    Realization of a project from scratch in a team of four for 4 weeks using agile scrum methodology with one-week sprints. Sprint 0: Drafting the specifications, designing wireframes, user stories, logical data model, conceptual data model... Sprints 1: setting up our folder and file architecture with our React model and designing the skeleton of our mockup with static data. Sprint 2: integrating dynamic data and setting up Redux. Sprint 3 finalizing our MVP and fixing any bugs. Here is the link to our project (MVP version). The functional parts are registration, login, todolist, and family management. For the rest, it remains static information. It is hosted on free solutions, so response times can sometimes be a bit long (especially on the first API call, which is on a server that shuts down after a period of inactivity). https://family-deck.surge.sh/
