Tickety

A queue management system for Cameroon, with a REST API, web app, and Android app, built around phone-first login.

Summary

Tickety is a digital queue and ticketing system designed for the Cameroonian context. Service providers manage queues with counters, priority rules, and scheduled opening and closing times; users take tickets from the web or from the Android app. Because phone numbers are more widely used than email in Cameroon, users can sign in with either a phone number or an email address via a one-time code (OTP).

Role

Full-stack developer across the backend, web client, and mobile client; the Flutter mobile app is developed with a collaborator.

Android app

APK download available from the landing page.

  • Multiple service counters
  • Priority handling within queues

Architecture

  • Backend: Flask REST API using SQLAlchemy, served by gunicorn on a VPS. MySQL in production, SQLite for local testing.
  • Web client: React.
  • Mobile client: Flutter (Android).
  • CI/CD: GitHub Actions workflows run the test suites and block deployment if tests fail.
Tickety architecture: React web client and Flutter Android app call a Flask REST API served by gunicorn, backed by MySQL in production and SQLite in local testing, with GitHub Actions gating deployment. Web client React · Vitest GitHub Actions tests gate deployment Android app Flutter · Dart Flask REST API SQLAlchemy · gunicorn · VPS OTP delivery email · Brevo SMS MySQL production SQLite local testing HTTPS / REST HTTPS / REST deploy on green build
Both clients talk to the same Flask REST API. One-time codes are delivered by email or Brevo SMS, and GitHub Actions blocks deployment when the test suites fail.
