Applied Mathematics

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.

Experience

Scientific Staff

TUM - Institute for Nanoelectronics
Feb 2015 - Present
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.

Freelance Python Developer (R&D)

Transmetrics
Apr 2016 - Oct 2016 (6 months, 1 day)
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.

Working Student

Walter Schottky Institute
Sep 2014 - Jan 2015 (4 months, 1 day)
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.
