About Raphaël

Senior full-stack developer, 9 years of experience designing and delivering reliable web and mobile applications, from idea to production.

I will guide you through the entire lifecycle of your projects — technical scoping, front-end and back-end development, deployment — to deliver robust and well-architected products, without multiplying intermediaries.

I primarily work with JavaScript / TypeScript and .NET ecosystems, as well as mobile development, and I am happy to adapt to your stack and specific needs. I also provide services in cloud deployment (Microsoft Azure, AZ-104 certified) and the implementation of best practices (CI, code quality, design systems).

What sets me apart: a true consulting and technical leadership role (backlog management, standards, team support), forged in demanding environments.

I can assist you with, among other things:
- Web and mobile projects, using the technologies I master
- API design and integration
- E-commerce journeys and payment funnels
- Design systems and reusable component libraries
- Database design and optimization
- Technical consulting, code review, and project scoping

And other needs depending on your project — don't hesitate to discuss them with me.

Available for contract or fixed-price projects. Let's talk about your project.
