I work as a Data Engineer at Plista. On a daily basis, I work with Scala, Akka, Kafka, Docker, Cassandra, RabbitMQ, Mesos, Parquet and Bash.
In the last years, I was involved in different projects in Berlin. A few them are: Zalando, RebateNetworks and Hipaway. I worked for Discavo, a startup in the hotel business based on play! microservices.
When it comes to performance and scalability, I am used to developy on AWS, Bare-Metal datacenters and Mesos as a cluster resource manager.
During my studies at the TFH Berlin (Bachelor) and the HTW Berlin (Master), I got the change to dive into all kinds of different topics and challenges.
- My talk on the Codemotion 2016 conference was about Reactive Streaming with kafka and akka
- My master thesis was about distributed and Cluster-based Dimensionality Reduction. I compared different algorithms to reduce the size of matrices and implemented Random Projection base on spark, 2015, HTW-Berlin, Prof. Dr. Debora Weber-Wulff
- During my master studies, we created music recommendation engine based on audio features. We created train-sets of 10 different categories, defined ~100 different feature combinations (like MFCC, zero crossings or spectral rolloff) and trained and compared different algorithms for predicting the category. Furthermore, we created a recommender to suggest similar audio tracks based on different similarity measurements

Within another work during my master studies I wrote about realtime monitoring for distributed web-applications.

As a part of my master studies, I wrote about my three-month volunteering in north India (himalaya) where I teached tibetan refugees in different, computer-related topics.

In my bachelor thesis I was dealing with Model Driven Development (MDD) and implemented an application for creating surveys based on MDA, a standard definde by the OMG.
