Vahid Yousefzadeh
Software engineer and architect
I’m a software engineer and architect with over 10 years of experience building desktop and web applications. My work focuses on engineering software, high-performance graphics, and automation.
Over the past decade, I’ve developed tools for Revit and AutoCAD at SOFiSTiK and auxalia in Germany. Before that, I founded RebarDraw, software that automates construction drawings from structural design data.
I work primarily with C#, .NET, and TypeScript, building interfaces with Svelte and React, and browser graphics with WebGL2.
