About Yavuz

Java / JavaScript Developer and Technical Project Manager with over 10 years of experience, I support companies in the design, development, and improvement of robust, maintainable, and scalable web applications.

My expertise covers full-stack development with Java/JEE, JavaScript, TypeScript, Node.js, PHP, Symfony, NestJS, Angular, and React.js, as well as REST API design, database modeling, automated testing, continuous integration, and Docker / Kubernetes environments.

Accustomed to large account contexts such as SFR, Dassault Systèmes, and Thales, I can act both in hands-on development and technical management: needs analysis, costing, work organization, code review, architecture improvement, technical debt reduction, and developer support.

Driven by regular technological monitoring, I constantly seek to improve my development practices, strengthen code quality, and propose more robust, maintainable, and scalable solutions.

I am looking for assignments where I can bring solid technical expertise, a pragmatic approach, and a real ability to structure projects and teams.
