What I Do

Three Pillars of My Work

Leadership & Transformation

Servant leadership, Team Topologies, and the courage to transform.

Leading 20 developers through a major transformation -- not by directing, but by serving. Migrating a C# WinForms monolith to a modular SaaS platform while restructuring into stream-aligned teams, a platform team, enabling teams, and a complicated-subsystem team. My leadership philosophy: remove obstacles, foster ownership, invest in people's growth, and trust teams to solve the right problems.

Article - Call Center for Methods The idea of a central class for calling methods from different components aims to simplify complex applications. This method aggregator improves readability, maintainability, flexibility, and overall development structure.

Article - Default Interface Methods in C# 8.0 Software development requires code that is functional, modular, maintainable, and flexible. A key challenge is making services accessible without creating rigid dependencies.

Article - From Prompt to Pipeline: The GEEF Principle GEEF separates AI roles for generation, review, and finalization to iteratively improve quality, while convergence, cost, and reviewer calibration remain challenges.

Article - From the advisor in the background Anthropics Advisor Tool erweitert KI-Pipelines um eine strategische Beratungsrolle neben Ausführung und Prüfung. Im GEEF-Prinzip hilft diese Rolle vor allem, Grounding-Fehler früh zu erkennen — entscheidend ist damit die passende Rollen- und Modellverteilung.

Article - From Blueprint to Workpiece (Based on the GEEF Principle) A technical article on dynamically assembled multi-agent pipelines, self-improving system operation, and an open-source reference implementation.
