A deep look into the foundations of modern AI, starting by building up the mathematical intuition for backpropagation, then using this knowledge to implement a convolutional neural network.

The network is then trained on MNIST, achieving 85% accuracy.

A deep learning research project where a model was trained to solve tasks from François Chollet's Abstraction and Reasoning Corpus. The model was based on and inspired by previous work on neural cellular automata.

A Unity package that allows the user to reduce the polygon count of any mesh, featuring a real-time slider. The tool produces reliable results without significantly noticeable artifacts, even when reducing a mesh's vertex count to less than half its initial value.

A game built with the Unity game engine, featuring competitive multiplayer in a procedurally generated world.

I am fascinated by how much is involved in making a good game. There are endless things to consider. Some things I have worked on so far and have written about are a procedural generation (https://marcospereira.me/2022/05/10/a-simple-hash-for-perlin-noise/) and multithreading (https://marcospereira.me/2022/05/06/safe-async-tasks-in-unity/).

A detailed study of an everyday utility used in game development: the linear interpolation function.

I mainly wanted to work on my math visualization skills and make equations and graphs look good on my website.

CharityTab was a fully customizable new tab page, available as a web app and browser extension. It allowed users to donate to a charity of choice by viewing ads and shopping through sponsored bookmarks.

A productivity tool that disabled Twitter's infinite scrolling feed and replaced it with a "Show More" button. This project was deprecated due to the high maintenance required to keep up with regular updates to Twitter's web user interface.

A Chrome extension that allows multiple users to synchronize their streams on a popular streaming service using an intermediary Node.js server.

When users join a room by name, their stream will automatically be synchronized with others in the same room. If a user pauses the player, everyone else's stream is also paused.

A twist on the mobile hit game where the player must avoid crashing into obstacles in an infinitely scrolling world. Built from scratch with a custom fixed-timestep game engine based on HTML Canvas technology.

A set of custom modules written for a popular Twitch bot that allows users to duel and gamble the points they earn while watching their favorite streamers. They were developed in JavaScript and deployed using Heroku.

A link shortener and web status checker built in PHP. The link shortener was built to encompass two domains: the host domain that allows the user to minify links and a short domain that redirects the shortened addresses to the correct endpoint.

A 2D top-down puzzle game where the player pushes crates around in a grid with the objective of filling all the predefined storage locations. This project is written in Haskell and uses the Gloss vector graphics library.
