Description

The Mechanics Schedule API is a comprehensive system designed to automate and manage vehicle maintenance appointments for a mechanic business. Developed with NestJS for the backend and Next.js for the frontend, the system not only handles the scheduling of maintenance services but also ensures optimal mechanic assignment, tracks maintenance tasks, and provides real-time updates to both mechanics and vehicle owners.

This project was created to solve the problem of scheduling conflicts, particularly the challenge of assigning multiple mechanics to different vehicles without overlap. Additionally, a module was developed for the mechanic to mark and track completed tasks on each vehicle. Using WebSockets for real-time communication and Push Notifications with Firebase, the system keeps everyone involved informed of the latest updates.

As the Lead Technical Developer for this project, I played a pivotal role in overseeing the technical execution, ensuring that all requirements set by the client were met within the project timeline. By applying the Scrum methodology, I was able to lead the team effectively and deliver high-quality results.

Technologies

• NestJS for backend API development
• Next.js for frontend development
• PostgreSQL (via Supabase) for data storage
• Firebase for Push Notifications
• Docker and Docker Compose for containerization and deployment
• Jest for backend testing
• ESLint and Prettier for code quality and linting
• WebSockets for real-time updates

Key Features

• Mechanic Assignment Management: Ensures that mechanics are never double-booked for the same time slot. The system assigns mechanics to specific vehicles based on their availability.
• Task Tracking: Allows mechanics to add and mark tasks as completed for each vehicle, ensuring an accurate maintenance history.
• Real-Time Scheduling: Utilizes WebSockets to provide real-time scheduling and updates, ensuring mechanics and customers are always up to date.
• Push Notifications: Integrated with Firebase for real-time push notifications, ensuring that mechanics and vehicle owners are notified about important events, such as task completion or new appointments.
• Vehicle Status Management: Manages vehicle status, preventing the scheduling of maintenance on vehicles not in an appropriate state (e.g., “in maintenance”).
• Frontend and Backend Integration: Developed with Next.js for a responsive frontend and NestJS for the backend API, offering a seamless experience across devices.
• Testing Suite: Integrated Jest for backend testing, ensuring the application remains reliable and of high quality.
• Containerization: The application is containerized using Docker and Docker Compose, simplifying development and deployment.
• Code Quality: Utilizes ESLint and Prettier for maintaining high-quality code standards and consistency.

Impact

This project significantly improved the efficiency and organization of vehicle maintenance scheduling in the mechanic business. By automating the assignment of mechanics to vehicles and tracking completed tasks, the business eliminated scheduling errors and optimized the workflow. Additionally, the use of WebSockets and Push Notifications improved communication between mechanics and vehicle owners, providing a more seamless experience. The system’s real-time capabilities, integrated notifications, and flexible scheduling have enhanced the business’s overall service quality and customer satisfaction.

Conclusion

The Mechanics Schedule API demonstrates the power of NestJS for building scalable backend systems and Next.js for delivering a fast, responsive frontend. With features like mechanic assignment management, real-time scheduling, task tracking, and notifications, this application addresses key challenges in the automotive service industry. It is deployed on Render for the backend and Vercel for the frontend, making it highly accessible and scalable. The project successfully met the requirements set by the client, thanks to the agile Scrum methodology, and has significantly improved scheduling flexibility and operational efficiency for the business. This application serves as a strong foundation for future expansions and enhancements.
