ℹ️ Certified Innovation Tax Credit (CII) and Research Tax Credit (CIR): recover 20% of my invoices as tax credits.

Hello! I'm Clément, an experienced iOS & web architect since 2008 (yes, back when iOS was still called "iPhone OS" 😉).

Your idea deserves to be challenged, refined, and brought to life quickly: that's exactly what I do. I design and develop performant web & mobile MVPs in one to two months, so you can test, pivot, and quickly launch your product on the market.

🎯 𝗪𝗵𝘆 𝗰𝗵𝗼𝗼𝘀𝗲 𝗺𝗲?
• 𝗘𝗻𝘁𝗿𝗲𝗽𝗿𝗲𝗻𝗲𝘂𝗿𝗶𝗮𝗹 𝗘𝘅𝗽𝗲𝗿𝘁𝗶𝘀𝗲: Founder of several startups such as Tickt (sold), Les Tontons Livreurs, Just A Call, Callsomer (sold), and other consumer apps, I understand your business challenges, not just the technical ones.

• 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗘𝘅𝗰𝗲𝗹𝗹𝗲𝗻𝗰𝗲: Specialist in iOS/macOS development (organizer of Cocoaheads Lille) and international speaker at AltConf San Francisco, React Europe Paris, Twilio Signal London, iOS Conf Singapore, and SwiftConf Cologne.

• 𝗣𝗮𝘀𝘀𝗶𝗼𝗻 𝗳𝗼𝗿 𝘁𝗲𝗮𝗰𝗵𝗶𝗻𝗴 𝗮𝗻𝗱 𝗺𝗮𝗸𝗶𝗻𝗴 𝘁𝗵𝗶𝗻𝗴𝘀 𝗰𝗹𝗲𝗮𝗿: I have taught at Supinfo, MediaSchool, IB/Cegos, Hexagone, and given a series of lectures at Harvard.

✨ What my clients appreciate most: My attention to detail, my pragmatism, and above all my ability to offer you creative and concrete solutions that boost your business through digital innovation.

🗣️ Let's talk about your project together and bring your idea to life today!


Regarding my daily rate, thanks to the 𝗜𝗻𝗻𝗼𝘃𝗮𝘁𝗶𝗼𝗻 𝗧𝗮𝘅 𝗖𝗿𝗲𝗱𝗶𝘁 (𝗖𝗜𝗜), my workday costs you €600 excluding tax after tax deduction (if applicable, otherwise we can discuss).

See you soon,
Clément

    Kenkois a new generationhealth insurance mobile applicationthat allows its users to manage their reimbursements, health procedures, and included wellness services, all within a fluid and 100% digital experience.

    I supported Kenko in the complete redesign of their application following their €4 million funding round, with the goal of elevating the product to a premium standard, both ergonomic, modern, and scalable.

    Mission

    • Real-time reimbursement tracking

    • Direct access to the Third-Party Payment card
    • Management of health guarantees and hospitalizations
    • Access to partner wellness services (Happypal, Mindday, teleconsultation, etc.)
    • Support product and technical teams in implementing a coherent and scalable design system

    Results
    • A redesigned, fluid, and engaging user experience
    • A stronger visual identity, consistent with the post-funding positioning

We have only just begun the project study, but he has presented a very complete and accessible report to all departments. They have captured the essence of a project that will be built from scratch very well and have contributed many ideas. We are confident that it was a good choice to start a project with Clément.
