Hi there! I am a freelancer with a broad range of technical knowledge and interests. My areas of expertise include the design and implementation of graph-theoretical algorithms, linear and mixed-integer programming with google or-tools and cplex, solving differential equations for your physics/electrical engineering applications, writing fast and robust parallel c/c++ code, many body simulations and others. I can deliver high quality implementations on Matlab, Python and C/C++, where I have more than 10 years of programming experience, and on the less common language Delphi, with which I have around 1.5 years of experience. I am responsible and strive to complete all projects on time, without compromising the quality of the solution.

Erfaring

Freelance Python Developer (R&D)

Apr 2016 - Oct 2016 (6 months)

I was a member on a freelance basis of the research and development team of this young start-up company. I was responsible for the implementation of an algorithm for the optimization of the transport network of different logistics companies. The algorithm was implemented on Python 2.7 with the usage of state of the art libraries such as python pandas and Google or-tools.

Scientific Staff

Feb 2015

Currently I am employed as a scientific staff in the institute of nanoelectronics at the TU Munich. My employment is a part of a pursuit of a PhD degree in computational photonics, with main focus of research: the development of mathematically rigorous, physically correct and numerically efficient computational models for nano-scale optoelectronic devices.

Working Student

Sep 2014 - Jan 2015 (4 months)

At the institute I developed a heuristic algorithm for gain medium optimization of quantum cascade laser structures. As a result, wafers with two different optimized laser designs were grown and experimentally analyzed.

Working Student

May 2014 - Jan 2015 (8 months)

As a working student at the chair of Scientific Computing, I was responsible for the design, development and implementation of accurate, fast and efficient multi-dimensional integration techniques based on sparse grids on C++.

Working Student

Dec 2012 - May 2014 (1 year)

As a working student in Infineon, I participated in the development of a Windows application (on Delphi) for circuit analysis and netlist verification using data mining, image processing and graph optimization algorithms.

Junior Java Developer

Nov 2007 - Apr 2008 (5 months)

During my time at CPB I was a part of a 6-member team developing and maintaining a web-based mutual funds trading software. After undergoing special training to work with the company’s framework, I was engaged with the development and bug fixing of separate elements of the application.

Uddannelse

Bachelor of Science in Mathematics

2006 - 2011 (5 years)

Master of Science in Computational Science and Engineering

2012 - 2014 (2 years)

Bachelor of Economic Engineering

2009 - 2012 (3 years)
