Marcel Walder

DevOps Engineer (Working Student) at NXP Semiconductors Austria · B.Sc. Software Engineering & Management at TU Graz

I work on AWS infrastructure as code, CI/CD automation, Linux servers, and streaming data observability. Alongside my work at NXP Semiconductors Austria, I study Software Engineering & Management at TU Graz and adapted CyberRangeCZ Lite with custom patches and OT training scenarios for my Bachelor's thesis.
