Yes, we are working with different CMS, and also had develop our our CMS.
Before we were using Just-CMS as a fork of GetSimple CMS. Not we still recommend this CMS for small and fast websites – corporate, sales page, promo site, etc.
Instead of Just-CMS we start to use also WordPress as the most stable, secured and easy-to-use and develop platform. WordPress can do really a lot! And we are really happy of it!
Sometimes we are working with Joomla! CMS, but it’s not really something we like.
Russian market of web development is kinda different from World around. And instead of WordPress for russian customers we using sometimes Bitrix and NetCat. We can do also some other CMS.
With Bitrix, actually, we have partnership, and we using in our work their CRM – Bitrix24. Here our partnership certificate:
We also using frameworks – YII, Kohana (before) and Laravel. We are very close and warm also to CakePHP.
