Based in Pensacola, Florida.
Studying computer science at the University of West Florida, graduating May 2028.
I co-founded the UWF Brazilian Jiu-Jitsu Club and grew it to 30+ members, then built the software it runs on.
I work mostly on backends and data: Python, FastAPI, PostgreSQL.

Projects

BJJ Check-In System

Python · FastAPI · PostgreSQL · Jinja2 · Railway

QR-based attendance system for the UWF Brazilian Jiu-Jitsu Club, a 30+ member organization. Replaced a paper sign-in sheet and is used at the door every session.

  • Members check in from a phone at the door. Admins get a dashboard instead of a spreadsheet.
  • Retention view tracks where members came from and flags anyone inactive for 21+ days.
  • Postgres upserts and unique constraints prevent duplicate records when several people check in at once.
  • Raw SQL over psycopg3, no ORM. Deployed on Railway with bcrypt-hashed admin auth and signed session cookies.

Patient Management System

C++ · STL

Command-line application to store, search, update, and validate patient records.

  • Record creation, lookup, and updates with input validation on every field.
  • Classes and vectors to organize patient data and the operations on it.
  • Error handling built so a bad input never corrupts an existing record.
