Freelancer profile translated to English.
Back to original languageAbout Raoul
I am a fullstack web developer specializing in Next.js, React, Node.js, and TypeScript.
I am involved in the design, development, and deployment of web and mobile applications, with a particular focus on code quality, reliability, and performance.
I have developed several complete products on my own, including REPS, a SaaS platform for sports coaches with Stripe Connect payments, iOS and Android applications, as well as PARSEC, a real-time strategy game entirely developed and deployed by myself.
I enjoy complex challenges: backend architecture, database design, APIs, authentication, payments, real-time, performance optimization, and user experience.
I primarily work with Next.js, React, TypeScript, Node.js, PostgreSQL, Prisma, Tailwind CSS, and Stripe.
I am looking for missions where I can have a concrete impact on the product, propose relevant technical solutions, and deliver robust features, whether it's creating a project from scratch or evolving an existing application.
