"Die Zusammenarbeit war fachlich wie auch im Team hervorragend. Sein technisches Know-how ist state of the art und war für das Projekt sehr wertvoll."
6/2022 – 9/2024
Tätigkeitsbeschreibung
Reengineering of the eHealthportal for digital identification cards in the context of the Gematik project. Keygoals are high-performance, off-loading performance from the Backend to the frontend, compliance with the WCAG 2.2 and optimized SEO for every page.
General
- For the customer facing portal the first task was to find the best architecture for the task. We decided for next.js, as it allows fine-tuned delivery of server or client react components, offers many caching strategies for frontend and backend, thus reducing load from the backend. We could also deliver static content, that was server-generated and deliver so a very fast customer experience while surfing the portal.
- For the administration frontend we used vite.js with react-admin. The journey was visually edited in the admin frontend with react-json-schemaform. The customer journey was developed as a lib, so the portal and the admin interface can use the lib to display the journey.
