Microservice Data Tracing
As a tech lead, I built a system that traces data uploads throughout several microservices. This system can be used to provide real-time information on the current status of any data upload.
Bol.com is a platform where other businesses can sell their products. To do this, we offer them many channels to upload their product information. The handling of this product information works asynchronously and can take up to several hours. For many years, we provided no feedback whatsoever on these data uploads. Thanks to this tracing system users now get valuable feedback on what happened to their uploads.

Setup of the Front-end Microservice Architecture
I played a leading role in several iterations in which we pushed front-end applications into microservices. I set up a big part of the architecture that has been used by many front-end teams at Bol.com over the last three years.
