    PERSONAL PROJECTS Snake I completed this during project week in my coding bootcamp. The inspiration came from the lack of knowledge in the younger generation of my family about video games in the 90's. I replicated Nokia's Snake game using TypeScript. I used useState to oscillate the color of the snake. Also used React to render an old computer image to display the game on. Imported an audio-player to play nostalgic retro music. Giving the user delightful feel of the game. Recipe This was the first Full-CRUD application I had built. First I started with making it a FLASK app. I wanted the users to be able to login and register into my app. To protect the users passwords I used FLASK-BCRYPT. With the use of JINJA2 I was able to optimize my HTML tags. To display multiple users and their post dynamically. As well using MYSQL as the database to store the user's information. Pirate's Cove This application I take pride in because I show cased my skills in my coding bootcamp. It was the final exam for JavaScript MERN, I utilize BootSwatch to style my app. The app allows users to create a pirate and display their images and posts. Using React I was able to create the content and display it, while using MongoDb as the database to store users's pirate information. For testing I used Postman to test my API calls. This application also uses conditionals and dynamic routing.
