Short description (2–3 sentences)

Built a full-stack Personal Fitness Tracker where members log workouts, meals, and water; set goals; join challenges; and interact with trainers through Q&A and feedback. The app uses a PHP REST API with MySQL, a Next.js 16 member frontend (static export), and a PHP admin CMS. Includes Stripe/PayPal membership payments, role-based access (admin/trainer/user), OpenAPI documentation, and Playwright E2E tests.
