Nicolas Guenin Senior frontend engineer

Hello.
I'm a Bordeaux based frontend engineer, with 10 years' experience, specializing in building the UI of web applications like SaaS, Self-Hosting, and E-commerce.

Through my experience, I make sure to take into account business and product rules, to ensure consistency between the code base and business needs.

I value pragmatism and efficiency, strive to respect best practices as well as certain principles such as SOLID or DRY, and modern programming approaches such as TDD and continuous refactoring enabling a quality code base, easily testable and maintainable by other developers.
