I'm a Full Stack Software Developer based in Vienna, Austria, currently studying Software & Information Engineering at TU Vienna. My career has been shaped by demanding enterprise projects — from identity & access management systems for the Volkswagen Group to contract lifecycle platforms at Porsche Informatik — where reliability, clean architecture, and maintainability are non-negotiable.

As a freelancer, I bring that same rigour to your project, whether it's a greenfield application, a legacy modernization, or a missing backend service. I care deeply about code quality, documentation, and delivery — not just shipping features, but shipping them right.
