    I have 10 years of experience in different areas of software development. My most recent experience lies in field of backend development of horizontally scalable solutions for data processing. During last 2 years I have been developing from scratch proprietary framework similar to Apache Hadoop and Spotify Luigi for batch data processing (billions of log records of ad data daily). I used Python as core language to promptly prototype data analytics business logic with a goal to rewrite it in native language without API changes later. This project also involved managing NoSQL databases (TokuMX or MongoDB 3+ with an appropriate storage engine) to process, aggregate and store massive (hundreds of millions daily) number of documents, indexed for further statistical analysis and reports generation. I also have experience in the following areas: - development of web backends in Python using uWSGI and Tornado frameworks - automation of code building and deployment, Vagrant, Docker - C# language and some experience in Java and C/C++ I am an open-minded technology enthusiast with strong algorithmic and mathematical background and keen attention to details. New language, technology or framework required for next project is not a problem to learn at all. I am ready to show positive, constructive and helpful attitude to your tasks.  less

    I started as a physics teacher after my graduation from university but I always had in mind to become a scientist and if possible to combine that with teaching. Also, as I like biology it was always my goal as a scientist to apply physics to the study of biology. During my MSc and PhD research projects, both on plant physiology, I extented further my knowledge on plant sciences, namely plant physiology & biochemistry, plant anatomy and the experimental methods used in these disciplines. Over the last 6 years I have especialized on mathematical modelling of plant transport systems (membrane transport, phloem and xylem transport) for which I used Mathcad as my main tool for solving differential equations. Also, on the experimental level I have experience on isotope labelling, electrophysiology and the standard methods and equipment used in those fields.  less

    Have some question that requires a statistical or machine learning answer? No problem. As a data scientist with 15 years of experience, I have the technical knowledge and the communication skills needed to solve your problem and, most important, give an answer that you can apply to your field of interest. What I offer to you is a full data analysis/machine learning stack, including: - Getting and organizing your data. - Selecting the most relevant statistical or machine learning technique for your case. - Applying the technique to your data. - Writing a report that explains every step taken and makes a interpretation of the results. All written with enough technical detail, but that doesn't require a depth statistical knowledge to follow. - Assistance in applying the results to your specific field. I can do all this using any or several of the following: R, MATLAB, Python, MySQL. Everybody can apply an out of the shell statistical algorithm to some benchmark data. But I'm an expert in the tricks needed to apply those algorithms to real data.  less

    I'm an overachieving business-savvy data magician and a natural problem solver. In my free time, I code and analyse stuff. Why not do it for you? I have been a Business Consultant / Efficiency Advisor for the last 5 years, a job that I "augmented" with analytics and programming as often as humanly possible. This has led me to start my own consulting firm. I mostly use Excel 2013 (w/ VBA and PowerTools) and Python. Alternates are R and Tableau... or pretty much anything else that can be learned. My current projects focus on Data Science in general (elm.bi and datafra.me).  less
