    Python programmer specializing in web scraping

    Australia - Tests: 2

    hello there, Since 2008 I have specialized in web scraping and automation. In that time I have gained vast experience working with websites that require parsing JavaScript/AJAX, using proxies, solving CAPTCHA's, and contain millions of records. I use Amazon's EC2 for my web crawling infrastructure. I can provide scraped data in whatever format is required: CSV, XML, MySQL, etc. (Most clients prefer CSV.) Much of my web scraping library is open sourced to make sharing solutions with clients easier: http://code.google.com/p/webscraping I also make websites that run on Google App Engine (free hosting) with web2py. I speak native English, fluent Esperanto(!), and a bit of Korean and Japanese. Feel free to contact me to discuss your project. Note that I will not work with adult related websites.

    Sergei Basharov

    JavaScript/React/Angular/D3/CSS3/HTML5 Frontend Developer and Designer

    Russia - Tests: 9 - Portfolio: 11

    As a practicing consultant and developer, I put substantial thought as into organizing the whole project, so into structuring the code in the specific parts of the app. The stage of setting a project basement is as important, as the development process following it, putting the team on a healthy productive path. As a result, the project earns its fat-free shape, allowing team members to focus on their tasks, not on working around conceptual inconsistencies or fighting with resurrecting issues. When it comes to actual development, I choose to write compact, isolated code. Ubiquitous well-written tests are what makes me sleep like a rock, my clients feel in good hands and safe. That’s why I put tests at the top of my priority list. The role of tests becomes crucial in the world of JavaScript. The language with its long curved path of evolution, is far from being free of quirks. Some are just unobvious and others are totally bizarre. To keep the grade of monkey business low and productivity high, I follow the best practices, use patterns where appropriate, learn new techniques and demand myself and other team members deliver quality code which conforms to the high industry standards.

    PHP Web App Developer: Any Framework, APIs and UI. 15+ years (USA)

    United States - Tests: 6 - Portfolio: 12

    Since 1998 I have developed dozens of web applications focusing on a wide-range of industries including custom search engines, affiliate marketing, real estate solutions and worker safety. As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, clean code and representing my craft to the highest degree possible. On the server-side, Laravel is my current PHP framework of choice, although I am comfortable working with Zend, CodeIgniter, Cake and Yii. For the database layer, I have 14 years of experience with MySQL. On the client-side, I prefer jQuery, Backbone and Twitter Bootstrap. Although I am not a graphic designer, I know my way around the Adobe software suite. I write standard compliant HTML5 and CSS3. I have an eye for useable, clean and obvious functionality. I have experience with many APIs, including Amazon, Box.net, Infusionsoft, Facebook, Twitter, PayPal, eWay, Authorize.net and Google. I can write APIs from scratch and give your application a RESTful interface. I am seeking opportunities to build custom web applications from the ground up or taking an existing code base and improving upon it.
