SKILLS
Education

since 2019 Doctor of Business Administration (DBA)
FHDW (Fachhochschule der Wirtschaft) Paderborn
in cooperation with Edinburgh Business School (Heriot-Watt University)
To deepen my research about „Machine Learning for Finance“ in the context of my own trading platform and to publish my findings about it, I am going to work on a doctoral dissertation about that topic over the next few years.


2010 till 2013 Master of Science in IT-Management and Information Systems
FHDW (Fachhochschule der Wirtschaft) Paderborn
To achieve my goal of a master’s degree, I continued studying at the FHDW. This time with an emphasis on IT in the context of economical challenges of today’s companies. At the same time a focus was put on fostering and improving the leadership qualifications of the students. During these studies I attended an optional excursion to China.


2008 till 2010 Bachelor of Science in Applied Information Technology
FHDW (Fachhochschule der Wirtschaft) Paderborn
Because of my educational background at the b.i.b. it was possible for me to acquire the bachelor’s degree in just 18 instead of the regular 36 months. Besides deepening the IT skills, there was put an emphasis on improving the soft skills of the students.


2005 till 2008 Advanced Technical Certificate & IT-Assistant Qualification
b.i.b. International College Paderborn
Focus areas were software engineering and development, databases, electrical and process engineering, operating systems, networks, multimedia and web.

PROJECT HISTORY
  • 10/2009 - Present

    • Private
  • Business Analyst, Software Developer & Architect
  • Project: Software Product Line (SPL) Platform, Value Investing, Automated Trading

    Industry: Finance, Exchanges, Trading, Forex, Stocks

    Based on my own developed software product line platform (similar to Spring-Boot but developer much earlier), a trading platform is being developed that makes it possible to generate trading strategies automatically. To parallelize the calculations, a backtesting system was created to facilitate cloud scale computation. The strategies also support live-trading which I am doing profitable for a few years now. This work builds on my private research and functions as a long-term project on top of which currently multiple commercial products are being created in cooperation with internationally distributed individuals and companies. I am also writing my doctoral dissertation about this over the next few years.

    With the development platform beneath it, other products and websites were developed. A new type of Naked-Objects-Framework based on Wicket was also created for this to reduce the development time of form websites drastically. Also a high performance No-SQL-Database for timeseries processing. Performance optimizations happen at a level of high-frequency-trading. Large parts of this development platform (not the trading platform) have been made available as Open Source here: http://invesdwin.de/

    I work on these projects besides working full-time as a freelancer (how much depending on the projects).
