    Sencha Ext JS Expert

    Russia - Last active: 1 day ago - Tests: 2 - Portfolio: 4

    Full-time freelancer. The last 5 years of my career I have worked with products of Sencha (Sencha Cmd, Sencha Touch 2.3, Sencha Charts, Ext JS 3.4, Ext JS 4.2, Ext JS 5.x). I was fortunate to work with highly diversified range of tasks. The list includes: - upgrades of applications (Ext JS 3.4 -> Ext JS 4.x -> Ext JS 5.x), - mobile application development (Android, iOS, Sencha Touch), - using Sencha Charts, - integration of third-party libraries into Sencha products (OpenLayers, Highcharts, jQuery, Google Maps, Yandex Maps, Telerik), - code testing in Selenium, Siesta, Sinon, YUI 2, - refactoring, - fully project reimplementation (rewrite a project from scratch, rewrite a project from JS to CoffeeScript), - consultations, - and much more. I work in a team as good as one. I have success experience of managing a team of 7 developers. I am a great UX architector, thanks to the long list of successful projects and deep knowledge of the subject area. Most of my projects was big (up to 30 people on the project) and it taught me discipline, scheduling of work time and reporting a progress. First of all I am interested in large projects and in the position of a leading developer, so I can use the experience gained and to feel comfortable for a long time. Javascript is one of the few languages that gives too much room for creativity, a space to express their thoughts. And unfortunately too easy to go far from the correct direction, from the decision to be easy to understand for other developers. That is why I firmly believe in the need to using hard coding standards and official recommendations. It's not important that you are using for your projects - PHP, RubyOnRails, C#, Ajax, XML, JSON, bla-bla... I just said you: Yes, I can do it! It's OK! I know well Git, worked with Subversion, used many task trackers: Jira, Redmine, YouTrack, and others, can't remember all.. Also my expirience included development of a mobile apps using Java for Android. If you need in one of the best, you're welcome!

    Software engineer and developer

    Austria - Last active: 1 day ago - Tests: 4 - Portfolio: 2

    During the last six years of professional working experience I gained a full understanding of the life cycle of software development. I especially enjoy studying new technologies, programming and implementing solutions - using the existing APIs and frameworks or developing solutions from scratch. I am able to work as a part of a team or deliver solutions independently. Development of business Web applications using Open Source technologies is the area where I am intensively working. Special skills and knowledge that I have are in using of Sencha Touch Javascript/HTML5 framework for developing user interfaces of Web mobile applications, as well as Sencha ExtJS Javaswcript/HTML5 framework for developing user interfaces of web business applications. MVVC, MVC and event driven SOA client-side application architecture are well known to me. Further, I have a good knowledge in Phonegap with packaging and signing native mobile iOS and Android applications and with automating build process In addition to client-side development I also completely understand the three tier Web application architecture. As a result I have professional experience and knowledge in developing server-side Web application using Java technology. More specifically it relates to Spring (MVC, WebFlow, Security, Transactions) for the development of the middle tier, JPA, Hibernate and MyBatis ORM platforms for communicating with the database and also PLSQL / SQL to perform queries on Oracle, PostgreSLQ and MySQL databases. The key strengths that I possess for success are that I strive for continued excellence and investing in knowledge. I'm a dynamic, optimistic and a responsible person, who likes to face challenges.
