Experience

Stardrop Android

https://play.google.com/store/apps/details?id=io.whitestar.stardrop

A mobile application that allows users to securely send files, pictures, or videos to a remote server that they have permission to access. I wrote the code that runs this app and created a custom keyboard interface.

Me Again Video Game

https://ladlegames.itch.io/me-again

A personal project that I created with a friend using Godot 4. The project is a puzzle platformer video game in which the player reaches the goal by making copies of themselves that they can use as platforms.

WhiteStar Shell

https://play.google.com/store/apps/details?id=io.whitestar.whitestarshell

A mobile application that allows users to access a Secure Shell interface with other machines. It only functions if the user has the appropriate permissions and a valid server-side pseudoterminal to connect to. I wrote the code for this project.

FIXD OBD2 Scanner

https://play.google.com/store/apps/details?id=com.fixdapp.two

An app for FIXD's customers who've purchased one of their OBD scanners. The app facilitates the setup of the scanner's vehicle and Bluetooth connections, directs the scanning of the vehicle, interprets the results, and displays them in a way that is easy for the user to read. I worked on this app from 2017 to 2023, and by the time I left FIXD, I had written most of the code that runs the app.
