    Hi! I'm a web-developer from Russia. It seems that i'm completely unable to choose a proper photo for my profile, but apart from that i'm a good specialist :) I've worked with a team of high-profile web-developers on http://www.medsovet.info , one of the Russia's biggest and ambicious medical websites. I have expirience with various web-related programming languages and technologies. My primary specialization is PHP, but i'm also rather experienced in JavaScript, jQuery, AJAX and MySQL. I've worked with CSV and XML import/export apps, developed several web-parsers, and fixed loads and loads of bugs. It seems that fixing stuff is what i can do best!

    VB Excel / Access Specialist

    United States - Last active: 3 days ago - Tests: 6

    I am a power Excel and Access programmer, specializing in creative solutions for database creation, mining, and analysis. I use VB extensively to create easy "Windows" type interfaces that allow users to interact with the data, without the need to know all the technical ins and outs of the underlying relationships. I *enjoy* programming. Its more like relaxation than work to me. Its similar to how some people might enjoy putting together jigsaw puzzles or crossword puzzles. oDesk employers have greatly varying problems they want solved, and coming up with those solutions is exciting and addictive (and the money is nice too!) Examples of past work include: a "Gamified" HR training program which encourages trainees to study and take quizzes through social interaction, leaderboards, badges, etc.; a parts ordering database with photos, employee descriptions and technical vendor descriptions, linked for automatic quotations to the appropriate vendor, and including current and historical purchase order transaction details and summary reports.
