Willem van Heemstra: Cloud & Security Engineer

DevSecOps expertise that keeps your infrastructure secure and your deployments smooth.

Delivered by a multi-lingual engineer with 25+ years of hands-on experience and security analysis training.

I get it…

  • Your cloud infrastructure is a tangled mess, and you're worried about security gaps.
  • Deployments take forever, and your CI/CD pipeline keeps breaking.
  • You need Infrastructure as Code, but don't know where to start.
  • Security vulnerabilities keep popping up, and you're not sure how exposed you really are.

Sound familiar? You're in the right place!

“Willem optimized our entire DevOps pipeline and cut our deployment time by 60%. His security audits caught vulnerabilities we didn't even know existed.”

Hi, I'm Willem

After 25+ years of building secure cloud infrastructure for companies like ASML, Philips, and CGI, I know exactly how to bring order to your DevSecOps chaos without the corporate overhead.

As your Cloud & Security Engineer, I'll:

  • • Harden your infrastructure and patch your vulnerabilities
  • • Automate your CI/CD pipeline so deployments just work
  • • Build Infrastructure as Code that scales with your team
  • • Provide security posture overviews you can actually understand

I'm practical, detail-oriented, and fluent in English, Dutch, German (plus French and Spanish). Whether you need someone to architect your Azure environment or hunt down that security risk, just give me a shout!

And yes, I can explain Terraform to your CEO in terms they'll actually get 😉
