Tätigkeitsbeschreibung
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.
Goals:
- Establish best practices
- Feature development
Highlights:
- Built relationships with partner companies
- Designed and negotiated the API between the SaaS software and the
WebGL CAD component built by another agency, as well as the API’s implementation.
- Setup of the UI component library
- Coached other frontend developers
