Why I build apps
I've spent my career simplifying complex systems and making technology feel natural. After years of designing products for others, I started noticing gaps — apps I wanted but couldn't find. So I decided to build them myself.
“I like things to work seamlessly in your everyday life. Why should it be difficult to use new technology? Everything can be made simple, or at least understandable if you just give it enough thought.”
MHJ Apps is my way of combining 15 years of UX expertise with hands-on development. Every app starts with a problem I experience personally, and I design and build each one from scratch — from concept to code to App Store.
“I'm an engineer by heart and my area of specialisation is the psychology of humans. I am more interested in what my user needs rather than what is technically possible.”
