About Mohammed

I've had the opportunity to rethink architectures, optimize APIs, develop microservices, and also design ergonomic and intuitive interfaces. Because a good product isn't just a solid backend or well-styled front-end, it's a fluid and coherent experience.

I've worked on various projects, from finance (BforBank, Société Générale) to energy (TotalEnergies), including hospitality, e-commerce, and embedded systems. Each mission reinforced my conviction: code quality and user experience are investments, not options.

My playground:

✅ Fullstack Development: TypeScript, NestJS, React, for scalable, performant, and maintainable applications.
✅ Architecture and Optimization: Robust microservices, performant APIs, redesign and improvement of complex systems.
✅ User Experience and Ergonomics: Intuitive interfaces, fluidity, accessibility, and front-end performance.

What I bring to a project:

✅ Efficient and Maintainable Code: No unnecessary complexity, just well-thought-out solutions.
✅ Fullstack Expertise: 10 years of experience between solid backend and ergonomic front-end.
✅ User-Centric Approach: A good product is a balance between tech and experience.
✅ Craftsmanship Mindset: Clean code, tests, CI/CD, quality above all.
✅ Real Propositional Strength: I don't just execute, I challenge and optimize.

Today, as a freelancer, I support companies in realizing their web projects by designing performant, scalable, and well-thought-out applications.
