When I was approached in 2014 to start a new Luminis business unit together with Sander Pagie, I seized this opportunity with both hands. What a journey that has become. Together with Sander I set up the business, shaped the team and helped many customers. I think it is important to work together with a multi-disciplinary team on strategic solutions for (search) related challenges for clients.
I am an experienced software architect with a focus on search technology. For years I have been working on the best search solutions for clients based on tools such as Elasticsearch and Solr. In addition to designing the architecture of search solutions, I still enjoy programming myself. Develop your own APIs based on, for example, a spring boot, build your own interfaces with React and think for yourself about the best way to make all that beauty available to users. This is possible via cloud-based solutions, but also on dedicated hardware.
In addition to providing search solutions, I also enjoy talking to others about this. I have already helped many teams with an elastic search training. I also spoke about search-related topics at several conferences.

Deploying a secure AWS Elasticsearch cluster using cdk
If there is one thing that I have seen a lot with elasticsearch clusters in the wild, it is problems with security. The out of the box Elasticsearch installation does not have a user_id password protection like most databases do....
Let’s talk about the Elastic license change
Is it a bomb under the open source model, or a genius move to protect their business from pirates? On January 14, 2021 a blog post was published on Elastic’s website, titled: licensing change. In this blog post, they announced...
Building resilient connections using a circuit breaker
Software systems are more and more integrated systems. They integrate with datastores, with log and monitoring systems, with services provided by other components (micro-services) and with SAAS from external parties. When using the cloud to run software components, they need...
