Electronics & sensors
Circuits on ESP32, Arduino and Raspberry Pi, PCB design and sensor networks that collect data from the real world.

Product Engineer
Systems, automations and products from idea to full delivery. Planning, software, electronics, 3D printing and AI under one roof.
01 · Process
From idea to a working product.

Plan
I break the idea down: what it does, what it is made of, what it costs and what to test first.
- Feature map
- Cost estimate
- Test plan
- 02 / 04
Prototype
A first working version: board, code and printed enclosure, so you can test the idea in your hands.
- Working circuit
- First firmware
- 3D print
- 03 / 04
Build
I refine the electronics, software and automations. You see progress at every stage.
- Device
- App
- Automations

Launch
Go-live, a short batch or production run, documentation and support after launch.

02 · Services
The whole product. One person.
You don't need to assemble a team of five specialists. I design the electronics, write the software, print the enclosures and tie it all together with automation and AI into one working system.
Software & apps
Web and mobile apps, control panels for your devices and backends that take in data from thousands of readings.
Automation & integrations
Processes that run themselves: MQTT, Home Assistant, n8n and webhooks connect devices, apps and people.
Prototype & production
From the first unit to a short batch: ordering boards, assembly, testing and getting it ready to ship.
3D printing & CAD
Enclosures, mounts and mechanical parts designed around the electronics and printed in hours, not weeks.
Artificial intelligence
AI agents, search across your own documents and computer vision, running on the device or in the cloud.
