Overall it's a small repo so my comments are not very serious issues. It'd be great to see a larger project that you worked on. Also, send me your CV so I can have more context on your experience

You probably already know some points in the feedback, but I don't want to assume that so I'm sending all my comments

Good points

• nice project structure
• good use of async/await

Improvements
