Briefly about myself:
Bachelor: Mechatronics and Automation.
Master: Entrepreneurship and Business Design.
I’ve always been curiously pursuing opportunities to learn and gain new experiences and knowledge. In the recent years I developed several iOS apps and offered them in the app store; built my own CNC machine and 3d printers; got into CAD, photography, and web-development; co-founded Ophena where we developed and sold products for millions of Euros; designed logos and built websites for several not-for-profit organisations and for-profit companies; produced music; got into DJing on Weddings; co-founded a social venture operating in South Africa and Sweden; built eCommerce stores on Woocommerce and Shopify; developed microcontroller-driven QA-devices; fulfilment software using NextJS and Supabase – integrating Shopify with DHL for domestic and international shipments.
Some older projects below.

Who of Us Online
As my app store app will not be available any longer, I decided to develop an online version of the game. It is accessible here. The questions are stored in a mySQL database. A javascript then requests the questions via a php script. Nothing too hard, but I didn’t know how to do it… until I did it.

Windpferd-Reitsport
This project comprises the design of a logo and a website for a German retail store specialised in horse riding equipment.

Seven – 7
After I developed Who of Us and Zitate 2.0, I wanted to have a look at developing a game. At this time the game 2048 was a huge success. The game is fairly simple: You have 16 tiles on a 4×4 field and your goal is to push tiles into each other. The same numbers will morph (2+2=4; 4+4=8;…
