Specialist on Bitrix

Looking for an experienced specialist, working with Bitrix. Please respond only those who know this cms , including able to work beyond the scope of package solutions. The primary task is to find and offer solutions to problems with the loading speed of the online store. (perhaps the problem is in the hosting settings), please respond to only those who are willing to take on this task and can proceed to deal with today. Write directly in the response – are you ready to start today.

Further implementation improvements. If it works out, will continue with other projects. Not looking for an Agency, but a private specialist.
