Open source technology is at the core of Ultra Tendency’s history and business. Since 2001, our experts have made more than 6,000 source code contributions to more than 25 open-source software projects.
Celebrating Two Decades of Open Source Contributions
We believe in the unique innovative power of open-source projects, and this has been an essential part of Ultra Tendency’s DNA from the beginning. This long-standing commitment to open source makes Ultra Tendency unique in Central Europe.

Ultra Tendency encourages employees to contribute to open-source projects. Nine of our colleagues have the status of Apache community contributor and/or committer. For more than a decade, Ultra Tendency experts have been extending and improving these software projects when the General Availability version did not fully meet customer requirements. Ultra Tendency is also heavily involved in the Apache community, conducting meetups at company offices, regularly attending Spark Summits, and giving keynotes at major conferences.
On account of valued contributions, some of our teammates have been granted the privilege of independently modifying the source code of their respective projects. This guarantees unmated technological know-how as well as the fastest path to troubleshooting and the fulfillment of functional requirements.
Ultra Tendency employs contributors/committers for the following open-source projects: Scala, Kafka, Nifi, Ansible, Terraform, Terrascan, HBase, Hive, Ozone , Knox, Ranger, Oozie, Yarn, Checkov, Zookeeper, Sentry, Ambari, Bahir, Avro, Zeppelin, Yetus.
