Back-end/Mobile developer

Project Overview

A thrilling project designed to elevate the corporate experience for the company's dedicated employees. The game was divided into distinct zones, each offering a unique set of questions and challenges. As participants progressed through the app, they unlocked new zones based on their achievements and the time elapsed. This dynamic system ensured that every moment was packed with excitement and anticipation. To make this adventure possible, the team leveraged cutting-edge technology. Firebase served as the secure repository for the app's data, ensuring seamless data storage and retrieval. The app itself was built using Flutter Web, providing a user-friendly and responsive interface that could be enjoyed across various devices. Behind the scenes, a Node.js server facilitated communication between the app and the game's infrastructure, ensuring smooth gameplay and real-time updates. Additionally, the team harnessed the power of Firebase Cloud Messaging (FCM) to deliver push notifications, keeping participants engaged and informed throughout their adventure. These notifications added an extra layer of excitement by alerting players to new challenges, time constraints, and achievements.
