My team and I decided to create a platform for searching for a

work as a start-up project. Our team consisted of 2 back-end
LinkedIn developers (on Spring framework), 1 WordPress developer as

Skills so in addition to improving my programming skills, I gained some
experience in managing a small team.

In this project I used such stack of technologies as: Spring Boot

SQL (PostgreSQL, AWS EC2 instance for deploying back-and part, S3 service for
MySQL) keeping les from users and RDS service for deploy our database.
Nowadays, this project is still in development, especially front-end
