I studied radio engineering in Zaporizhia National Technical University, Ukraine. Since my diploma in 1992 I worked in telecommunications and IT industries. My experience with VoIP started in 2005. I'm author of Vapp IVR framework which allows to create multilingual IVR applications with small effort. I created a golang port of popular sippy b2bua library. I've contributed to many open source projects. Since 2006 I'm working for Sippy Software as a backend developer. I'm married and have two children.
