About

Hi, I'm Johannes — a Business Informatics student at DHBW Mannheim and corporate student at SAP, where I've worked across cloud engineering, ABAP extensibility, performance testing, and enterprise sales, including a rotation in Auckland, New Zealand.

I'm co-founding NEXtickets, a digital ticketing platform for small clubs and event organizers. I have a background in competitive robotics (RoboCup Junior — German Champion 2023) and still volunteer as an organizer and chair at qualification tournaments.
