    SOFTWARE PUBLISHING
    May 2025 - Today (1 year and 1 month)
    Lille, France
    Beyond my assignments, I develop and maintain several projects independently, from product design to deployment.

    Notably, I designed PovEvent, a SaaS platform for collecting photos and videos for events (weddings, parties, seminars), developed from A to Z with Next.js, TypeScript, Supabase, and Stripe. This project covers all aspects of a real product: technical architecture, UX, payment management, and business constraints.

    I also assist a client in developing a custom Chrome extension that allows their teams to automatically generate professional visuals in one click, using data from their website, ready to be published on their social media. This tool is designed to eliminate a high-volume repetitive task and save significant time for end-users.
