Started programming when it wasn't mainstream yet. Moreover, when most people saw a computer only on TV, and phones still had discs and wires. I taught my computer science teacher how to program, and the professors at the university kicked me out of lectures because I corrected their mistakes out loud Crazy experience in programming business applications My programs work at enterprises from self-employed to corporations with several thousand employees (most corporate systems are under DNA) Any relational and noSQL databases I love difficult tasks and new challenges. There are no tasks that cannot be solved, there are only time and budget constraints All my programs have a lifetime guarantee - any error is corrected without any time-limits

Hello. I do design because I’m not happy that when I go to a website I have to fill out 20 unnecessary forms or look for a description of the product and an argument for why I need it and from this particular company. The time when websites did not have functionality for business is over. There is a misconception that web design is just about pretty pictures. I don't agree with this! After all, high-quality design solves the user’s problem as quickly and easily as possible with a minimum number of actions for him; It also solves business problems in a comfortable format for the target audience. This is how I see web design. It is important to create high-quality websites and interfaces that you would like to use yourself. I achieved what I have now thanks to fruitful work. For me, productive work is a path of unlimited achievements that requires me to demonstrate such qualities as creativity, determination, and willingness to deal with any failures. This is not an aimless repetition of certain “working” movements. It is a conscious and rational creative process. I always take responsibility for the results of my activities. I am honest with the client and expect the same from him. I use all my knowledge and skills to create high-quality designs that I can be proud of and could use myself. My specializations: - Turnkey website creation - Site design - Layout (HTML5, CSS3, JS) - Integration with CMS (MODx, WordPress, OpenCart/OcStore) - Landing Page - Online store - Business card website - Promo page - Interface design - Prototyping Write to me if you are interested in cooperation.
