Thank you for reading my profile :) My name is Sergey Tamkovich, you can find me in the CREDITS file of you asterisk - i believe that says a lot about me. I love good look-n-feel, but for me the main concern is performance and scalability. If you need to speedup your existing system, or if you are looking for smart design, that will handle your growth without lags/drops etc - then you are my client :)
