What I'm looking for

I’m looking to build scalable, high-performance C#/.NET backend libraries—especially computational geometry and AI-enhanced workflows—where I can drive performance optimization, strong testing, and cross-functional collaboration.

I’m an accomplished Senior Software Engineer with 10+ years building robust C# libraries and scalable backend systems for complex applications. I translate intricate technical requirements into efficient solutions using .NET frameworks, advanced algorithms, and data structures.

In my recent role, I developed high-performance C# libraries on .NET Core for processing complex geometrical data models, supporting computational design workflows and reducing processing time significantly. I focused on performance-critical engineering decisions—optimizing memory usage and execution speed—while building modular components, unit tests, and validation frameworks.

I also engineered C# libraries for AI-powered design validation tools, optimizing computational routines through performance profiling and implementing scalable data access layers with Entity Framework for real-time synchronization. Previously, as a Founding Engineer, I created foundational .NET/C# libraries for structured-data algorithmic processing, implemented integration layers, and strengthened reliability through debugging and performance optimization in IT consulting environments.
