David Van Mosselbeen is a versatile freelance IT professional and security analyst based in Brussels with over two decades in computing and eight years of focused freelance experience. He blends offensive and defensive security (vulnerability scanning, penetration testing, integrity checking, audits) with hands-on systems engineering across Windows and Debian/Linux, cloud, VPN and web server stacks. Equally comfortable in web and UI/UX design and full‑stack development (Python, PHP, JavaScript, CMS platforms) he also applies a maker’s curiosity to flight-simulation development and custom tooling like his earlier GUICMS and PyGUICMS projects. A trained IBM Cybersecurity Analyst and certified UX practitioner, he pairs technical depth with creative skills in photography and 3D/GFX—an unusual combination that informs pragmatic, human-centered security and product design.
