Work, education and the projects that came out of them, from art school and tangible games through interaction design and research to the integration platforms behind retail, insurance and public-sector systems. Each project also has its own page.

May 2026-now
Work
Senior Integration & LLM Engineer
SPECTR B.V. · AlmereEmployed
API and integration work inside an enterprise AI landscape: MuleSoft services and REST contracts, Python components for document processing and prompt orchestration, and LLM and agent functionality joined to SharePoint and the other services a business already runs on, deployed on Azure Kubernetes Service. The consulting continues here: SPECTR is the employer behind the current engagement.
2026-now
Personal project
Home Energy Orchestration System
A household energy system rather than a gadget pile: Proxmox and Home Assistant running domain-based stacks for automation, monitoring, EV charging and surveillance, fed by a P1/DSMR smart meter, solar production, Zigbee devices and the EV charger. Dynamic tariffs are first-class: any flow that touches a load knows the current price. Built to the same rules as production systems: everything in Git with architecture decision records, observability from day one, local-first so the house still works when the connection does not, and boring technology on anything that heats or charges.
2026
Personal project
dvdm-i.nl rebuilt and relaunched
The site you are reading, put back up after some years offline. A static Astro build on Cloudflare, with the chronology as its spine: every project takes its date from the timeline entry that references it, so a year is stated in exactly one place. The portfolio itself had to be recovered, page by page, from PDF exports of the old site.
2026
Personal project
Personal automation on Windmill
No longer running
A self-hosted automation system on Windmill (Docker/WSL2, PostgreSQL), with scripts, flows and shared libraries kept in version control and synced to the workspace. It gathered and processed personal data, including Strava, Jefit and Garmin health records.

2. Project · 2018
  Memories Sharing
  A post box in a care home where residents write postcards about what they remember. The first version needed a person for every step after that. This one photographs each card as it drops, with a Raspberry Pi and a camera module, and sends it out to people who are not in the building, so that what they say can come back while it is still a conversation.

Apr 2009-Mar 2010
Work
(Web) development and interaction design consultant
Bikkels BV · AlkmaarFull-time
Taken on as a development consultant. With client placements not materialising, the work became interaction design on internal projects: gathering client and user needs and turning them into requirements, chiefly for the redevelopment of the company intranet. Acted as intermediary between technical staff and designers through brainstorm sessions, online requirements gathering and user studies, and compared CMS platforms and PHP frameworks.
1. Project · 2009-2010
  Intranet Bikkels
  A SharePoint intranet that everybody used and nobody could find anything in. Nothing was missing: it was a naming and structure problem, which the people who built it cannot see because they already know where everything is. So the redevelopment started with card sorting by the people who use it.
Oct 2006-Oct 2008
Education
PDEng, User-System Interaction
Eindhoven University of Technology
Post-master programme of the Stan Ackermans Instituut (3TU), to the degree of Professional Doctorate in Engineering. International, multidisciplinary teams across user experience, interaction technology, user needs and evaluation methodology.

  Usability expert and researcher on the Simplicity Labs project: a quantitative comparison between traditional laboratory and online experimenting.
  1. Project · 2008
    Philips WebLabs
    A web platform for gathering user feedback at any point in a design cycle, and the question behind it: whether people tested at home, on their own machines, behave as they do in the usability lab. Philips wanted that measured, not asserted.
2003-2007
Work
Freelance creative designer
DvdM-interactiveFull-time
Small and complex websites, CMSs with user levels, and client-specific applications built from scratch: Cretus.com, Errél.com, Illume Candles, NJoy live.nl. The JVH brands among those were built freelance while also working there, hence the overlap.

2. Project · 2004

Project
Roots.nl
A webshop, built when buying online was still an argument rather than a habit.
Sep 1998-Feb 1999
