Fitness Tracker App

Project 4

---

A full-stack fitness tracking app that combines calorie and food logging with workout tracking.

The backend is built with FastAPI and PostgreSQL, featuring JWT-based authentication, a TDEE insights engine using the Mifflin-St Jeor formula, and integration with the USDA FoodData Central API for nutritional data lookup. The frontend is built with React and Vite, deployed to Railway.

Future plans include GPT-4o Vision integration for food photo calorie estimation and gym machine recognition.
