Conception et intégration d’une plateforme d’apprentissage basée sur Open edX pour 2600, école de cybersécurité. Objectif : permettre à des élèves d’avancer en autonomie partielle pendant une séance en classe, avec un professeur capable de suivre la progression, repérer les blocages et intervenir au bon moment. Environnement : Open edX, Tutor, Docker, Django, React/MFE, Keycloak, OIDC, GAR, GitLab, Linear, Proxmox. Highlights : - Cadrage produit : rôles apprenant/professeur/pédagogie, parcours utilisateurs, organisation des cours, suivi en classe et priorisation MVP. - Prise en main rapide d’Open edX : LMS, Studio, Tutor, MFE React, thèmes, traductions, XBlocks/JSInput, Aspects/Superset, Discovery, rôles et inscriptions. - Mise en place et debug d’environnements locaux et serveur : Docker, VM Proxmox, SSH, VPN, DNS, CORS, configuration Tutor, builds et déploiement. - Intégration de contenus et exercices cyber, avec travail sur le scoring, le tracking, la maintenabilité et le workflow Git pour les contributeurs pédagogiques. - Contribution à l’intégration GAR via Keycloak/OIDC : authentification institutionnelle, redirections login/logout, rôles élèves/professeurs et permissions Open edX. - Customisation produit/front-end : thème, traductions, MFE React, éléments de design et adaptation de l’interface au contexte de classe. - Usage intensif de ChatGPT, Codex et Claude Agent pour comprendre plus vite l’écosystème, explorer le code, prototyper, documenter et accélérer certains développements. - Documentation d’onboarding, conventions GitLab, merge requests, organisation des repositories, clarification du backlog Linear et accompagnement de nouveaux contributeurs. Mon rôle consiste à faire le lien entre besoin pédagogique, contraintes produit et réalité technique d’une plateforme Open edX en contexte institutionnel.

Mise en place du front d’une application NextJS/Django permettant aux utilisateurs de gérer leurs environnements de développement virtuels (Jetlab v3).

- Developed and published Incircle, a minimalist mobile game. (1.5 months) - Built and designed Helios Neopharma landing page. (1 month) (freelance) - Created SquadTS, a functional TypeScript rewrite of SquadJS using RXJS, tests, custom RCON (TCP/IP) client, and FTP-based log file parsing. (1.5 months) - Built Labyrinth prototype, a Unity-based mobile asymmetric co-op game. (2 months) - Continued development of Mandala Vibratoire, a visual web app built with React and GLSL. (2.5 months) - Prototyped several Unity games (mobile and desktop), including sprite-cutting mechanics, a solo shape-based game, and an unfinished React Native app. (5.5 months) Tech: TypeScript, React, NodeJS, Unity, GLSL, SQLite, Electron, React Native, RXJS, Docker, docker-compose, Tauri, Nginx, Playwright, Supabase

- Implemented features from detailed specifications (tickets). - Created a one-click tool to update Atlas Search indexes across environments. - Refactored CI pipelines (~1300 lines). - Consolidated ~15k lines of TypeScript from 3 Loopback services into a reusable library. - Wrote and restructured internal documentation for onboarding. **Tech**: NodeJS, TypeScript, Loopback, Angular, MongoDB, AWS, GitLab

- Built frontend (7.5 months) and backend (2 months) of **Mandala Vibratoire**, a visual tool to create mandalas based on sacred geometry. - Developed a second-brain knowledge management desktop app using React, Electron, and SQLite (6 months). - Delivered custom JavaScript lessons and tutoring (~2 months), including course platform using Docusaurus. **Tech**: TypeScript, React, NodeJS, Electron, SQLite, GLSL, Docker, Docusaurus

- Built and maintained 4 key React-based services (DataSquare, DataAdvisor, Blog, Design System) within the “DataSquare” platform, designed to promote the use of data across SAFRAN (1,500 users and 4,700 page views in late 2019). - Mentored 4 developers (intermediate to senior) on frontend development, including React, TypeScript, UI/UX, and project structure. - Integrated Storybook to support a new design system led by the UI/UX designer; maintained the internal NPM package and CI pipeline. - Authored and organized documentation on CI/CD, Gatsby, onboarding, and internal tools (Firefox, SAP). - Championed adoption of Slack, WebStorm, Git conventions, and tooling that improved team productivity. - Led prototyping and strongly influenced final choices for core tech stack: - **Gatsby**: selected over Hugo/Jekyll/WordPress for combining React component reuse, UI customization, and static-site performance - **Strapi**: proposed as a headless CMS for locally-hosted backend CRUD, custom frontend flexibility, MongoDB support, and content manager usability - **NodeJS**: advocated over Python to simplify tooling and align with frontend stack - **Storybook**: chosen for UI component development over Styleguidist - **Cypress** (later replaced with Puppeteer) for end-to-end testing, adapted due to firewall constraints - Supported team members in testing, component decomposition, debugging, and advanced Git usage (rebase, squash, cherry-pick). - Participated in hiring, code reviews, SCRUM rituals, and long-term technical planning. - Recognized by UI/UX designer for precision and user-centric implementation. **Tech** : React, Gatsby, Storybook, Puppeteer (alternative à Cypress), Jest, GitLabCI, Docker, Portainer, Nginx, NodeJS, Strapi, MongoDB, SCRUM, CSS, SCSS, HTML
