COACH GYM — A Complete Gym Management Solution

COACH GYM is a full-stack web application designed to simplify and modernize gym operations through one centralized management platform.

The system brings together essential business operations, including:

Member Management: Registration, profiles, memberships, renewals, and attendance-related workflows.

Payments & Finance: Payment tracking, outstanding balances, partial payments, and transaction records.

Staff & Permissions: Role-based access control for owners, administrators, employees, and coaches.

Scheduling & Bookings: Organized management of appointments, classes, and related activities.

Security & Reliability: Authentication, audit logs, access restrictions, and software testing.

My Role

I led the project's planning and development process, defined business requirements and workflows, coordinated technical implementation, and performed hands-on testing to verify critical operations.

Technology Stack

Next.js, React, TypeScript, NestJS, PostgreSQL, Prisma, and automated testing tools.

Project Status

The application has been developed and tested locally, with production deployment and operational rollout planned separately.

About the Video

The attached promotional video introduces COACH GYM and demonstrates the product's visual identity and user experience.

The project reflects my experience in software development, system architecture, problem-solving, quality assurance, and building practical technology solutions for real business needs.

For class bookings, the edge case I’d test first is two people checking out for the last spot at once. A short reservation hold plus an atomic capacity check can prevent overselling; how are you handling concurrent bookings?
