About

I'm a Distinguished Consulting Engineer at MongoDB, where I set the cloud and security governance that our Professional Services organisation runs on. Since November 2024 that work has halved the department's cloud spend and taken it from 66 critical severity findings to zero on unchanged infrastructure, with highs down from 229 to 10.

I hold OSCE3, OSCP and OSDA — so I know how the controls I write fail under attack. Twenty years building systems, more recently spent breaking them. I have been the primary AWS administrator on every estate I have run since 2013, and I hold an MBA, which mostly means I can explain to the people who control budgets why a finding matters.

Based in the Netherlands.

What I work on

  • Cloud and AWS security governance at organisation scale
  • Web app & exploit development (OSWE / OSED-level)
  • Cloud & AWS exploitation, IAM chaining
  • DevOps-aware attack simulation (CI/CD, containers)
  • Red team tooling & lab environment design

What I'm building

Project
w1ld0s Idempotent bash provisioning for a reproducible Ubuntu 26.04 pentest workstation — per-tool venvs, manifest lock files, no Kali coupling.
w1ld0s-tools Operator command layer on top of w1ld0s — recon, access, infra and AD workflows, engagement state, and offline cheatsheets.
exploit-tools Exploit development tooling, focused on Return Oriented Programming.
exploit-development-scripts Scripts used when reverse engineering and doing exploit development.
payloader Payload generation from a simple CLI, for faster access to custom payloads.
