Testdeployment of a big data infrastructure (Hortonworks, Ambari, Docker, Vagrant, Bash). Final planning and provisioning of the cluster (rights management, security and access, directory services connectivity (AD/LDAP/Kerberos), terminal server, secure integration of software components and repositories. Training and consulting of data scientists for scalability of single/shared memory algorithms towards big data (Spark, Hive, Hadoop) and utilization of continuos integration (Jenkins, Git).

* Projects in the field of R&D or engineering (e.g. signal processing, integral transformations, theoretical focus with algorithms, modelling, analysis, statistics, numerics, computational physics) are very welcome if the project has some overlap with my main focus of software development and big data.
* I have many years of experience as Linux-User (since 2003 exclusively Linux at home) and administrator (since 2009).
* I've specialized knowledge about search engine optimization, ecommerce and the development of corresponding client-tools.
* I can provide my list of scientific publications on request.
