Sébastien Gouyer

Looking for a profile capable of building and optimizing your applications while maintaining a clear vision of the overall architecture? With 20 years of experience, I act as afullstackdeveloper to deliver quickly, while bringing an architect's approach to secure your technical choices and guarantee the longevity of your projects.

I master the entire application chain:backendin **Java**, **Spring**, Spring **Boot**, and frontend in **Angular**, TypeScript. I develop end-to-end features, fix bugs, optimize performance, and refactor existing code to make it clearer and more efficient. In parallel, I ensure that the application architecture is based on solid and scalable foundations.

Throughout my career, I have led various types of projects:

– creation and deployment of complete business applications,

– technical redesign and modernization of existing architectures,

– performance improvements on critical platforms,

– implementation of best practices around DDD,TDD**, **hexagonalarchitecture, and **clean code**.

My promise is to deliver turnkey applications that are reliable, documented, and easily maintainable. I help you move forward while reducing technical debt and securing your long-term developments.

In terms of methods, I combine operational pragmatism (move fast, deliver regularly) with architectural rigor. I use modern frameworks from the Java ecosystem as well as recognized software quality practices.

If you are looking for a hybrid profile between an experienced developer and an architect, I can assist you starting now. I am available for an initial video call to understand your needs and define the best approach together. I generally respond within 24 hours and can start quickly.
