About Henk
I design and build technical products, with a focus on AI, machine learning (especially on image data), and data-driven systems. Using my experinece, I can help companies to create a proof of concept from ideas or productize and mature a proof of concept into a real product.
My background combines software engineering, applied machine learning, and product development. I work end-to-end: from idea and architecture to mature implementation and validation. Typical work includes computer vision, training pipelines, validating, modeling, and integrating ML into real-world systems.
What I bring:
- Strong analytical and system-level thinking
- Experience with Vision ML / AI applications in practical environments
- Ability to move from concept to working solution quickly
- Pragmatic approach: build what works, iterate, improve and mature
- Hands on problem solver

- TomTom Product Lab,System Architect/Principal EngineerAUTOMOBILEJanuary 2007 - January 2017 (10 years)Eindhoven, NetherlandsThe Product Lab is responsible for the development of new concepts and products. Prototyping is used toshow technical feasibility, usability and business value..Examples of responsibilities and achievements:+ Development of a number of computer vision and autonomous driving related prototypes and demonstrators.Mining of map data and lane level positioning was demonstrated using low cost sensors and a camera.+ Development (with 10-15 architects and engineers) of a research platform used to prototype new concepts. Manyof the concepts and ideas are now used in TomTom's navigation engine.+ A motorcycle-specific route planner was considered infeasible within the technical and time constraints. Idemonstrated that a simpler approach could overcome these challenges and successfully implemented the feature.+ Development of robust Kalman filters for positioning using various sensors.
- VDO Car Communication/SiemensVDOSoftware Engineer/ArchitectJanuary 1998 - January 2007 (9 years)Eindhoven, Netherlands+ Develop and improve algorithms for vehicle localization running on devices with limited resources. Often incollaboration with other development sites (Germany, France, China) and car manufacturers.+ Define and develop new architectures for the positioning component in new navigation systems.+ Support sourcing and validation of sensors.
