About Nathan

Web Developer | Next.Js | Node.Js | TypeScript

Looking for a web developer who can transform your ideas into high-performing, scalable applications? I help companies create modern websites and full-stack applications using Next.js, React.js, Typescript, and NodeJS. My goal: to deliver fast, reliable, and easy-to-maintain products.

I am a full-stack web developer, specializing in Next.js front-end and back-end. I am involved in the entire cycle: design, development, API integration, deployment, and production monitoring. I work on both scratch projects and existing applications that need to evolve.

I have already completed various projects: developing front-end interfaces in React.js and Typescript, creating secure back-ends with NodeJS and Express, implementing SSR with Next.js, integrating payments and external APIs, as well as optimizing performance for SaaS or high-traffic websites.

My approach is turnkey: you receive a functional, stable, and maintainable product, with clear and documented code. Each project is designed to be scalable to facilitate your future updates.

I use a modern and proven stack: React.js, Next.js, Typescript, NodeJS, Express, PostgreSQL, MongoDB, TailwindCSS, Git, Docker. I apply development best practices (CI/CD, code review) and agile methodologies to ensure regular follow-up and transparent communication.

Need a Next.js / React.js / Typescript / NodeJS web developer for your next project? Contact me today: we can chat via video call to clarify your needs, and I guarantee a quick response within 24 hours.
