Game Center Billing & POS

A custom billing and point-of-sale application created for a game center to manage gaming sessions, customer billing, snack sales, inventory, expenses and daily operations from one system.

The platform provided separate access for administrators and managers while replacing disconnected manual records with a centralized operational workflow.

I handled the full-stack development of the application, including backend APIs, frontend integration, database design, authentication and business workflows.

My responsibilities included:

Designing the application architecture and database structure

Developing REST APIs using Node.js and Express

Building operational interfaces using React

Implementing JWT authentication and role-based access

Creating gaming-session and time-based billing workflows

Developing product, snack-sale and inventory management

Implementing expense tracking and daily closing

Building billing summaries, receipts and operational reports

Testing application workflows and resolving issues

The system allowed staff to start and manage PC or console sessions, calculate usage charges and combine gaming fees with food or product purchases in a single bill.

Administrative features provided visibility into daily revenue, expenses, inventory, employee access and completed transactions. Role-based permissions restricted sensitive management functions to authorized users.

Centralized gaming-session and POS operations

Reduced dependency on manual billing records

Improved visibility into daily revenue and expenses

Simplified inventory and snack-sale tracking

Provided secure access for administrators and managers

Created a foundation for consistent reports and daily closing
