Sergey Malyshev is an IT specialist from Ukraine. He has been working in the IT industry for more than 15 years, 8 years of which he has devoted to the development of web applications. Out of conviction that it's impossible to become a great specialist in all areas at the same time, he has chosen for himself PHP, MySQL, and JavaScript as top priority directions. During his career, Sergey took part in developing dozens of different websites, social networks, CMS, CRM, and ERP systems. He was not only a developer, but also an architect, a project manager, and a technical consultant. Apart from participating in the realization of some technical projects, he also organized various advanced training courses for IT specialists in the companies where he was employed. As he has a degree in management, Sergey took part in the business process automation of companies specializing in software development.

At present, Sergey holds the position of a software engineer in the company SugarCRM and deals with the development of one of the most popular customer relationship management systems in the world. Before that, he worked on the development of applications based on Yii Framework. These include the search engine for real estate company livingthere.com and the corporate CMS system WebModulite for New York design agency Blue Fountain Media. Participation in these projects and also work on his own extension for debugging Yii applications, YiiDebugToolbar, has helped Sergey get vast experience and expert knowledge of Yii Framework.
