    Software Engineer

    Ukraine - Last active: 13 hours ago - Tests: 4

    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.

    Data scientist, Mathematician, Matlab expert, Good command of R

    Germany - Last active: 05/02/2014 - Tests: 1

    Simply put I love solving real life problems through mathematics and data science is the ideal way to keep enjoying science while answering exciting business questions and turning ideas into business opportunities. As applied mathematician, I will combine my experience of interdisciplinary scientific research and of international team work. I worked in ONERA, the French aerospace lab during my awarded PhD in applied probability and succesfully at BASF in the polymer engineering department as a model developer. Besides, I have completed this experience with statistics skills and machine learning knowledge. Furthermore, I have a friendly communicative personalty. Actually, I can convey technical content in a very simple way. The clarity and the simplicity of my communication style precisely earned me the ONERA PhD Award 2011 atop the quality of my research and my publications. I know how to walk my audience through a technical problem so that the added value is seen and understood, which is the alpha and omega of creative discussion and innovative solutions. Eventually, my appetite for international environment led me to become the president of the local group of a Pan-European student network and will facilitate working with colleagues from all over the world. I would be delighted to add my skills to the success of your projects.
