Sheetz
-
Developed and delivered user interfaces for two Point-of-Sale (POS) systems and one Self-Checkout solution using GK Software. Collaborated closely with the GK implementation team in a co-development environment to ensure seamless integration and project alignment. GKSoftware Maven JavaSwing
Sheetz
-
Architected and developed a standalone Electron application using React.js to interface with the GK Software API via two synchronized WebSocket connections. This tool provided store personnel with a dedicated dashboard for real-time status monitoring, transaction logging, and alert management for self-checkout RAP stations, directly enhancing support efficiency for Sheetz stores.

Side Projects
Tamagotchi Clone
2025
Developed a Tamagotchi-style virtual pet game on an ESP32 microcontroller, programmed in C++ (Arduino framework).
Drove a monochrome OLED display via the I2C protocol to render custom pet animations, status screens, and a real-time UI.
Engineered the game logic to manage a state-based pet needs system (hunger, happiness, energy) requiring user interaction.
Implemented input via physical buttons and managed system resources to run the game loop efficiently without an OS
ESP32 C++
ProtoCoop Stereo Pedal Switcher
2022
Designed and programmed a custom 8-loop stereo effects pedal switcher from the ground up using an ESP32 microcontroller.
Developed embedded firmware in C++ to manage real-time audio routing, switch analog solid-state relays, and implement a SD card subsystem to save/load all machine configurations.
Engineered the PCB layout to support true parallel input routing, a dedicated headphone output with its own amp, and minimal noise for studio-grade signal integrity.
Built and tested a fully functional unit, taking it from initial concept to a finished product in a custom enclosure.
Arduino ESP32 C++ Fusion 360
Game Development
2021
Several game in various stages of development. Made in Unity.
MCGHA (Midi Controlled Glass Harp Array)
2021
Robotic array of 6 wine glasses with variable functional mass controlled by midi keyboard input. Allows up to 6 voices simultaneously, more than the traditional glass harp. Additionally capable of portamento, staccato and legato, and laissez vibrer.
