The main client’s request with this project was speed. The website had to be delivered in under two weeks. It had to include a trade calculator, order creation, management capabilities, support for multiple user groups, automatic update of exchange rates, a telegram messaging bot for notifying operators about a new trade order, and a slight change of the exchange rate in the exchange favor by a specified percent.

To fulfill all the requirements in time, the WordPress CMS was chosen for the project as it provides back-end infrastructure and support for multiple user groups out-of-the-box. Even with a tight deadline, I could implement all of the features on a decent technical level and 100% on time.

ex3s.io is a cryptocurrency exchange platform where users can create exchange orders that will be processed manually by an administrator. The website consists of the main page and an order page with four steps. Most of the website’s functionality lies in the exchange system.

The creation of a new order consists of five steps. The first one is an exchange calculator that is placed on the index page. It allows users to put in the desired currency they wish to pay and what currency they would like to swap. The user may also swap the direction of the trade. The calculator will automatically adjust all numbers in all cases. Order validation is also present, and invalid orders cannot be created. The exchange rates on the website are regularly and automatically updated.

When users decide which pair of currencies they would like to trade and click the “Start Exchange” button, a new order is created. The order has four stages. All of the order’s information is stored and updated automatically. Once the order achieves stages three and four, a telegram bot notifies the website team so that the order can be processed as fast as possible.
