Quicktab

Contactless dining at your fingertips. Quicktab creates a digital way for restaurant guests to view the menu and order food all from their phone.

See My Contributions

As part of the requirements in completing my post-graduate program studies at George Brown College, I worked as an iOS Developer Intern at Dyne Techologies, Inc. and was able to work on and provide contributions to the company’s flagship iOS app called Quicktab. 

App Landing Page Creation

Implemented the Landing Page screen for the app that will allow users to browse through different restaurants supported by Quicktab and view the restaurant details (photo image, address, opening hours, menu, ratings, etc.). Highlights for this feature include the following:

Consumption of Google Places REST APIs to allow display of restaurant information such as address, opening hours, ratings, photo images and reviews.Implementation of Apple Core Location services for location-based restaurant check-in and display of nearby restaurants.Implementation of services provided by MapKit to show selected restaurant location map.Implementation of access to Firebase’s Firestore database to retrieve additional information from the restaurant that is not provided by the Google Places API. 

Code Refactoring

Refactored the Navigation Menu and Log-in screens of the Quicktab app so that constraint-based layout of user-interface objects will be implemented programmatically instead of using Storyboards.

Custom View Development

Created custom views to be used in different view controllers within the Quicktab app such as custom swipe buttons and custom user-input views.

App Improvements

Added dining party invite functionality within the application’s Welcome screen.Implemented location-based check-in function that will allow a user to join a dining session only when the user is in within the restaurant’s vicinity.Implemented improvements in existing application features which include feature changes in the Menu, Order and Billing screens as well as utilities used for dining session transactions.

App Debugging and Testing

Participated in the testing and debugging prior to Quicktab app releases as well as implementation of UI and feature improvements for the app based on user feedback. Significant debugging contribution include fixes to QR code-based restaurant check-in function as well as bug fixes to UI layout issues found within the Menu, Order and Bill payment screens.
