Sergey Malyshev is an IT specialist from Ukraine. He has been working in the IT industry for more than 15 years, eight of which he has devoted to the development of web applications. Out of the 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 is not only a developer but also an architect, a project manager, and a technical consultant. Apart from his participation in realizing some technical projects, he also organized various advance training courses for IT specialists in the companies where he was employed. As he has a degree in management, Sergey has taken part in the business process automation of companies specializing in software development.

At present, Sergey is working as a software engineer in the company Sugar CRM and deals with the development of one of the most popular customer relationship management systems in the world. Before this he worked on developing applications based on the Yii Framework. Some of them are the search engine for the real estate website LivingThere.com and the corporate CMS system WebModulite for the New York design agency Blue Fountain Media. Participation in these projects and also work on his own extension for debugging the Yii application's Yii Debug Toolbar has helped Sergey get vast experience and expert knowledge of the Yii framework.
