Back to original languageAbout Nicolas
Java / Angular freelance developer specializing in the development of web applications, REST APIs, and business applications.
I help companies design and evolve robust business applications in Java and Angular.
Experienced Java / Angular developer, I work in demanding environments where code reliability and understanding of business needs are essential.
My experience in large corporate environments has led me to work on critical systems combining Java backend (Spring Boot, REST API), Angular frontend, and structured deployment processes (CI/CD).
What I concretely bring:
• Development of secure, performant, and maintainable REST APIs
• Design of clear, structured, and optimized Angular interfaces
• Evolutionary maintenance and refactoring of legacy code
• Analysis and resolution of production incidents
• Effective collaboration with business and technical teams
I place particular importance on:
• Code readability and maintainability
• Application performance and stability
• Autonomy and ability to adapt quickly to a project
• Clear communication with stakeholders
In parallel, I develop my own applications (Flutter / Firebase), which gives me a complete product, technical, and performance-oriented vision.
Based in the Alpes-Maritimes – open to remote.
Available to discuss Java / Angular opportunities.
