Refining and checking the site

Remote work on the site. The site needs to be reworked and checked. 1. There's a website. You need to conduct an audit to optimize the work of the site – so far the site is raw and dull.
2. Run a speedtest or perform analysis through analytics or metrics.
3. Conduct a small setup and optimization of the hosting and server, as well as the Bitrix site management system
4. After these works, you need to form a TZ: what works will be carried out on the site, how long it will take and pre-assess the cost of work.
5. Access to all necessary resources will be provided
