Discover Tempus →I’m Michel Storms, an independent Apple-platform developer based in Belgium. My background spans architecture, manufacturing, machining, and programming—fields that taught me to think in systems and sweat the details.
I design and build native software across the Apple ecosystem, always aiming for the same thing: a clear idea, thoughtfully executed.
The same product thinking, engineering care, and attention to detail behind my apps—described by people I have shipped software with.
Michael stands out as the most exceptional Apple developer I've encountered. Throughout our year-long collaboration, he has consistently met and exceeded the project goals. His innovative approach brought fresh ideas that significantly enhanced our project's scope and potential. His attention to detail, love for the project and commitment to quality are extraordinary.
Competent and capable mac developer with solid software engineering skills. Takes ownership, including challenges, makes useful suggestions where there are options, and proceeds to take the project to a successful completion. Professional, Talented, and A-List. Recommended without reservation.
Michael was incredible to work with and some of the best macOS code that I have seen. His quality is impeccable and he is so incredibly systematic. I would hire him for another project in a heartbeat.
Michel did a great job, excellent communication & documentation of his work. He solved problems fast & good, even in difficult situations he had every time a proposal how to solve. I'm looking forward to our next project.
Michel was a fantastic asset to the project and I will work with him again anytime. The Best of the Best!! Highly recommended!
Very patient and good communication. Helped me walk through and troubleshoot the problem.
Alongside my own apps, I take on selected contract work where deep Apple-platform experience and product thinking can make a meaningful difference.
