To finish back-end

It is needed to finish back-end development of crypto website, which regards to gambling game – a roulette. Design, front-end and back-end’s major part are already done, but former development failed some things. Please, see the list to do below: - Deposits/Money withdrawal via api coinbase (the developer said that new api doesn’t work yet, so, it seems to be done with older api) - To make a game itself totally functioning (it is the one – a roulette, it is partially realized; node.js + redis) - To finish chat (to add smiles, and fix displaying of last 10-20 messages) - To adjust sounds and roulette functioning (when it spins, stops and new bet was made) - To make authentication with telephone number (it is also necessary to decide which service will be the best solution for it). - To make all the graphs perfect (in personal account and with different statistics) - There is auto-refreshing Bitcoin rate at home page, it is needed to add red arrow downwards when rate becomes lower instead of the green one which is default now (rate grows – arrow up, rate falls – arrow down) - To make reCaptcha at Sign up page – it already exists at Log in page - Sign up page consists some little bugs, e.g. no flags displaying near countries when picking them. Additionally, it is desirable that telephone number mask automatically adjusted to the country (now it almost exists, but not for every exact country. Now, when telephone number entering script defines a country by the code beginning, but it’s needed the code to be already entered when picking a country) - To fix an order of game numbers (for Statistics page, they are in wrong order now) - To show certain page quantity inside the Statistics: now it shows more pages than needed, with that unnecessary pages can be opened and are empty which - There is a bug: because of page making and back-end a text was displaced (there were different front-end and back-end developers) – needs to be fixed - To make admin panel safe (hide for public access, to make page access available only for administrator, Error should be shown for not logged in and common users) - To change VK icon to Telegram icon at footer - To fix sign up and log in pages: when Tab press the pointer to be set at the next field In case if there are any internal errors of user interface – they need to be fixed. So, back-end part of the project should be finished. Write your prices
