An interactive Tic-Tac-Toe RL agent that improves in near real-time from human play.

A replicated, highly-available, and fault-tolerant chatroom server. Designed handle server failures and network partitions (full and partial). Implemented in Go using gRPC.

A 3D renderer built in C++ using raytracing on the CPU. Supports reflections and multiple light sources, and runs in real-time! (~30fps at 250x250 resolution).

Co-founded + led the technical development of VaccinatePA.org, a website for finding COVID-19 vaccine appointments in Pennsylvania. The site helped over 450,000 users find vaccines in PA, and had an amazing team of over 200 volunteer callers reaching out to vaccine providers across the state. You can view the news coverage and interviews here.

Trained a reinforcement learning agent in a simplified MOBA environment using self-play, LSTMs, Proximal Policy Optimization (PPO), Generalized Advantage Estimation (GAE), and Population-Based Training (PBT).

A 2D physics engine that can simulate the interactions of arbitrary convex polygons. Includes friction, bouncing, and fracturing!

A virtual fish tank with fish that evolve in real time to survive. They learn to search for food and avoid predators!

A 2D multiplayer arena-fighting game. It's integrated with an early version of my physics engine, and it features over-the-internet multiplayer and a server matchmaking system!

A little ant guy that uses his raytracing "antennae" to traverse random mazes! He learned to do this by evolving a neural network brain with my modular genetics library!

A 2D "Minecraft Clone" that features internet multiplayer, a day-night system, crafting mechanics, and caves!

One of the first games I ever made, and one of the greatest learning experiences. You're a farmer attempting to colonize an asteroid while fighting off waves of alien invaders!
