About Me
I am a Software Engineer with a PhD, twelve years in academic research and three years in professional industry engineering. At Procore I build production backend services and platform features in C#, ASP.NET Core, and TypeScript. My academic foundation is in algorithm design, data structures, and complexity analysis, with research in computational geometry and graph theory. I focus on solving complex problems through clean, maintainable, and well-tested software.
