IoT & Hardware
ESP32 IoT and hardware that actually works in the real world.
From smart locks to plant-watering systems, I design and build IoT solutions end to end — firmware, hardware and the app that controls it. I'm an ESP32 specialist with hands-on soldering and real product-development experience.
If it needs a sensor, a microcontroller and a cloud connection, I can take it from breadboard to finished product.

Can you build custom IoT and hardware solutions?
Yes. Kaspar is an ESP32 specialist with hands-on soldering and product-development experience. He builds smart locks, automated plant watering, smart booking and heating systems, connected vending machines, and other bespoke IoT devices using ESP32, C++, Arduino, and Raspberry Pi.
How much does it cost and how do we start?
The first 2 hours of work are free, and the initial consultation is a no-obligation 15–30 minute call. You get world-class development at Estonian rates rather than London prices — for example, self-hosting the open-source Kanban tool can be set up for around £80 plus roughly £3/month in server costs.
