First mern stack project as a fresman!

Hi everyone! I am currently in my first year of engineering and just built my first full-stack project while learning the MERN stack! It's called Statsly a website to track your Codeforces streak. I built it because seeing that streak grow gives the dopamine and motivation needed to show up every day and keep solving questions. Throughout this project, I learned a ton: The overall architecture and flow of a full-stack applicatio n. The deployment process (I actually faced some tough issues during deployment, but managed to work them out eventually!). I would really appreciate it if you could look into my project and guide me on how I should proceed ahead in my career. What should I build or learn next?
