LA MESA

Android app to manage a restaurant end to end (check-in, table, order, kitchen and bar, games, survey and payment) with 7 profiles: owner, supervisor, maître d', waiter, cook, bartender and customer.

Team
4 members (Ezequiel Bainer, Maximiliano Arcieri, Noelia Storgato, Lucía Cicchelli)
My role
Coordination and development
Context
Final Integrative Project, UTN
Since
August 2026, weekly deliveries
Repository

It's an Android app: there is no web demo.

  • LA MESA start screen with the logo and the team members
  • New table form: number, seats, table type and a photo taken with the camera
  • New table created with its QR code for the customer to scan
  • Table management: list with photo, seats and status
  • Real-time question chat, waiter view
  • Games list with each discount and whether it was already played
  • Hangman in progress: right letters in green, wrong ones in red
  • Memory game in progress, with photos of dishes from the menu

Coordination

  • I created and managed the repository.
  • I defined the branching workflow: one branch per member, integration in dev and the stable version in main.
  • I integrated the team's work: 14 of 43 merges, the most on the team.
  • I kept the README up to date with progress, each member's modules, screenshots and the data model.

What I developed

  • Table creation and management: form with a camera photo, QR generation, validations and profile-restricted access.
  • Real-time customer–waiter chat and a waiter inbox with unanswered questions.
  • Validation that the scanned QR matches the assigned table.
  • Notifications for owner/supervisor, waiters and customers.
  • Discount games (hangman 10%, memory game 15%, trivia 20%), first attempt only: an attempts table and SQL functions that validate and calculate the discount, with unit tests.

Built by my teammates

Initial schema, authentication and RLS, employee onboarding, table assignment, login and sign-up, ID scanning, emails, survey, bill, menu, orders and kitchen/bar.

Stack

  • Ionic
  • Angular
  • TypeScript
  • Capacitor
  • ML Kit
  • Supabase (Postgres, RLS, Edge Functions)
  • Vitest

What I'd do differently

  • I'd add tests to more modules: today only the game logic has unit tests, and the order and payment flows need them too.
  • I'd plan from the start a way to show it without installing it, like a short video: since it's an Android app, it's hard to show in an interview.
