    Senior Ruby on Rails Developer, Technical Writer, Translator

    Russia - Last active: 12/27/2014 - Tests: 6 - Portfolio: 4

    Hi, my name is Denis. In a nutshell, I am senior Ruby on Rails developer with hankering and aptitude for creating user-friendly and highly-functional websites using the vast array of state-of-the-art yet already proven technologies. I am experienced in both back-end and front-end levels. Chiefly, I follow the MVC approach utilizing Ruby for controllers, MySQL or MongoDB for models, and HTML5/CSS3/JS for views. I also ably utilize the following technologies: — CoffeeScript — HTML and CSS template engines (HAML, Slim, SASS) — JavaScript libraries (jQuery, AngularJS) — Database engines (SQLite, Oracle) — Version Control Systems (git, mercurial) Besides, I have been working as a technical writer and translator for over 3 years. This experience substantially helps me in my website development activities because producing user's guides and manuals helps me better perceive users' preferences and needs so my end product is always highly customer-oriented. Thank you in advance for your time and consideration. I look forward to working with you soon!

During the period, I acquired many experiences that I use various mobile development frameworks and I became an expert engineer with expertise of the mobile applications. -iPhone/iPod/iPad, Android, Web Service,Ajax,XML,JSON,RSS,SOAP,WSDL -Social Photo/Video/Music App(Video/Audio Streamming,Photo/Video Editing) -MySQL,SQLite,HTML5,PHP,JSP -Facebook,Twitter -Location Based App(Google Map Service,Foursquare) -CoreData,CoreGraphics,Animation -Flurry,Testflight, lira, Basecamp, Dropbox If you are expecting such words as "High Quality", "Clean Code", "In Time Delivery" I would be the right person. If you can stand with "Memory Leaks", "Often Crash", "Low Quality", "Postponing the delivery" then I'm not your choice. I always try my best to be in the same line with the high technologies. You will be reported with the intermediate deliveries and project status every day and you will be able to take control over the whole progress. I can provide you with free bug-fix support for 1 month after submission of the app to the App Store. And if my project is not satisfied for you, you will be guaranteed 100% money back soon.
