Best VOIP Expert Available

I am working with asterisk more then 18 years. Have at least 15 years of extensive DEVELOPMENT work. My primary services are VoIP systems design, billing for VOIP, web for VoIP/reporting interfaces. I have compleated some autodiallers, including one with 20k concurrent calls, proved I can do complex modules for freepbx/trixbox, have done some a2billing contributions. Also I have experience with multi-server VoIP clusters end virtualized VoIP services, including ones in amazon ec2. -small and large VOIP system based on SIP protocol -general VoIP architecture design -web and billing for VoIP -support for asterisk, FreePBX/trixbox and a2billing, openser/kamailio/opensips. -modules and addons for asterisk, freepbx, a2billing -load-balance using openser/kamailio/opensips -virtualization with openvz, xen, amazon ec2 service. -support for linux systems and supply services for voip. -create network storage clusters, mysql replicated setup, mysql-clustered experience -per hour support and consulting for all above every finished project have free limited 10 day support&bugfixes. note, I have near zero aborted projects, most of them from client-side. I have NO "work-in-progress-forever" list like a lot of users have. so the completion rate is REAL. The only thing I not do is graphical design work, I'm sorry, but it is hard to be professional in VoIP and design in the same time. I have choosed to be best in VOIP
