Experience

Minesweeper Game

https://ravanscafi.github.io/minesweeper/
When I was learning React, I decided to create a pet project to guide my studies. This game is what I created based on the original Windows game with the same name. I've basically used the create-react-app set up and developed it with pure JavaScript/React code with some CSS and emojis. I came up with my own engine logic. The game is open-source, and the code can be found on GitHub.
