Professional and project experience

  • 2015 until 2019: Senior Data Engineer, Avantgarde Labs GmbH, Dresden, Germany:
    • IT service provider with approx. 40 employees. My job included technical support for the ETL team of a large German e-commerce provider for electronic items; the ETL infrastructure consisted of 300 to 400 ETL jobs. On the one hand, I was responsible for creating, changing and optimizing ETL jobs using Talend Studio DI, and on the other hand for planning ETL processes and prioritizing tasks for a team of up to 5 employees. In the 5 years in the project three different Talend versions (5.3.1, 6.2.1, 7.0.1) were used. When upgrading the Talend Studio versions including the associated infrastructure components (Talend Administration Center, Nexus, git / SVN), I took over the technical coordination of the necessary steps in coordination with internal and external employees. A central database with a size of approximately 2 TB was used to combine the data from various source systems; until 2017 it was an Oracle database in version 11g R2, after that the database was migrated to PostgreSQL 9.6 and ETL infrastructure was transfered to the cloud (Google Cloud Platform using "Cloud SQL" for the database and VMs for the infrastructure components).

  • 2009 until 2014: Data Engineer, Tele-Kabel-Ingenieurgesellschaft mbH, Chemnitz, Germany:
    • IT service provider with approx. 80 employees. My task was the project coordination for and the implementation of approx. 80 geodata migrations for supply networks (waster water, electricity, gas) for a Swiss GIS provider, which performs the GIS tasks for about 50 Swiss municipalities. The migrations took place from Oracle database 9 to Oracle database 11g R2. In addition, I carried out various customization programming for Autodesk Topobase using VB.NET for the customer.
