i need a developer

Exchange Site Project

We need is a fully, functional and secure crypto exchange. Example bitcoin exchange [url removed, login to view] , [url removed, login to view]

Our system should have four major cryptocurrencies: Bitcoin, Ethereum, BCH, Dash, LTC

Modules we need:

1) A user account system that allows users to register, maintain a balance, deposit and withdraw BTC and other currencies, also place buy and sell orders. Integrate this, with a payment processor to support currency deposits and withdrawals.

Users can fund account with via Bank transfer, Cash deposit, debit/credit card. Users can also withdraw funds to bank account

User account should be limited pending KYC full verification for Email, phone, ID and Address.

2) A matching engine that looks at the current buy and sell orders and matches orders together and executes the trades.

3) Develop an android app that is simple and user friendly bug free like Luno app.

Some challenges:

You need to track each user's Bitcoin balance so you'll need a way to keep the Bitcoin wallet in sync with a database like MySQL or MongoDB. A good way to do this is to combine the blocknotify command with the listsinceblock() JSON-RPC call.

Tech Functions Recap:
