Juan Carlos is a hands-on person who likes to play around and tweak things, especially processes and the infrastructure that connects them. He tries to document as much as possible and enjoys using RDoC, Javadoc, and JSDoc as much as possible, but he adjusts naturally to whatever the project's preference is.

My Finances Progressive Web Application (PWA)

https://hellz-satans.github.io/finances/
A privacy-focused, client-only PWA to keep a record of expenses. Easy to use, easy to erase.

It's a front-end application written with Vue.js storing data in the browser's database using Dexie.js and mostly Creative Commons images for icons.

Recycling Materials CRM

A Ruby on Rails full-stack application to store and visualize recycling opportunities of a larger project.

For the front end, I used Vue.js and VueX with Webpacker connecting the build process with RoR, PostgreSQL, and PostGIS for geo operations.
