Unnanounced VR Football Project

An immersive gaming experience for fans that allows them to be as close to the game as they have ever been while at the stadium or in the comfort of their own home.

As the lead developer on this project, I've implemented the game architecture and core mechanics, built out the UI, and developed the multiplayer systems. Additionally, I have profiled and optimized code for performance and built editor tools for faster iterations on the project.

Pre-game Prep App

Pre-game prep is a desktop application designed for professional football coaches, allowing them to create and edit plays and then simulate them in 3D.

As the lead AR and VR developer on this project, I developed a VR application that allows to visualize the custom-drawn plays and connect multiple clients to a networked session with the desktop application.

HBR AR Experience

The HBR Augmented Reality app launches an interactive AR experience from the pages of Harvard Business Review that explores the key AR use cases presented in the article — visualization, instruct and guide, and interact.

As the lead developer, I implemented the application architecture, flow, and core features, built out and animated the UI, and integrated game assets. The project was later ported from mobile to HoloLens.

Kulipari: Dream Walker — XR POC

This project is a short demo of gesture-based mechanics in a fantasy world. Developed with HTC Vive but destined for a mixed reality headset platform. As the lead developer, I designed the flow, implemented the mechanics, and integrated the particle effects.

Mercedes AMG — Mixed Reality Car Configurator

This project demonstrates how mixed reality can be used to configure a vehicle on a tabletop and visualize it in your driveway — plus an RC car version just for fun.

As the lead developer on this project, I implemented the application flow, integrated new assets, and optimized the app's performance. I also developed a minimal self-driving AI for the RC car version that uses HoloLens' spatial mapping functionality for environmental awareness.
