A good portion of the project is already completed. Our budget is 200€-400€ and the project deadline is exactly no later than 26th of May. More information about the project is in the .pdf file. Our priorities are security then convenience and finally, optimization. This project is about creating the backend infrastructure (preferably with NodeJS and MySQL) for a cryptoexchange that involves both fiat and crypto currency. Additionally, a payment gateway (Paypal, ERC20, Bitcoin) will need to be implemented as well. As previously stated, part of the work is already complete: a good chunk of the database is structured, an algorithm for finding optimal exchanges is written, and some very basic web3js manipulation is present. For those interested, I recommend reading the .pdf file. We have intentionally made parts of the documentation ambiguous to hide important project characteristics. However, we will share the information with those interested in partaking in the project.
