World 3 — Player Profile

The engineer behind the projects.

I'm a Computer Engineering graduate from Sacred Heart University with a Mathematics minor and production software experience at Sentari AI. I enjoy connecting the pieces of a system—from a clear interface to the data and hardware behind it.

Video games are part of how I build. My projects explore responsive controls, adaptive difficulty, and the connection between physical inputs and on-screen feedback. That interest also shows up in my full-scale pinball machine and custom arcade cabinet.

Experience & education.

Production work, a foundation in engineering, and a habit of learning by building.

Inside the work · Sentari AI

Making product activity visible to the team

The problem

The product team needed an admin view of referrals, retention, engagement, and user growth to understand activity on the platform.

My implementation

I built the analytics dashboard with Supabase RPCs and SQL, alongside React/Next.js features and backend APIs. The work connected interface, application logic, and database queries.

Team delivery

The dashboard brought these metrics into an admin interface for the team. I worked through pull requests, code reviews, and documentation with a 10+ member cross-functional team.
