👋 Hey, I'm Bart

Security practitioner focused on building and breaking things the right way.

I operate at the intersection of information security, infrastructure, and developer tooling. My work is driven by a pragmatic approach: understanding how systems actually behave in practice, identifying where risks emerge, and implementing solutions that are both effective and responsible.

This GitHub reflects that mindset. Most of what you’ll find here is not theoretical, but built from real-world use cases, testing, and iteration. I focus on creating solutions that are reproducible, maintainable, and applicable beyond a lab environment.

I’m particularly interested in:

  • Continuous security testing and exposure management
  • Secure-by-design infrastructure (from homelab to production)
  • Simplifying complex networking using tools like Tailscale
  • Bridging the gap between security, operations, and development

My background includes working with both technical and organizational aspects of IT environments, including governance and compliance. I value structure, clear documentation, and communication that works for both technical and non-technical stakeholders. Reliability, discretion, and quality are central to how I approach my work.

On this profile, you’ll find a mix of:

  • 🔐 Security research, notes, and practical findings
  • 🐳 Docker / Compose patterns and infrastructure setups
  • 🌐 Tailscale-based networking and sidecar designs
  • ⚙️ Automation and real-world configurations

Everything here is something I’ve built, tested, or analyzed myself.

I have a strong focus on continuous improvement. I actively develop my expertise, share knowledge where it adds value, and take ownership of outcomes. The goal is simple: build solutions that are not only technically sound, but also usable, scalable, and aligned with real-world constraints.
