About Kevin

I help startups go from idea to production mobile app. Dart since 2013, Flutter since its inception, and 5 years as a Google Developer Expert.

My track record: a FinTech app managing digital assets (Regular), a cross-platform BLE package still used 5 years later (Dooz), and +15 consulting missions delivered. From intensive workshops (Boursorama, ADEO) to multi-month CTO partnerships (weebi.com).

What I deliver concretely:
→ Mobile architecture designed to scale from day 1
→ MVP or takeover of existing apps
→ Training your teams to make them autonomous
→ Dart or Go backend when the project requires it

Based in Toulouse, I work remotely with startups and scale-ups in France and internationally.

    January 2017 - Today (9 years and 5 months)
    Toulouse, France
    I help startups and scale-ups ship mobile products with Flutter and Dart — from first commit to App Store.

    As an independent consultant, I embed directly with founding teams to own the technical side: architecture, development, hiring support, and developer training. My engagements range from 3-day intensive workshops to 11-month CTO-level partnerships.

    Selected missions:

    ▸ NoCoffee / Dooz Smart Home (22 months) — Built a custom cross-platform BLE (Bluetooth 5) package from scratch. Abstracted iOS CoreBluetooth and Android BLE SDKs into a single Dart API used by the entire smart home app. Still actively used and maintained by the community (42 GitHub stars).
    ▸ weebi.com (11 months) — Fractional CTO. Owned full stack from Dart gRPC backend to Flutter mobile app. Managed technical strategy and delivery.
    ▸ XOXNO (8 months) — Led Flutter development for a blockchain marketplace. Standardized reusable Dart packages for API and service integration.
    ▸ MUNIC (6 months) — Embedded to elevate app quality: implemented best practices, authored technical documentation, improved test coverage.
    ▸ Lunii (3 months) — Senior dev reinforcement to unblock critical path and accelerate product launch.
    ▸ ADEO Services (3 months) — Built Flutter architecture from scratch, trained ~5 developers, created white-label components for the ADEO app ecosystem.
    ▸ Boursorama (3-day intensive) — Designed and delivered a hands-on Flutter training workshop for their mobile engineering team.

    Also building open-source tools:
    • spark.kleak.dev — Web framework for Dart backends, used in production
    • xfwd.link — Link shortener service, built and deployed solo
