Overview
What this project is
This project is a reservation management system designed to support restaurant booking workflows through structured data, CRUD operations, and role-oriented user flows. It focuses on practical operations rather than purely presentational UI.
Problem
Why this project exists
Reservation workflows become difficult to manage when booking details, table states, and service coordination are handled inconsistently. The project was built to create a clearer operational system for managing reservations and seating flow.
Goals
Project goals
- • Build a full-stack application for reservation and seating workflows
- • Support CRUD operations with validation and operational rules
- • Model practical restaurant coordination needs in the database and UI
- • Create a clean, responsive interface for day-to-day workflow management
System
System architecture
The application separates frontend workflow views, backend business logic, and relational data storage so reservation handling remains structured and easier to maintain.

- • Structured backend logic for stateful reservation handling
Technical Decisions
Important implementation choices
Why PostgreSQL
Reservations and table states require structured relationships and reliable querying, which made PostgreSQL a practical choice for the application data model.
Why Express for backend logic
Express provided a straightforward way to handle reservation workflows, validation rules, and API endpoints without adding unnecessary abstraction.
Why prioritize workflow over decoration
For operations-heavy applications, clear interaction flows and state handling matter more than purely aesthetic interface choices, so the project prioritized usability and task completion.
Constraints
Challenges and limitations
Reservation systems have many small operational rules that can create bugs if not handled intentionally. A key challenge was translating real workflow constraints into backend validation and predictable UI behavior.
Outcome
What this project demonstrates
This project demonstrates full-stack application design, database-backed workflow management, and the ability to model practical operational systems with clear user-facing interactions.
Next Steps
Future improvements
- • Refine table management and edge-case handling
- • Improve interface clarity for high-volume service flow
- • Add stronger reporting around reservation activity
- • Modernize the rebuild with updated styling and documentation
