As a Node.js developer, I worked with NestJS + MySQL to create and improve APIs and services for a product aimed at the WEB2 + WEB3 world of music, courses and other elements. The entire development of the product was based on the SOLID and Clean Architecture principles. To guarantee the quality of the services, I developed unit tests using Jest, identifying errors beforehand and protecting the API from such failures. In addition, I used Swagger to build the documentation for the services built, guaranteeing the quality and reliability of the data sent and received.I also mentored an intern, teaching him the best programming principles, as well as the basics of good code and software architecture. I was responsible for its total development from the beginning to the end of my activities, teaching and also learning from it.Technologies used: NestJS - TypeScript - MySQL - PrismaORM - Redis - Rest APIs - Swagger - Docker - Jest - Git
