“𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝗘𝘅𝗽𝗹𝗼𝗿𝗲𝗿” 𝗽𝗿𝗼𝗷𝗲𝗰𝘁: an interactive tool for visualizing the carbon emissions of the entire European building stock, while presenting different carbon reduction strategies. Carbon emissions can be visualized according to the stages of the building life cycle, building types, etc. This is the interface of the study titled "Support Study for the Development of the Roadmap for the Reduction of Whole Life Carbon of Buildings," funded by the European Union. 𝗔𝗰𝗰𝗼𝗺𝗽𝗹𝗶𝘀𝗵𝗲𝗱 𝘁𝗮𝘀𝗸𝘀 : - Built everything from backend to frontend - Developed a REST API to read and serve data from Parquet files - Visualized the data with Recharts - Tested my code with Vitest and Playwright - Worked with container-based CI/CD - Wrote documentation for users and developers - I collaborated with the UX/UI designer and the data team

“𝗣𝗹𝗮𝘁𝗲𝗳𝗼𝗿𝗺” 𝗽𝗿𝗼𝗷𝗲𝗰𝘁: event management and candidate follow up website. Several “child” applications derived from a “mother” application have been created in order to satisfy different customer needs (Réalise Tes Rêves, Marseille Capital de la mer, FFTDA and many others!) 𝗔𝗰𝗰𝗼𝗺𝗽𝗹𝗶𝘀𝗵𝗲𝗱 𝘁𝗮𝘀𝗸𝘀: - creation of an internal library - maintain the design system - wrote documentation (for users and developers) with Docusaurus - implemented a WebSocket - CI/CD manager - Proposed and implemented: → end-to-end tests with Playwright, reducing the bug rate per release by 40% → a GitLab pipeline that cut the total time from bug fix to production deployment by 30%
