The service responsible for the full Bol shoporder data needed to be migrated from on-premise to Google Cloud Platform. This came with challenges due to the size of the data. We used insights into maintainability of the old system to design a more concise architecture while minimizing workarounds.

To improve maintainability and scalability of load to the multiple backends at Bol I helped design and build a federated GraphQL layer. Additionally I took initiative to protect backend services against DDoS attacks. I made a service in Golang to identify and block malicious bots.

The initiative KrampHub was started to migrate Kramp away from Websphere E-Commerce to a custom tailored microservice platform. I developed multiple microservices, and migrated users and functionality until we went fully live in 2019. I also wrote the backend to the Kramp App which included the api to the Kramp visual AI.

Referring a patient of an general practitioner to a medical specialist is done by using ZorgDomein for 90% of the cases. I worked at the team responsible for the Patient Portal, which is shown to a patient when viewing their referral. It is exciting to contribute to this essential service, however challenging because simplicity is very important when catering to user from very diverse backgrounds.
