Summary
👤
Senior🎓
Top SchoolGrégory Koenig is a web developer based in Luxembourg with eight years of hands-on experience building responsive websites and mobile apps across startups, agencies and research institutions. He combines a pragmatic full‑stack skill set—JavaScript, PHP, Python, SQL, C# and legacy COBOL—with a taste for software craftsmanship and extreme programming practices. His background spans Drupal migrations and containerization at Actency, React Native and Node.js in early startup work, and performance and automation wins at Autogriff that cut processing time by up to 90%. More recently he tackled large-scale data update jobs and intranet tooling for Crédit Mutuel via CGI before joining LISER to support socio-economic research platforms. A former Epitech student and occasional guest speaker, he pairs technical curiosity (Haskell and Elm experiments) with a user-focused approach to shipping reliable, maintainable systems.
