Samplify - Fullstack developer
2023 – 2024
This was a personal pet project I created to learn new technologies and
reinforce my existing skills. The main idea was to build a site similar to Spotify
and implement its core functionality. I developed the backend using Express.js
initially and later rewrote it in NestJS, with a MySQL database. I implemented
modules such as the Main Page, listing all artists and allowing users to log in or
sign up. Authentication was handled with JWT tokens, generating access and
refresh tokens upon login. Once logged in, users can access their favorite
songs list and personal account information, including options to change their
password or delete their account. I also created the Artists module page,
displaying all songs with pagination.

Creating backend endpoints using Express.js, create entities,
