About Felix

C++ / C# / Python Software Engineer for Simulation, System Logic, and Performance Architecture

I develop performant and maintainable software systems that remain stable, understandable, and long-term extensible even with complex logic.

My focus is on the structured development of logic and simulation systems, as well as the clear separation of responsibilities (logic, data, presentation). The goal is to create systems that do not become unstable with increasing complexity, but remain clear, testable, and efficient.

I support teams in systematically implementing complex requirements, structuring existing codebases, and solving technical problems sustainably – with a focus on performance, maintainability, and scalability.

Key Areas:
• Development of complex logic and simulation systems
• Refactoring and structuring of existing C++, C# and Python codebases
• Implementation of state machines, grid/path systems, and AI logic
• Performance optimization and low-level system development
• Analysis and solution of technical problems in existing projects

I work analytically, structurally, and solution-oriented – with the goal of developing systems that not only function but also remain understandable and maintainable in the long term.

Typical Application Areas:
• Simulations and algorithmic systems
• Logic-driven applications (e.g., game mechanics or automation systems)
• Tools and technical prototypes
• Backend logic in C++, C# and Python
• Low-level system applications with clear architecture
