I worked as a full stack developer. I participated in the development and design of the database, the server part of applications and refactoring the already written part of applications. During the period of work, I worked with 4 applications, which in the future were to become parts of a large project. I directly created the administrative part for the already existing application and was the leading backend developer in one of the two most important applications for the project. Including constant communication with TeamLead and UI developer, respectively, there was a review and refactoring of the code, which improved my respective skills.
