Hi, I'm

Ali Hesari

Engineering lead and founder. I founded OwlStack — an open-source automation framework — and Profitable, a real-time stock-market analysis platform. I run PorterBridge, a studio building products at the intersection of AI and industrial systems.

I started as a Mining Engineer at the University of Birjand before moving into software, and I’m now bringing both back together — building AI and automation systems for industrial and resource contexts.

I also run Tech Farsi, a Persian-language software-education platform with five active courses. I write here about engineering, founding, and the decisions behind both.
