Head of the support team for the Carefusion: Rowa automated pharmacy storage systems (Rowa Vmax, Rowa Smart) installed in Russian Federation.

Integrated several software systems for Project Management, CRM, Network Management and Monitoring, Web hosting management.Upgraded Asterisk based solution to the Freeswitch based softswitch platform for the VoIP telephony services.Optimised network topology - reduced leased lines costs, implemented new softswitch solution for VoIP services.

Upgraded wireless network from fixed to mobile WiMAX (in 3,5GHz band) in 33 cites.Developed all the needed documentation for Federal Service for Supervision of Communications, Information Technology, and Mass Media (Roskomnadzor) in order to upgrade wireless spectrum licenses that used IEEE 802.16d equipment to the new 802.16e mobile WiMAX versions.

Tweaked Android OS for different Android based tablets. Full Android OS stack (including Linux kernel) was ported to several handheld systems.

Developed software-based network models for WiMAX and FTTB projects. Completed several trials of wireless equipment. Provided technical data for WiMAX and GSM spectrum applications.

Participated in system integration projects as the wireless networks expert in microwave systems, Wi-Fi, fixed and mobile WiMAX, TETRA, GSM, CDMA2000, UMTS and DVB-T systems.

Linux kernel ported to Siemens SX1 as a first reference device. MACH_SX1 support is included in mainline linux kernel.Developed some of the core components for the complete linux-based GUI system for mobile smart phones: gsmd (GSM services daemon), tbus(tiny message bus, modelled after D-BUS, but much simpler), parts of the phone interface, using FLTK widgets library for Nano-X window system.
