    Ioannis Dritsas

    iOS Developer, Quantitative Analyst, Games Developer, PhD

    United Kingdom - Tests: 3 - Portfolio: 4

    My goal is to put my quantitative analyses and software development skills to practise in serving your needs. My PhD work focused on the simulation based optimisation of non-linear systems in high dimensions. During those research years I realised that I have a talent in turning seemingly incomprehensible data into meaningful representations of underlying information. But I did not stop there. I developed novel algorithms that automate such processes to artificially construct optimal systems. Put simply, I develop iOS apps, solve quantitative problems, develop algorithms, optimise systems using mostly Objective-C, Matlab and C++. I also design and develop games using mostly, OpenGL ES, Open GL, Unity3D, C++, Photoshop, Blender. What fascinates me the most is developing today what is many years ahead compared to what is currently available on the market or embedding such qualities to contemporary products. To see what I mean, here is an advanced logic game with numbers that I have developed for the iOS platform: http://goo.gl/doJB0j  I would also like to highlight that during my years of work at Alcatel-Lucent as a senior design engineer I developed strong product development and time management skills to say the least. Thank you for your time and I am looking forward to putting my experience, skills, and education at your service.

    Andrew Swantek

    Ph.D

    United States - Tests: 2

    I have been conducting experimental research, both applied and fundamental, for 10 years in wide range of scientific problems. This has given me a mastery level knowledge of problem formulation, problem solving, and detailed analysis skills. My day-to-day coding/analysis is done in Python with packages such as: numpy, scipy, matplotlib, pandas, parallel python, scikit-image, scikit-learn, and h5py. I also have extensive experience with scientific/engineering software packages including: MATLAB, ImageJ, Photoshop, the and the R Language. My skill set also includes data analysis techniques for both sparse and large data sets. I have experience using spectral, correlation, statistical, and numerical analysis for problem solving with stochastic and multi-dimensional data. I regularly work with large time series data sets. Other interests involve data presentation and visualization, and machine learning for problems in engineering. My current work involves the investigation of automotive fuel sprays at Argonne National Laboratory.Typical data sets on the order of hundreds of Gb to 1 Tb. Our worked has garnished interest not only from the US Department of Energy, but also the automotive industry, whom we work with regularly.
