Zalando – Procurement Portal
Lead Frontend Engineer, Coach
This greenfield project replaces Zalando’s existing procurement platform. After completion, the customer will use this portal to purchase fashion products for its shop for about 1 billion Euro per year, according to published numbers.
My responsibilities on this project involved technology selection, architecture, development and coaching of employees in the frontend technologies used.
DMG – Dentamile Connect
In this project the customer develops a SaaS for the digital, personalized production of dental products such as crowns and bite splints through browser-based CAD/CAM. A dental laboratory or dentist can digitally scan the patient’s jaw. Based on the jaw’s model, he specifies the desired product in a web browser in a CAD component in 3D, which uses WebGL. The individual steps are determined and sequenced by a workflow mechanism. Once finished, the user prints the design using a special dental 3D printer. The end product is directly usable by the patient.
My work involved mainly the design and negotiation of the API between the SaaS software and the WebGL CAD component built by another agency, as well as the API’s implementation. Besides that, I have setup the UI component library, implemented parts of it as well as various use cases.
