From a simple jQuery plugin to a full SaaS business, I’ve worked on different projects over the last few years outside from my full-time job. Here’s a non-exhaustive list of them.
MatGoat
MatGoat is a SaaS product to manage martial arts academies and increase their students engagement.
It was originally created to address a real need at my BJJ academy for my teacher back in 2024, and organically became a product that expanded to other academies across all martial arts disciplines through word of mouth.
Many academies and thousands of students are now actively using it, and it’s been amazing to plan and add more features over time. Now I have a pretty complete suite of features, including payments, communications, and assistance tracking.
These days, I’m mainly focused on marketing for the product to help even more academies.

Planleave
Planleave was a simple and easy way to manage your teams time-off in a centralized place. It was a SaaS business based on Ruby on Rails and React created by me alone and was acquired.
Since then, it went on for a while but it seems the new owners eventually closed it down 🥲. The domain was: planleave.com.

Bruno
Bruno is an open source project written in Ruby and it was created as a simple tool for transforming the i18n files with translations between Android and iOS. I don’t actively maintain it anymore but I used it a lot when I developed a couple of iOS apps to share the files with the Android team.
The source code is here on Github.
Autojump
jQuery plugin to “jump” to the next input field in a form automatically after a certain criteria. This is how it works:
