My Projects


Data Scientists spend a significant amount of time on building features which are certain characteristics or patterns in the inspected data. This is especially true for timely annotated data such as time series and sequences. Now, the python package tsfresh frees your time spend on building features by extracting them automatically from time series.

About Me

Maximilian Christ

I am a passionate Mathematician who pursues a Ph.D. besides his business work. As a Data Scientist, my interests and experiences in Programming, Classical Statistics, Distributed Systems and Machine Learning help me to realize measurable business value.

My Career

Diverse Clients

As a Freelance Data Scientist / Data Engineer I have consulted clients from the Internet of Things (IoT) and Finance environments. I focused on developing systems that solved dynamic problems, which involved the analysis of time series with help of statistics and machine learning. In finished projects I have implemented an automated annotating of sensory time series or developed a classifier for an intraday trading strategy.

October 2017
Freelance Data Science Consultant

Blue Yonder

Consulting clients about Predictive Applications in the industrial sector. Finished projects investigated the statistical and technical feasibility of data driven decisions for Industrial Applications. Such can be used for predictive maintenance as well as for the optimization of discrete and continuous production of simple (e.g. steel billets) and complex goods (e.g. electronic control units). Further participating in the BMBF and BMWi funded research projects "iPRODICT" and "Sepia.Pro".
