My interests

I am tackling challenging and impactful data challenges in industry and research. I blog about the local data stack and data related topics and organize local data meetups.

Sometimes, it looks crazy - but it is just complex!

Scaling data pipelines @Magenta Telekom

Magenta Telekom ingests many terabytes of new data every day, and every downstream consumer wants it immediately. The real bottleneck turned out not to be hardware but humans wrestling with hidden, hard-wired dependencies in hundreds of heterogeneous pipelines and sometimes tool silos.

Scaling data pipelines @Telekom

Join the Vienna Data Engineering Meetup on the 9th of April. Scaling data pipelines @Telekom Aleks and Georg share how Magenta Telekom is handling their data challenges by turning data dependencies, tooling silos and development from being a problem into a helpful component of Magenta`s data platform. They start by covering the basic principles underpinning the data platform, discuss the current challenges in the domain of data engineering and share how these are solved for Magenta. They finish by sharing how building around the orchestrator - makes it easy to build for scale.

Pixi

Pixi powering Telekom data cloud

Pixi is a tool which enables efficient dependency handling. It is created from prefix.dev, built in Rust and very fast. For us at Magenta Telekom in Austria Pixi is beneficial as we build our new data platform around metadata and strong governance and an explicit graph of data dependencies. In this talk we share our experience with Pixi and how it empowers our data infrastructure - in conjunction with Dagster.

Python

Cost efficient alternative to databricks lock-in

Spark-based data PaaS solutions are convenient. But they come with their own set of challenges such as a high vendor lock-in and obscured costs. We show how to use a dedicated orchestrator ([dagster-pipes](https://docs.dagster.io/guides/dagster-pipes)). It can not only make Databricks an implementation detail but also save cost. Also, it improves developer productivity. It allows you to take back control.
