About

Hi, I'm Robert. My passion is to design and build software. I have a wide range of experience with software development in both backend as frontend technologies. Several of my personal projects can be found on my GitHub profile.

Experience

Backend Developer

at Bol. 2023-jan - 2024-apr

Kotlin, Golang

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.

Backend Developer

at Bol. 2022-march - 2022-december

Kotlin, Golang, GraphQL

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.

Backend Developer

at Kramphub 2019-januari - 2022-march

Kotlin, Golang, GraphQL

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.

Fullstack Developer

at Zorgdomein 2018-june - 2018-december

Scala, Angular

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.
