Open to freelance and smart-home work

Selected projects

Infrastructure, automation and the software that ties them together. Each entry names what was built, what it runs on, and what changed as a result.

Smart home automation at pyxels

Co-founded a studio that designs and installs complete smart-home systems: lighting, climate and security, running on a network built to carry them. Every install starts with the infrastructure, because automation is only as reliable as the link underneath it.

  • Home Assistant
  • Wi-Fi 7
  • 10GbE
  • Zigbee
  • ESPHome

Multi-room installations delivered end to end, from cabling to dashboard

Applied research2025

Hyper-local weather forecasting for heat pumps

A forecasting system that corrects national KNMI predictions against locally placed sensors, so a heat pump can be scheduled against the temperature at the house rather than at the nearest weather station. The model was trained on records going back to 1950.

  • Python
  • TensorFlow
  • KNMI API
  • Home Assistant

Hourly forecasts up to 48 hours ahead, computed entirely offline
