This project is about building a cryptocurrency exchange which is full functional but has no great features. That means it does the minimum an exchange should do: buy, sell, withdraw and deposit cryptocurrencies and provide information. We're looking for a talented team of coders who are experienced in heavy load applications and API building. The project consists of the following parts: * Frontend Development / Web Client (Browser) * Backend Development / Wallet- and Transaction Management * Server Infrastructure / Scaling and Caching More Information on Frontend Development * Focus is on Usability - a wonderful webpage does not help if its slow. Still we would like to have a Single Page Application for the exchange page * Angular4/5 is a plus but not a must. As long as you know how to strip down all unnecessary parts of the bloated framework code which is delivered in standard builds. * Standard landing page, nothing fancy (maybe webm) * User Registration, Login and Settings * Support Page with Customer Ticket Management * Balances Overview and Withdrawal * Exchange, ... ... some words on this one: There has to be an extra navigation which is an overview of all currency pairs that will be traded on the exchange. The pairs must be listed with current price, volume and percentage for each one. The main part of the exchange view consists of: * a candle chart (must work on live data) * a form to post a buy order * a form to post a sell order * a list of the trade history (must work on live data) More Information on Backend Development * You should know Python / Django / Django Channels / Django REST framework * Live data will be streamed through web sockets (ticker, history and order book) * All other calls can be simple GET/POST (still order of incoming calls must be conserved) * Session Authorization * Wallet Management (basically withdraw/receive to a certain wallet address and track user balances) * Transaction Management, this is an extra bullet point because its crucial to handle some database transactions atomically when working with the money of customers. Please keep this in mind More information on Server Infrastructure: * Postgres Database Cluster * Memcached or some other cache * uWSGI should be good but not a must * nginx is a good choice, it can scale very good if configured correctly
