I develop technology products and the business around them. I look at technology through customer needs, product capabilities and market realities. Here, I share my perspective, try out new tools and write about what I learn.
Technology must not only work, but also reach the market.
Most of my experience comes from building automation, IoT and the electrical engineering industry. Working with engineers, installers, distributors and customers has taught me to see the same product from different perspectives. I’m interested in how technical capabilities translate into a useful solution, a clear product offering and business growth.
That curiosity also leads me to AI and projects of my own. I test tools in practice and write about my observations. What interests me most is what remains useful once the initial excitement around a new technology fades.
