About Herbert

Fullstack Developer with over 7 years of experience, I design and develop complex mobile and web applications with React Native, React, and Node.js.

I have worked on demanding projects: optimizing forms with 100+ fields at Cultura, mobile applications deployed on iOS and Android stores, fullstack architectures with authentication, advanced state management, and unit testing.

I pay close attention to user experience and gladly collaborate with designers to refine interface ergonomics and consistency — convinced that a good product is born as much from good UX as from good code.

What characterizes me: a methodical approach, constant concern for code quality, and a real ability to collaborate with product teams to transform functional specifications into solid technical solutions.

Currently available for freelance missions or a permanent position — remote or hybrid around Bordeaux.
