  • Local Heroes

    A web application that is a directory of local producers, farmers, and small businesses in Switzerland, to help promote them during the pandemic. The app was very popular in Switzerland during the spring of 2020, especially in the francophone region.

    Implemented almost all of the front end and back end. Used React for the front end and Firebase Realtime Database and Firebase Functions for the back end and authentication.

  • Ad Campaign Management

    Developed a web application that was the flagship product of an advertisement data and analytics company.

    Handling large amounts of data, I contributed to the implementation of an interactive dashboard and allowed users to export reports in different file formats.

  • Customer Service Management Platform

    A web application used by the company to manage support tickets, and another one used by the company's customers to track the service received and technician appointments.

    I developed new functionality for both applications in the project. Added a rating system and a real-time map with an assigned technician's location and their estimated arrival time.
