Description

German developer seeking Java projects in Belgium or France.

Allow me to introduce myself briefly:

I am a German developer, but I lived and worked in Luxembourg for eight years, so I am fluent in French (as well as German and English). I am looking for Java development projects in Belgium or France.

I have 30 years of experience in development and project management in Germany, Luxembourg, and China.

By collaborating with me, you will benefit from international expertise, an asset for most projects bringing new perspectives and innovative ideas.

Technologically, my areas of expertise are Java/J2EE development (fullstack) with SQL/MySQL/Oracle databases and web application access.
