I turn complex business rules into reliable software. Backend Developer in Fribourg, Switzerland: Python/FastAPI in production, current focus C#/.NET business applications.
My professional background is mainly in Python backend development, APIs, SQL, data processing, and workflow automation. My current engineering focus is C#/.NET, ASP.NET Core, EF Core, SQL Server, and related application technologies.
I am particularly interested in software where business rules, data integrity, and real-world processes matter: operational systems, administrative workflows, reliable APIs, and tools built around concrete user problems.
A web application for preparing temporary event permit dossiers in Fribourg, Switzerland.
Built with C#/.NET and ASP.NET Core Razor Pages, it turns publicly available administrative requirements into a guided questionnaire with required actions, documents, deadlines, confirmation points, and links back to official sources.
The project is deployed publicly and keeps its decision rules tied to a reviewed inventory of official Ville de Fribourg, Canton de Fribourg, and OCN sources.

Before focusing on C#/.NET, I worked professionally with Python backend services, API integrations, SQL, data processing, and internal operational tools.
I also previously worked as an HR Business Partner. That experience gave me direct exposure to changing requirements, cross-functional processes, operational constraints, and the gap that often exists between a business rule on paper and its actual implementation in software.
