    Italy - Last active: 19 hours ago - Tests: 17 - Portfolio: 1

    I am a computer scientist whose main skills are in the field of data analysis, pattern recognition, statistical software, machine learning and large scale system design and integration. I have developed systems using Neural Networks, Markov chains, Support Vector Machines in various applications: OCR, image processing, data analysis, text indexing and retrieval. I am also proficient in 3D image visualization using common off the shelf libraries and methodologies, either low or high level, like OpenGL, DirectX, VTK, Java3D. I understand and use common ray tracing programs. I understand image processing topics like segmentation, thresholding, classification. I have worked in the past in a 3d Face recognition European project. I know the OpenCV library quite well. In the field of "general programming" I have a good understanding of Databases, multi threaded applications, sockets, pipes, encryption (symmetric and asymmetric), compiler design, operating systems, low level data structure in memory and on disk, data integrity. I consider myself an expert in data structures and algorithms: trees, queues, lists, b-trees, hash tables; I use standard libraries like STL, Boost, Java generics. I have a good knowledge of SQL and data normalization however I have also used custom No-SQL databases like Datadraw, MapDB, Tokyo Cabinet, Zope. I know all the basic algorithms and templates used in every day coding; regarding data integrity and security. Compression (lossy and lossless), symmetric and asymmetric encryption, public certificates, I have worked with OpenSSL programming, encrypted web services, packet sniffers. I am proficient in all the common every day languages with an emphasis on C++ and Perl. But I can use: Java, Python, Visual Basic, C#, PLSQL, Delphi. I know all the Object Oriented Programming concepts and design patterns and I use them if the need arises, but I am also able to write object-free programs in C or functional languages (like Haskell or Scheme). I know modern version control systems like git and mercurial, even if I can use also older ones like Subversion or CVS. I know Windows programming and API quite well. I have used WPF and WCF to create desktop applications in Windows and web services. I have used Linux and Gui toolkits like Qt which are platform independent. I know XML, XSL, I have used several parsers like the MsXML or Xpath. I know how to validate a XML with a schema. I have worked with a team that handled thousands of XML documents relating to air crashes in a SQL server database. I am able to talk and write in English with fluency. If anything is not listed here either I have forgotten to list it or I can probably learn it quite fast, so don't hesitate in asking!

    Do you 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.
