    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: 3 days 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.

    Multidisciplinary Consulting Expert with Fortune 10 Experience

    Sri Lanka - Last active: 15 days ago - Tests: 92 - Portfolio: 5

    HOURLY PROJECTS ONLY, Please! And no time wasters too, please! I work ONLY with clients that have both a professional attitude as well as a prompt payment ability. Hi: Thank you for taking a few moments to glance over my oDesk profile. I possess an excellent command of English (it happens to be my native language!), verifiable accredited U.S. qualifications, authentic Fortune 10/100 work experience, as well as a powerful portfolio of specializations, skills, experience, and capabilities. Although I've passed over 90 oDesk tests and more than 27 Brainbench tests, I regularly add new skills to my portfolio. AREAS OF EXPERTISE: Advanced Project, Program and Portfolio Management (SCPM - Stanford) Business Consulting - Leadership, Management, and Technnological Management of technology Organizational Behavior Organization Design General Management Business Analysis Systems Analysis Marketing: Penetration of new market segments Design of Tests and Examinations - including Psychometric Evaluation Quality Management (CMQ/OE: ASQ Certified Manager of Quality / Organizational Excellence) Quality Engineering (CQE: ASQ Certified Quality Engineer) Software Quality Assurance (CSQE: ASQ Certified software Quality Engineer) CMMI ISO 9001, SPICE, TickIT and other Quality Standards SDLC / Agile Software Development Methodologies Software Technologies and Development Environments Multidisciplinary Training - Individual and Groups GRE and GMAT Examinations Coaching I have a working knowledge of a broad range of software across a wide range of industry segments (general management, international quality systems standards formulation, market penetration, manufacturing, financial services, customer service, training, software development, systems implementation, systems analysis, systems certification and accreditation), together with primary and secondary research capabilities. As far back as 1994, I designed, developed and successfully implemented across several sites, a Refinanced Loan Management System (RLMS) while serving as the joint Management Information Systems Expert and Computer systems Specialist for the SFLCP project funded by the International Fund for Agriculture of the United Nations (UN / IFAD) and the Canadian International Development Agency. During the relatively short period of July 1996 to September 1997, I designed, developed, and successfully implemented what was probably the world's first ISO 9001-compliant Quality Management System that allowed new technology platforms to be added without the need for immediate re-certification. What all this means to you is that you finally have the ability to economically hire someone who is quite comfortable delving into even the smallest details while simultaneously monitoring the "big picture," ensuring you get the most from whatever your assignment requires. Of course, I prefer to work with clients who look forward to taking their companies to the next level in terms of performance, profitability, as well as corporate responsibility. Stay tuned for new skills, technologies and achievements that I will be adding to my portfolio in the very near future. Sincerely, Prasanna L.L.
