System Architect

A queuing system for government service offices. It keeps issuing tickets with the network down, and it records how long every customer actually waited.

Overview

Government offices run on physical queues, and nobody measures them. NextQue digitizes the flow. Tickets, window calling, and wait-time records, sized for the hardware these offices already own.

Architecture

A Java desktop app built in Apache NetBeans with SQLite as the embedded store. The hard requirement was offline operation, and SQLite makes it absolute. I led the design across three versions, from a single-window prototype to a multi-window layout with a public display screen for called numbers.

Outcomes

Ticket flow that keeps working offline
Wait-time data for every ticket
Three versions shipped from user feedback
Deploys as one JAR and one database file
