    Jason M.

    Expert Developer, Thought Leader

    United States - Last active: 09/18/2014 - Tests: 7 - Portfolio: 5

    I have been developing cutting edge software for over twenty years. My experience has been centered around ultra high performance embedded systems as well as modern web design and programming. I have been intimately involved in every aspect of the development lifecycle, including: brainstorming, requirements capture, resource management, graphic design, programming, testing, deployment, even sales and marketing. All of my projects are extremely thorough. I am more driven by the quality of my work than I am by the hours I will bill. I am also an entrepreneur and have spent plenty of time on oDesk on the other side of the fence, so I understand exactly what employers are looking for. That is why I am confident I can provide unprecedented value.

    Italy - Last active: 1 day 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!

    Bill Demos

    Software Architect

    Greece - Last active: 04/28/2014 - Tests: 3 - Portfolio: 6

    I finished my degree, BSc Honours in Computer Science at the University of Leeds, England, at the age of 22. Since then I have had more than 15 years of experience in building large scale applications using Delphi, C++ Builder, Microsoft VB, Microsoft C++ and Microsoft C#. Other skills involve 3D programming with DirectX, OpenGL, and HLSL. I have a very good physics and mathematical background which allow me to easily develop physics simulation systems, 3D visualisation systems and deal with problem solving. I can easily program client/server multitier applications that involve network communications such as TCP/IP programming, SOAP and a lot of other proprietary and standard network protocols, such as POP and Web Services among others. All application programming at some point involves storing data in a persistent storage. I have been writing applications that span over from custom database development, such as binary tree/hash tree indexing units, to using ready made relational database systems such as SQL Server, Interbase, Oracle and Access.

    R&D Software Consultant & Engineer

    Ukraine - Last active: 05/20/2014 - Tests: 1

    That's all about boutique software consultancy and engineering. Hi-End full-cycle services in analysis, planning, research, UI/UX, design, and development. I am an experienced software engineer and project lead with a solid background both in core Computer Science/IT field and hands-on consulting/analysis/research/engineering. With 7 years of intensive commercial and academic experience, I have mastered agile/lean web development, object-oriented analysis & design, and component-based software engineering. Moreover, I do believe education matters for the mindset and overall professional abilities. I have an excellent M.Sc. degree from top national university and at the moment I am doing my postgrad studies pursuing a Ph.D. In addition, over the years I have set up my own professional style and methodology, reinforced with communicative and organizational abilities. Curious analytical mindset and moderate perfectionism are the core of my approach to problem solving. After all, Ukraine is really a rich country in terms of brainy and skillful IT people, and I have a broad professional network, as well as a great multifunctional team at hand. Thus, potentially you can get proper resources for a complex problem, on demand. Therefore, I am able to provide you with a unique hi-end service in building software solutions to tackle your problem domain. I think the greatest thing you get here is an artistic, boutique attitude rather than a straightforward confined execution.
