About David

As a React Developer and QA Engineer, my mission is twofold: to design high-performance web applications (React, Next.js, TypeScript) and to ensure their impeccable quality.

I will assist you in developing and implementing automated testing strategies (Cypress, Playwright) and continuous integration (CI/CD) to deliver a reliable, bug-free product.

Having both React and QA Engineer skills is a major asset for your project. Unlike a traditional developer, I integrate quality constraints from the moment the code is written.

Specifically, this means:
- Fewer back-and-forth exchanges during the acceptance phase: I detect and fix bugs before they occur.
- Controlled technical debt: I produce clean, maintainable, and testable code.
- Smoother deployment: thanks to test automation, your production releases are secured.
