Back to original languageAbout Nicolas
You have a product to build or get back on track.
Not just code. A product that works, that lasts, and that you can evolve without breaking everything.
I am Nicolas, a Fullstack React / React Native developer. I work on web and mobile projects from end to end: from the idea or mockup to the deployment, including architectural choices, third-party integrations, and taking over existing bases.
I work on React, Next.js, React Native, Expo, and Node.js, whether it's launching an MVP in a few weeks or strengthening an existing production platform.
What I do specifically:
⚛️ Web applications, SaaS, dashboards, business interfaces
📱 iOS / Android mobile applications with React Native / Expo
⚙️ Node.js APIs, authentication, payments, third-party integrations
🧱 Taking over existing projects: stabilization, refactoring, quality improvement
🚀 Quick MVPs to validate an idea without creating unmanageable debt
What sets me apart:
I know how to find the right balance between speed and rigor. For an MVP, I move fast and make decisions. For a production product, I structure it for longevity. In both cases, I understand the business stakes behind technical choices and help you avoid getting stuck in six months.
I have worked on marketplaces, SaaS platforms, R&D projects, and environments where speed was essential without breaking existing systems.
What you can expect:
âś… Real autonomy on the subject
âś… Clean and scalable architecture
âś… Direct and honest communication
âś… A profile that thinks product, not just tickets
If you have a project to launch, accelerate, or put back in order, let's talk.
