Software Developer

11/2015 – offen

• Developed new features and improvements for the front-end report generation tool (.NET C#, WPF/WinForms).
• Analyzed and tested potential tools for scaling and stream processing (NoSQL databases like MongoDB, Cassandra and
messaging systems like Apache Kafka).
• Improved and extended software products to support new requirements and scalability using various languages and
technologies (Java, Python, Perl, .NET C#, Informatica ETL, Sybase, DB2, Hazelcast).
• Helped renovate an existing monolithic setup. New, asynchronous microservice architecture allowed us to utilize resources
and existing components more efficiently, in a cloud-friendly environment. The new, distributed infrastructure made use of
containerization (Treadmill), service registration/discovery (ZooKeeper), messaging (IBM MQ) and numerous proprietary
technologies providing services like Pub/Sub, etc. For orchestration purposes, we chose Cloudify.
• In accordance with DevOps principles, as a full-stack developers, we took responsibility for development, operation and
maintenance of the various applications.
