Jettro Coenradie

Technical Director

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.
