Mar 2005 - Present • 21 yrs 2 mos
For nearly two decades, I have been engineering robust software solutions for corporate clients and tech companies across Germany. Acting as a Senior Full Stack Developer, I have successfully bridged the gap between complex legacy enterprise systems and modern web technologies. My consolidated experience encompasses Lead and Senior Developer roles at established software firms in Frankfurt (including FORMAT Software Service GmbH, Softwarebüro Zauner, and D3 Mobile) as well as independent freelance consulting. Key Career Highlights & Expertise: 🚀 Modern Web & API Development: Engineered highly responsive web applications and internal enterprise tools using modern frameworks like Blazor and .NET Core. Designed, integrated, and maintained secure RESTful APIs and dynamic dashboards utilizing C#, PHP, and SQL. 💻 Desktop Software & Legacy System Mastery: Unlike many modern web developers, I possess deep, hands-on expertise in building, refactoring, and upgrading mission-critical desktop and legacy applications. I have spent years developing proprietary ERP programs and complex desktop architecture using C++, MFC, Delphi, C#, and VB.NET. If you have a legacy system that needs saving, fixing, or migrating to the web, I have the exact niche skill set required. ⚙️ Data Automation & Database Architecture: Developed intelligent data analysis and workflow automation tools using Python, significantly reducing manual workload for businesses. Designed, optimized, and managed complex relational databases (SQL Server, PostgreSQL, MySQL) to ensure high performance and data integrity. The Value I Bring: When you work with me, you are partnering with a battle-tested software engineer. I don't just write code; I understand business logic, prioritize clean architecture, and know exactly how to deliver scalable, bug-free, and maintainable products from scratch.
