About David

Need to launch a Web MVP at record speed or boost your mobile app without compromising on quality?

Senior developer with 15 years of experience, I combine the power of AI-assisted development (Vibe Coding mastered via Claude Code) and the rigor of an architect to design robust, scalable, and bug-free products.
Previously in key positions (Senior & Lead) on high-audience applications (Mappy, Voodoo, WeMoms), I bring exceptional execution speed for Web and absolute engineering excellence for Mobile.

My stance on traditional "Vibe Coding": I do not use AI to generate code blindly. My role is to optimize Claude through advanced prompting and sophisticated techniques, while acting as a human Quality Gate. Leveraging my experience, I dictate the architecture, anticipate edge cases, and eliminate technical debt from the first line. The product is delivered 2 to 3 times faster, stable, and performant.

MY TWO PILLARS OF INTERVENTION:
- Web (Claude Code Velocity): I design and deploy your SaaS platforms and MVPs in record time, like my creations Boostender (AI-assisted RFP) and MazalDay.com.
- Mobile (Cutting-edge Expertise): Modern Kotlin & Jetpack Compose code, Clean Architecture, MVVM, and iOS mastery (Swift/SwiftUI).

REFERENCES:
- AI Projects: Full-stack creation of platforms connected to LLMs (Claude, OpenAI).
- WeMoms (Android Lead): Management, Compose/Coroutines migration, iOS development.
- Voodoo & Mappy (Lead/Senior): Architecture redesign, global advertising SDK, custom GPS (Mapbox).

MISSIONS: Dev from scratch (MVP/Scale), audit & legacy redesign, AI/LLM integration, and team mentoring to integrate Claude into their workflow. Available for Full Remote (France & International).
