With this dirt bike, came my interest in mechanical engineering. This actually kickstarted my career as a car mechanic. Where I quickly worked my way up to become one of the few qualified Audi Sport technicians that is allowed to work on sports cars, such as the Audi R8!

Eventually I felt like I could learn even more and wanted to pursue my interest in electronics, so I decided to start studying next to my full-time job.

I started studying at HAN University of Applied Sciences Automotive Engineering in Arnhem.

During my studies I got recommended for a job as 'Electronical' Prototype Developer at Autodidact B.V., where I worked for more than 4.5 years.

I actually started my iOS journey way back in 2018, while I was still studying and working at Autodidact. Because Autodidact wanted to create an iOS app for the 'Automotive' Helpdesk EuroTech Center (which is a different department of Autodidact itself).

At the same time I was looking for a graduation assignment for my B.S. So we decided to combine the two and as a result I created the iOS app ETCA 'EuroTech Center App', which combines Automotive Engineering and iOS Development.

I actually recieved a 9 for this graduation project and graduated with honors 'Cum laude'! I immediately fell in love with native iOS Development in Swift.

When SwiftUI came out, I immediately started practicing with this new declarative user interface toolkit. Which resulted in my three latest created iOS apps Mi Shopping List, Cryptofy and eXandOs.

I actually enjoy every aspect of iOS development from designing to programming and always try to learn as much as possible along the way.

As a result of this growing passion, I decided to make a career switch and become a full-time iOS developer, currently at Flitsmeister B.V.

Interests & Hobbies

Next to my passion for native iOS Development I got a lot more interests. For example I got my own YouTube channel Hanni's Engineering, where I modify my car.

This way I can combine several hobbies of mine, such as customizing my car, videography and being creative in general. Not only with the customized modifications for my car, but also by designing and creating my own Merchandise for example.

Another big hobby of mine is Formula 1. Not only the racing but especially the technical aspect appeals to me. I love technology and absorbing as much new information as possible. From computer science, electronics and astronomy to automotive engineering.
