# Create first US: ## using React, Material UI, Sass 1. Create a perfect pixel dashboard layout for checkers and analyst(it just contains a card that have the assigned jobs). 2. Implement API call for get assigned jobs. - Configure MSAL(Microsoft Authentication Library for React). - Use @react/msal library and auto-login using AAD(Azure Active Directory), then get the Token. - Call API using Axios and throw a token since all APIS are secured. - Refactor the code and use a generic components and custom hooks. # Work on RIDOT(Rhode Island Departement Of Transportation) project ## MOA: Bussiness Analyse 1. Help the client to refine their requirement and have a data tree, and use case diagram and all the design steps. 2. needs analysis. 3. Prepare a macro estimate in terms of time and effort for the entire build 4. Work on the authentication part: - Creation of UI (MUI, scss, JSX). - Creation of authentication mock while waiting for the API (zustand). - Consumption of the authentication API (React-query). - Implementation of interceptors to bind the Token to each request header (pour axios). - Refactor code and make reusable components. 5. Work on scheduling configuration: - Create a Button to add new configuration and an infos message in case of the state of the project is `NEW`. - Create a form to create and update configurations. - Create scheduling details page.

CRI4DATA : Création du plateforme DP4CC pour une Société d'assurance Française, j'intègre un groupe de deux développeurs sous la responsabilité directe de CTO (Expert informatiques et Assurance) # Front-end: - Vue: Création des `reusable components`, les standardiser pour l'utiliser dans plusieurs partie de la plateforme. - VUETIFY: pour ajouter les elements necessaire pour un VUE (Design + API). - WEBPACK: Préparer les fichiers Javascript pour l'utiliser ensuite par le navigateur en faisant le bundle que ce soit en mode developpement et production. - I18n: Internationalisation en ajoutant des differentes Langue pour la plateforme. - MDI: Utiliser des icons de material design. - DEBUGGAGE: avec Chrome DevTools. # Passerelle: - Utiliser Nginx comme passerelle. # Back-End: - Node: Utiliser node js pour notre serveur. - REST/API: Utiliser l'architecture REST pour créer les differentes services. - MoleculerJs: utiliser moleculer JS comme framework pour le serveur. - PKG: Utiliser le bundling niveau serveur en créant un fichier binaire pour protéger notre code source et avoir une version minimale qui marche sans node. - DEBUGGAGE. # Documenter le code dans README.md # Oracle VM VBox: - Creation des machines virtuelles ubuntu pour tourner le serveur en environnement de developpement et production. - Création des script shell pour automatiser les installation, le bundle et meme le lancement de certaines services. # End-2-End Testing: - Utiliser Cypress pour les testes e2e. # Outils: - Utiliser File zilla pour envoyer les fichiers de poste de travail vers la machine virtuel a l'aide du SSH afin de lancer le serveur avec les nouvelles fonctionnalitées développer. - Utiliser Git pour le système de versionnage a l'aide de sourceTree comme GUI. # Agile / Scrum: - Utiliser Tuleap pour manager le backlog. - Avoir Clean code et appliquer les bons pratiques lors de création de code.
