Senior Web Expert with Best Idea.

Ukraine - Tests: 2 - Portfolio: 7

Thank you for viewing my overview. I am web and desktop developer. I specialize in computer engineering and have 20 years of experience in this branch. After self-studying math and MATLAB, determined to continue reading computer books based on them. Languages such as BASIC, C/C++, HTML/CSS, W3.CSS, Bootstrap and Foundation had me encouraged toward coding. So , JavaScript such as DOM, jQuery AngularJS,AJAX; Server Side page such as PHP SQL ASP Razor ASP.NET; JSON/XML/XSLT/DTD/XML Schema/SVG data structure design and parsing; VB/VC++/ObjectiveC and Java applet/Android. I widely experienced that what is important in programing is not coding, but just design with optimization & higher QoS. This is why I master OOP.MVC . So, I can let you use apache,wordpress,mysql, guarantee you against any risks by consistently adhering QoS of info security (according to just RFCs drafts in IETF) . Android & Iphone app development is not an exclusive property necessary for only top freelancers. Sure I am in a position to develop front & back end APIs either. Especially the former rather than the latter. I have years of experience in media communication, GPS ,ordering anything etc. I carry strong confidence at both of quality and speed of my project. Thank you very much for reading my overview.
