Hej, I'm Thomas. I architect & engineer unique interfaces & interactions for the browser platform.
I've shipped software for 12+ years now: E-commerce platforms in the aviation industry. Educational installations on site. Internal logistics systems that cannot fail. Since 2022 as a Senior Software Engineer at SprintEins, where I spend my days finding the right rhythm between structure and feel.

An on-device UI for parcel lockers, located throughout Germany. The lockers are open to multiple providers, which means that various international logistics companies and their systems are integrated. With the UI displayed on the internal screen, customers and couriers can handle automated pickup and drop-off across first- and last-mile delivery. The webapp is designed to run on a variety of hardware platforms of different manufacturers and connecting and processing their sensor data.
