I am a self-taught computer programmer with more than 20 years of experience in a variety of fields, including Asterisk PBX development, PHP, Android, .NET Framework, MSSQL, MySQL and Linux. Implementation of many professional IVR systems, including Telephony Games, Entertainment services, Tele Advertising systems, are some of my experiences in the field of Asterisk PBX development. All of these services are currently under use in high capacity systems. Designing and implementing “IVR Management Portal” using PHP and especially using the Yii Framework is my experience in using PHP. Designing and implementing multiple Android applications, including "English Language Training" and "Seconds" game, is also some of my Android programming activities. All the mentioned systems are using MSSQL/MySQL as DB systems with millions of records. All DBs are designed and maintained by me. The dominance of the Linux OS is also noteworthy. Over the course of my working life, the use of various programming technologies has made it possible to experience working with other programming languages like PERL, Java, ASP Classic, and so on. The eagerness to learn more is one of the features that can be mentioned.
