Toptal React Academy | Restaurant Reservations Management System

This project was developed as the graduation project for the Toptal React Academy which is an exclusive learning program that teaches the React framework to select members of the Toptal network. After a month of study, all graduates are tasked with completing a 30-40 hour final project to build and deliver a React app from scratch. The above is a walkthrough of my final project.

A table reservation system for restaurants. The web application is built to help restaurant managers track the reservations they receive by phone or email.

After successful registration, the manager starts by setting the restaurant name and adding a layout for the available tables and the number of seats per table. Reservations can then be added and managed for each table, and reports are generated per day and table.

Kiosk Client Application for Microsoft Lync

https://www.youtube.com/watch?v=i3NRRSkQ62g
This system is developed as an alternative Lync terminal in a kiosk with touch screen enabled interactions. It should work as an agent to enable the communication between guests and company employees wherever they are.

It is designed to provide new ways of customer service through video conferencing access to expert advisors and agents within the contact center or enterprise through any touch device.

Live Coverage App for the Egyptian Presidential Elections 2012

Developed a web application to provide live coverage for the Egyptian presidential elections 2012. The election results were announced at the polling locations (around 15,000 locations around Egypt), and then they were aggregated to reach the total result.

The idea was based on crowdsourcing principles where anyone can send the final result to a nearby location. Then all results are reviewed and aggregated directly to update and display the results in real time.

The application went viral during the election days, and it got around five million unique views in the first 24 hours. It was also featured and praised on multiple TV and online media channels covering the sorting process for being accurate and unbiased.
