Redesign + improvement of functionality

Good afternoon.
The site is written in php+mySQL using Ajax+js
The project is being run by a bot on node.js
Api is actively used by a third-party site.

Need to:
Add a personal account:
1) Inference of a nickname (take from the mySQL database)
2) Derivation of the number of wins (take from the mySQL database)
3) Total amount won (taken from mySQL)
(4) Withdrawal of inventory - not implemented. Working with Api
(5) Withdrawal of the number of points earned (not realized)

Integrate chat:
1) Chat written
(2) Replacement of the regulars (Russian fix)
(3) Str_replace - clear of links and debris
4) Adding functionality (working with mySQL database)

Development of integrity control and ticket script:
(1) Model writing
(2) Integration
(3) Debugging

Fixing small bugs:
(1) Str_replace work - not everywhere clearly processed symbol ' - for example in the nick "I'm GOD" or in the name of the subject - "Man'O'War";
(2) Refining the output of the message on Ajax
3) Reworking of statistics on the site
(4) Testing and debugging of all systems to reduce site load and optimize scripting.

Redesign of the site:
1) Drawing a layout based on the "Wo, V, this site I like, I want the same";
(2) Tape + stretch.

Ideally, you need a permanent freelancer who will study the engine – there is work all the time, there is a lot of it every day.

Thank you for paying attention to this project.
