Projects

Some of the projects I made in the past years. These don't include internal tooling, private projects, or any other non-public work.

sample project image - Go HTMX Front end Template

Go HTMX Front end Template

https://github.com/FelipeAfonso/go-htmx-starter In need of a performant application for my work, I created a template for a Go HTMX application. It leverages Vite for Hot Reloading and bundling, which also makes it much easier to create isolated islands using other frameworks (like React) in specific locations of the website. It worked out great, and I used it daily during my work at ContactAI.

Spooder Game

https://king-cod.itch.io/stupid-spooder-game I crafted a simple game using Rust and the Bevy Game Engine. It may be a small undertaking, but I developed everything, from sprites and music to interactions.

sample project image - HTMX Tailwind Gleam

HTMX Tailwind Gleam

https://github.com/FelipeAfonso/gleam_htmx_tw I created an HTMX-driven web server for the functional programming Gleam language. This open-source project is a code template with built-in tailwind support, hot reloading, and componentized templating.

Prague Monitoring App

The Prague Monitoring App, a React Native app for Android and iOS, was developed with practicality in mind. It aimed to monitor pests and plagues in farms and their fields, with an 'offline first' approach to accommodate the limited connectivity in these areas. As a map-centric app, we built extra features on top of Google Maps API, ensuring its usefulness even in remote locations. While the app is not yet available to the public, it is already making a difference for farmers and agronomists associated with Santos Lab.
