit law - the study of law with a focus on corporate and tax law at the University of Potsdam, which he completed in 2016 with the first state examination. During his subsequent legal clerkship at the Berlin Court of Appeal, he deepened his relevant knowledge with specialized stations, inter alia, in the Department for Non-Profit Law at the Federal Ministry of Finance, in the tax law department of an international business law firm as well as at the 8th Senate of the Berlin-Brandenburg Fiscal Court - which is responsible for matters relating to nonprofit law.
Since being admitted to the bar in fall 2019, he has been working for SCHOMERUS – initially in Berlin, from 2020 to 2025 in Munich, and now back at the Berlin office.
In spring 2022, he completed the part-time master's program "Compliance" at the University of Regensburg. His master's thesis entitled "The Appropriateness of Executive Compensation as a Compliance Risk in Non-Profit Organizations" was graded "very good" (1.0).
