About Chris-Robin

Ich unterstütze Unternehmen dabei, komplexe Webplattformen zuverlässig zu bauen, weiterzuentwickeln und in Produktion zu bringen. Mein Fokus liegt auf Full-Stack-Entwicklung, technischer Architektur, Frontend, Backend, Datenmodellen, Suche, CI/CD, Deployment und Monitoring.

Besonders stark bin ich in Projekten, in denen nicht nur Umsetzung, sondern auch technische Verantwortung gefragt ist: bestehende Systeme verstehen, Anforderungen schärfen, Architekturentscheidungen treffen und pragmatische Lösungen liefern. KI-Tools nutze ich routiniert für Recherche, Prototyping, Refactoring, Tests und Dokumentation, immer mit sauberer technischer Prüfung.

Typische Projekte sind SaaS- und Plattformentwicklung, interne Tools, datengetriebene Webanwendungen, Migrationen, Performance-Verbesserungen und technische Modernisierung. Außerdem unterstütze ich Teams durch Code Reviews, Mentoring und klare technische Kommunikation.
