Nazir
The structural engineer whodesigns the structure.
I design buildings that stand safely, model them so nothing clashes on site, and build the software that makes both jobs faster.

About me
A mason's son who learned to build on paper first.
I grew up in Faisalabad watching my father, Nazir Ahmad, build with his hands. I lost him in 2016, finished my civil engineering degree through the hardest years of my life, and founded Defteng in 2021.
"Adversity does not define a person. With enough willpower, one can surpass any barrier to achievement."
- CEO and Founder of Defteng (Pvt) Ltd
- 2,000+ buildings designed and issued with producer statements
- Clients in New Zealand, Australia, the US, the UK, Belgium and Pakistan
For students and juniorsEverything I wish someone had handed me at 21.
Sample project sets, the tools, and long write-ups on the things that trip people up. Free, no sign-up.
