Beyond the Managed Boundary
While .NET is powerful, some problems require dropping down to the metal. I specialize in building robust, memory-safe communication layers between C# and C/C++ libraries, enabling the use of industry-standard tools within modern .NET architectures.
Custom Native Bindings
Expertise in writing manual P/Invoke definitions, strict marshalling, and handling memory ownership. Creating high-fidelity wrappers for libraries like QPDF, PDFium, and LibHaru (as seen in my open source examples).
Advanced Interop Strategies
Handling complex C++ types not supported by standard P/Invoke using C++/CLI bridges or custom "flattener" C layers. Integrating specialized hardware drivers and legacy DLLs.
Performance Optimization
Utilizing Span<T>, Memory<T>, and unsafe pointer arithmetic to eliminate copying when passing data across the managed/native boundary. Deep understanding of IL generation for critical hot paths.
Recent Work in Interop
- Qpdf.Native: A raw binding to the QPDF library, exposing its powerful PDF manipulation capabilities to .NET.
- PDFiumCore: Low-level access to Google's PDFium rendering engine.
- LibHaruCore: A modern wrapper around the LibHaru PDF generation library.
