My name is Pavol Vidlička. I am a developer interested in Big Data and distributed systems.

I am currently plying my trade at Barclays. I have helped to create and maintain data pipelines processing gazillion of impressions at My hands-on experience includes Spark, Hadoop, Hive and HBase with a healthy sprinkle of other general tools like Kubernetes, Grafana and Prometheus.

I studied Mathematics, which influences how I see computer science. Type systems, probability distributions, matrices or even self-adjoint operators do not scare me. In the past, I have done research on qualitative theory of piecewise-smooth ordinary differential equations. My Master’s thesis on the subject has been published in a peer-reviewed journal.
