Tobias Schulze-Heinrichs

I work as a Data Scientist with a track record of managing end-to-end data science projects. My work includes the full spectrum of data science tasks, including research, EDA, feature engineering, deployment of machine learning models into production and evaluation of A/B tests. Projects: * Predicting career level and work-experience of job postings (NLP, Classification Problem, Data Augmentation) * Predicting salary expectation for job postings (Quantile Regression, Interpretable Machine Learning)

As a Senior Data Engineer, I played an important role in designing, implementing and operating robust data pipelines using state of the art technologies such as Apache Flink for stream-processing, Spark and Hive for batch processing and oozie/airflow for orchestration. I worked closely together with other jobroles like data-scientists, designers and backend engineers in a cross-functional team. Besides all that I was training interns, apprentices and juniors and helped them to grow.

I was responsible for designing, implementing and operating a retargeting system. That includes on the one hand high performant microservices for tracking, realtime bidding and recommendations. On the other hand I was responsible for the providing those big amounts of data to the data-science team and enabling them to build machine learning models. Projects: * Building and operating an End-to-End Tracking and Profiling System to handle large amounts of incoming requests * Building and operating a RTB system
