J. Castillo’s Web Designs and Applications
This is an app built in Android Studio/Kotlin.
Piggy Bank Virtual is a project I came up with for an interface design class. It takes input for a financial goal and calculates how many payments you will need to complete if you make a certain minimum payment and how much you saved so far. This is a web app built using Visual Studio/React and hosted on Netlify.
You can:
- add a financial goal
- add a payment to a goal
- edit a goal
- delete a goal
- display a bar chart showing the progress you’ve made on an individual goal
- display a bar chart showing the progress on all the goals in one chart

This is an app named e-NOMmerce that I worked on for Reverend Studios. The WordPress website uses WooCommerce to place an order and then using a Consumer key and Consumer secret, it connects to e-NOMmerce to display the order details.
