The engineer

Ammar Khan

Structural engineer New Jersey 6+ years in bridge design

I'm a licensed Professional Engineer (PE) in New Jersey, specializing in structural and bridge engineering. Beyond my day-to-day engineering work, I enjoy exploring technology and developing practical tools that make structural design, analysis, and review more efficient. My goal is to simplify everyday engineering calculations without compromising accuracy or reliability.

While reviewing calculations, I often need quick answers. Is the proposed camber reasonable? Does the maximum girder moment make sense? Not every check warrants opening SAP2000 and building a model from scratch. So, I started developing simple tools to make my own reviews faster and more efficient, and figured other engineers might find them useful too!
