Back to original languageAbout Nicolas
Full-stack developer with 3 years of experience in startups, I design and improve web applications with React / TypeScript on the front-end and Java Spring Boot + MongoDB on the back-end.
I am comfortable with interface redesigns, complex aggregation queries, automated testing pipelines, and Docker deployments. I have also worked with AWS environments, set up test suites with Spring Test and Vitest, and developed full-stack applications with Next.js and Tailwind CSS.
My experience covers both REST API and microservice development in Java Spring Boot and the creation of modern interfaces in React TypeScript. I integrate CI/CD practices into my workflows to deliver reliable and maintainable code.
What sets me apart: I integrate quickly into existing projects, I quickly understand business constraints, and I deliver structured and maintainable code. No bullshit, clear scope, defined deliverables.
Ideal for: one-off or recurring remote missions, feature development, debugging & stabilization, internal tooling.
