Available for projects Senior Creative Developer — Hillegom, NL
25+ years of web development. A decade of realtime 3D. From Unreal Engine and AI-powered products to fullstack web — delivered with precision.
// 01 — About
RatchetWorks brings together over 25 years of web development and a decade of realtime 3D. I directed software development teams and led Unreal Engine projects. Now I bring that senior-level thinking directly to freelance projects — the strategic overview of a director and the hands-on output of a developer.
// 02 — What I do
I work across Unreal Engine, 3D pipelines and web/AI — so I can bridge gaps most specialists can't.
01 / UE5
Senior-level UE4/UE5 solutions with deep expertise in Lumen, Nanite and C++. I build plugins, custom tools and full experiences — including VR/AR for healthcare, training and architecture. I also take on consulting, mentoring and technical leadership roles.
02 / 3D
Custom Blender add-ons using Python and Geometry Nodes that simplify 3D workflows. GLB optimisation with texture baking and LODs. Seamless Unreal Engine integration — the kind of pipeline work that saves teams hours every week.
03 / WEB & AI
React apps, modern JavaScript and AI-driven automation. I build products end-to-end or slot into your team as a senior contributor. Strong on CI/CD, Git workflows, and making sure what ships actually works.

"I worked with Marco for nearly four years on building and evolving gall.nl. He's a highly capable, driven, and enthusiastic developer who speaks his mind. A pleasure to work with or have on your team. He picks up new things like A/B testing and React quickly and forms a clear opinion on them. Contributing to business value always comes first for him — pragmatic, independent, and completely trustworthy. Highly recommended!"
"I've worked with Marco as Project Manager on several occasions on the Nuon Newsroom, which we developed in WordPress. He was part of the concepting phase and the main developer in execution. At all stages he was a very reliable partner and delivered fast and great results."
