About Guillaume

I design and develop complete web and mobile applications — design, development, deployment, and monitoring — so you can entrust your entire project to a single partner and stay focused on your business.

What I deliver:
  • Custom web applications and sites: showcase sites, SaaS, dashboards, and back-offices (Next.js, React, TypeScript)
  • iOS and Android mobile applications with a native experience: push notifications, app store publishing, management back-office (React Native, Expo)
  • Robust backends, ready to scale: APIs, business logic, databases (Python, Django, DRF, PostgreSQL)
  • Deployment and automation: your product goes live — and stays live (Docker, CI/CD, AWS, Vercel)

My background in two lines: for almost 3 years, I worked on the backend of Sketchfab, a 3D platform used by millions of creators, then contributed at Epic Games to building FAB, its asset marketplace. In 2024, I founded Fusily, a mobile recipe and meal planning app that I designed, developed, and published alone, from the first screen to the app stores.

My working method: clear scope definition, mockups before code, iterative development with regular check-ins, and clean, tested, and documented code that you fully own — no dependencies, no vendor lock-in.

    Fusily is a mobile application (iOS and Android) that simplifies recipe creation and sharing, as well as meal planning, while reducing food waste.
    I designed, developed, and published the product end-to-end, alone:
    • React Native / Expo mobile application, published on the App Store and Google Play
    • Django / DRF backend with PostgreSQL database: user accounts, recipes, meal planning, shopping lists
    • Delivery pipeline: EAS builds, OTA updates, versioning strategy aligned with native runtimes
    • Brand identity and interface design, multilingual screenshots for the stores
    • Content and marketing: website, social media (Reels), content production automation
    Fusily is also my live laboratory: every product, technical, and design decision is mine — it's the same level of care I bring to my clients' projects.
