Software, data & useful ideas.

Mareano.

My work brings together research, data, design, and software development. I’m interested in the whole process, from understanding what’s needed to figuring out how the pieces should work together.

Sports research, open to everyone.

Vantic brings team and athlete statistics, sources, and analysis into one place. I’m building it to make sports research easier to explore, with both web and native app experiences.

A connected view of a moving city.

Harrisonburg OS connects public geography, road-volume records, and population estimates in an interactive city model, with a clear distinction between observed data and simulated movement.

Internal BI, from discovery to dashboard.

I built Greyline during my SuccessKPI internship to connect requirements from discovery and demo conversations with demo preparation, KPI calculations, and dashboard creation and presentation. I handed off the application and supporting materials for further development and implementation.

Computer vision & interactive play

Independent projects

I’m exploring how live camera input can make software respond to the way people move. I built these games and their environments around Google MediaPipe’s hand and pose tracking.

Pinch & Play

Completed

Pinch your thumb and index finger together to make the character jump over obstacles. A small camera-controlled game with keyboard and touch options, too.

Demo video coming soon

Cup Pong

In development

A cup-toss game controlled by your throwing motion. Arm tracking turns movement in front of a MacBook camera into an on-screen shot.

Curious about the problem.
Hands-on with the solution.

I’m a Computer Information Systems student at James Madison University. I like working through an unfamiliar problem, finding the information that matters, and building something useful with it.

My experience spans software development, analytics, public-sector technology, and solutions consulting. AI lets me take on more of a product myself, from data workflows and coding to interface design and testing. I use tools such as Claude Code and Codex while owning the technical decisions, understanding and explaining how the system works, and validating the result.
