Evolution: The Video Game

Evolution: The Video Game is a digital adaptation of the board game—Evolution.

I led a team of developers in bringing the board game to life in the video game format. I also created all of the application's architecture and integrated it with multiple departments.

The game was built in Unity3D and deployed to Steam, iOS, and Android. The back end was built using PlayFab BaaS and Photon.


I am part of a speed-running community for a ROM-hacked version of The Legend of Zelda: A Link to the Past, which randomizes the game.

Per legal requirements, there is a website where seeds are generated for the players. For my Discord community, I built a Discord and Twitch bot—along with a small team—to assist with generating seeds on the website and managing races within the community.

It used a Node.js back end utilizing Discord.js and tmi.js to interact with both services while controlling the races. The data was stored in a MySQL database.

Measure! Everything!
A mobile AR app that encourages kids to explore the world around them and measure objects using the AR camera. The intent is that kids will become more comfortable with math from an early age if they are exposed to it through fun experiences. Worked on the back-end system, utilizing PlayFab to handle parent accounts, child player profiles, and content management.

Custom 3D Model Storefront PoC [NDA]

A client that made 3D printed models wanted to expand his website to include the ability to make customized models and either put in the order to download the files to print on your own 3D printer or to have the company print and ship for you.
I built the front end using Unity WebGL, and the back end was built using Node.js and MongoDB.

ESTA Visa Waiver Website
I worked on modernizing the DHS CBP ESTA Visa Waiver application website, allowing people visiting from outside the U.S. to apply for a visa waiver to travel into the U.S. This was an online form written in HTML, CSS, JavaScript, and Bootstrap.

Employee Training Application [NDA]

An internal client needed a portion of their website where employees had to complete required training classes to meet the regulatory standards.
I built the website in AngularJS with a Node.js back end hosted on AWS.

Real-time Networked Multiplayer Educational VR Experience [NDA]

Students can connect instantly to a VR classroom in which a teacher and other students interact with an immersive lesson plan, set in a location that wouldn't be feasible to visit in the real world.

Each participant has access to real-time, 3D spatial voice chat, allowing for natural communication, in addition to fully networked interactions within the virtual space such as pointing, waving, and manipulating objects. A narrated audio track helps inform students as they move through the lesson, providing educational content in addition to that provided by networked instructors.

Nintendo Switch Port [NDA]

A studio had contracted an industry friend to work on a Nintendo Switch Port of their game and the Switch side of the cross-play multiplayer system.
I helped with debugging the Switch build, optimizing the code, and working on multiplayer.


The client wanted a number of public service announcement experiences that were built in VR. They show a number of scenes where the player can interact in the VR environment and see the outcome of their actions. All of these experience showcase students in real-life situations and plays out this situation to a specific point. Once the situation reaches a tipping point, the player is asked whether they should intervene in the situation or allow the situation to play out. What then unfolds is the consequences of either doing the right thing or letting the other characters make their bad choices. It utilizes Unity and VRTK to generate these experiences.

Driving App [NDA]

This app was built to help student drivers log their hours while practicing to take their driver's test. The mobile application worked for both iOS and Android and was connected to an AWS back end written in PHP.


PlantManager, which was called VCEPlantManager when I worked on it, is a four-tier C# application that models all of the equipment within a refinery and runs complex calculations for reliability and inspection data for when shutdowns occur.

Pier Pressure

Pier Pressure is a multi-part app featuring a role-playing game true to the “US Navy experience.”

Players go through the life of a naval officer working through the ranks of the US Navy while still having fun at night with their friends. The game is coupled with resources to help sailors practice responsible drinking behavior in real life.
