Summary
👤
Senior🎓
Top SchoolChristian Mark is an Application Security Engineer with 9 years of hands-on experience in embedded hardware-software development, IoT security, and distributed systems, recently completing an MSc in Computer Science with a cybersecurity specialization at DTU. He has driven security integration and vulnerability management across development teams, introduced SAST tooling, and led IEC62443 and ETSI EN 303 645–oriented efforts for IoT products while working on Yocto‑based firmware in C. Comfortable across the stack, he pairs embedded Linux and firmware expertise with cloud DevOps (JS, Python, Go) and practical threat modeling using STRIDE. Having built production test automation, logging/monitoring services, and a FIDO-based 2FA Android prototype, he thrives in R&D settings at small-to-medium hardware-software companies focused on security. Colleagues know him as detail-oriented and pragmatic—someone who blends disciplined military-style planning from his Royal Guard experience with a hacker’s curiosity (aptly summarized on GitHub as "Catching Predators and writing code").
