Back to original languageAbout Guillaume
I am a multimedia engineer specializing in Fullstack Web development.
I primarily use React/NextJs, Angular, and NestJS frameworks to produce interactive web applications.
I work in conjunction with UI and UX Designers to produce high-performing and accessible applications, particularly through collaborative tools like Figma or Miro. I also attach great importance to code quality and maintainability (Linters, Formatters, Test Coverage, Documentation, etc.).
I usually work in an agile team and can support other developers in completing their tasks. I can propose technical solutions for the architectural challenges of modern web applications (Redux Pattern, MVC, Hexa Archi, etc.). I use CI/CD tools as well as major Cloud Providers to ensure continuous deployment of applications.
