    John Volock

    Computer Scientist and Mathematician

    United States - Tests: 2

    In 2012, I finished dual bachelor of science degrees in Applied Mathematics and Computer Science. I've spent the past few years doing data analysis and data science on about any subject you can think of in my spare time, along with progressing towards becoming an actuary. In my day to day jobs, I've done everything from building custom website components to integrate services or other items, to building custom coded desktop or matlab applications to process data. My core competencies lie in anything involving data analysis/formatting/science. I'm extremely proficient at Java, Matlab, R, Smalltalk. and any scripting language. I prefer a challenge and to push myself to give the best possible end product, not just a feasible solution.

    Harsh T.

    Research Asistant (Physics, Materials Science)

    Germany - Tests: 2 - Portfolio: 2

    Being associated with Physics and Materials Engineering since last 7 years I have cultivated immense visualization and analysis skills neccesary to crack complex problems in Science. I not just have a know-how of various physical and mathematical theories but also a spin off incubated grip over multivariate statistical data analysis. Since last few years, my association with scanning probe and optical imaging techniques has allowed me develop a powerfull grip over image processing and adhoc solutions for data analysis, curation transformation etc in MATLAB. Given my background I can: 1. Find solution to almost any kind of day-to-day problems encounterd in professional world. 2. Help make sense out of experimental data using multivariate analysis, or suggest solutions for better setting up of the experiemnts in order to get the right information. Can model day today experimenal problems using multiphysics platform, COMSOL; e.g. modelling of a sample holder to know how efficiently it can work etc. 3. Data curation, transformation and novel visualization.

    Vasileios Fragkas

    Data Scientist & Java Developer

    Greece - Tests: 3

    I am well-versed in Software development, with knowledge and experience in Java. I have programmed various applications, and I am capable in Object Oriented Programming. I also have SQL and Database Design knowledge, having created databases in the past. Since July 2014 I have also been studying Data Science through Coursera, edX and other platforms, and I can use R to manipulate datasets, derive conclusions and prepare machine learning algorithms. I can use various preparation (data cleaning, data selection, charts, etc), pre-processing (centering, scaling, PCA, Imputation, etc) and modeling (Inference tests, Regression, ANOVA, Classification, Random Forests, Boosting, Bootstrapping, etc) methodologies. I also know Excel (data manipulation, charts, Pivot tables, Lookup, Optimization) and VBA. Currently I am learning Android. I have a wide range of knowledge in many fields (although I am not specialized in any of them), which allows me to utilize data more effectively than someone who has no idea how the data are related and simply tries to combine them randomly. My interests include (but are not limited to) Astronomy, Meteorology, First Aid/Medicine, Information Technology, Economics, Psychology, Artificial Intelligence and Computer Graphics. Finally, I can work both in teams of any size, as well as alone, and carry out my tasks responsibly and in time. I am used to handling deadlines, and I have worked with many teams in various settings (corporate, army, university, etc). You can find more about me in the following sites: https://gr.linkedin.com/pub/vasileios-fragkas/9b/8b5/7b6 https://github.com/Twilight-Hacker https://plus.google.com/u/0/115934857925554627693/about A personal blog is also being prepared and will be added soon.

    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.
