Developed a cryptocurrency exchange using Waterfall methodology.

I worked as a back-end developer on the crypto team, making everything related to crypto payments and monitoring systems possible. While at Paybis, I integrated different cryptocurrencies, tokens, and smart contracts using APIs and various libraries, and sometimes even created and adopted usable libraries for PHP by myself. In addition, I completed an average of three to four code reviews a day.
