Niek - A young man with brown, messy hair, light facial hair, and a slight smile.

Hello, it’s Niek

I am a senior AI & Machine Learning Engineer who designs, builds and deploys production-ready ML systems. From the model to the backend to ML Ops.

5+ years.

Zero demos.

All production.

I build AI systems that are meant to run in the real world and not just impress in a notebook. From model design to backend integration to MLOps, I own the full lifecycle so you don't have to stitch together three different specialists.
