I am a Full-Stack Software Engineer and Master’s student in Informatik at the University of Passau, specializing in high-reliability system integrations, custom middleware, and AI-driven platforms. With over four years of professional experience across the MERN stack, TypeScript, and Python, I excel at turning complex business logic into scalable, automated infrastructure. My engineering approach centers on extreme ownership—whether I am architecting an enterprise portal handling thousands of active users, re-engineering queuing systems to solve critical data synchronization race conditions, or developing internationally recognized mHealth and AI/VR training applications. I thrive in agile, "builder-first" environments where technical excellence, data integrity, and cross-functional collaboration are the standard.
