John is an "all-round" technology designer and inventor with a Master of Science degree in Electro-technical Engineering and 25 years of experience in multiple areas: Data-Networking, Cyber Security, Software Development for Backend (Node.js), Frontend (React.js) and Apps (React-Native, Apple Swift/Swift-UI), including DevOps, CI/CD, Azure/AWS Cloud, Containers, Git version management, Test-Driven Development, design of Electronic-circuits/FPGA, Embedded Software (C/C++ for Microcontrollers, Sensors, IoT, BLE, WiFi, UWB, LoraWAN), and besides taking on freelance projects I work on my own inventions and products and I currently have 2 worldwide patents to my name.
I have traveled a lot for my work and besides developing and implementing technology, I have often worked as a technical consultant and frequently given presentations and technical training -- besides being good at technology, I am also good at human communication!
Privately in short: I am a single dad of 2 beautiful daughters who live with me half the week in Amersfoort.
