    Alexander T.

    Software Engineer

    Ukraine - Last active: 1 day 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.

    Gabriel L'Heureux

    Business Consultant

    Canada - Last active: 4 months ago - Tests: 6 - Portfolio: 2

    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).
