After more than 5 years we have to say goodbye. Since his internship in the summer semester of 2017, Rainer Meindl has been working as a research assistant in the AIST research group. He has been involved in countless projects such as Drive for Knowledge, AKFA, VOIGAS and TrueSize and has mainly worked on topics in the area of software and microservice architecture, but also on data quality. Especially with the latter topic he will continue to work at the Software Competence Center Hagenberg or in the course of his dissertation. We look back on some wonderful years with Rainer as a research assistant and system administrator of the research group, but above all look forward to a future with a won friend whose path has accompanied us.
