Freelancer profile translated to English.
Back to original languageAbout Nicolas
Backend & SaaS Developer, I primarily work with Next.js, React, and backend APIs (Node.js, Java/Spring). I am involved in complete web projects, from frontend integration to production deployment, including data management and performance optimization.
I am accustomed to working on business applications (management, dashboards, internal tools) with real-world constraints: authentication, secure API calls, data processing, file generation (Excel, PDF), etc.
I am autonomous in my assignments and adapt easily to existing environments (existing code, teams, technical constraints). I favor simple, maintainable, and quickly deployable solutions.
Available for full-stack or frontend assignments, with a preference for concrete projects where efficient delivery is key.
