My name is Stanislav Brovin and I'm ex developer of the "Alt-team" company. I have wide experience in CS-Cart development (more than 3 years), including difficult shipping and payment modules.
We have long experience in cooperation with Stanislav. His technical solutions of our tasks are quite smart and effective. He made for us many addons, integrations with some payment and shipping service, tools which have been made by this developer make our store administration work much easier. He works fast and needs very few time to understand the task. We highly recommend him for those who need any kind of cs-cart development.
