About us


This is my site-portfolio, where you can find projects, programs, ideas, which were (or will be) implemented in life.

A4business — is a label of projects, which are created for everyone who requires them in business.

Most of our projects I’ve done are for telephone industry, however, as every company requires different type of application in business, after creating core system, (VOIP billing/routing platform) each time there is a need to organize company mail exchange server, CRM system, monitoring and, of course, to make it work together.

One can order commercial and multifunctional system, others could find good balance in price/quality/functionality with open-source. In both cases there are plenty of work — commercial systems usually won’t work exactly like business needs, and a lot of adjustments have to be done by custom plug-ins. The open-source is like an art of sculptor — start with a billet, and end-up with needed form and contents.
