MARCO ARBOLEDA

This is an inventory management app for an imaginary grocery store (design inspired by Walmart's online grocery section).

I created this with the help of Node.js, Express, MongoDB, and React.

This was my first time using React with a back-end database and I learned a lot in the process, such as making API calls in the useEffect hook to simulate the same behaviour as lifecycle components.

This project also helped solidify my knowledge of doing C.R.U.D. operations (Create, Read, Update, Delete) on a back-end database.

This is a memory game where you have to repeatedly choose from a set of cards portraying characters from the Tekken video game franchise without choosing the same character twice.

This was my first exposure to using React Hooks, and I found them a lot easier to set up and use compared to class-based components.

I used React's state management to keep track of the order of the cards, which cards have already been selected, and a tally of the player's current score and high score.

I also made use of the Fisher-Yates shuffling algorithm to shuffle the cards. This is an efficient algorithm as it does not need to create a second array (meaning it is space-efficient) and the runtime is O(n).

This is a Tic Tac Toe game created using vanilla JavaScript.
I made use of the Factory Function and Module design patterns to create this app.

One of the most fun and challenging parts of creating this was the optional goal of implementing a computer AI that is impossible to beat (i.e. at best, you can make the game end in a draw)

I learned how to implement the Minimax AI algorithm for this type of game which also gave me an opportunity to practice recursion.
