How to Structure a Codebase for Scale and Maintainability

Hi, I'm

Ali Hesari

Engineering lead and founder. I built OwlStack, an open-source automation framework, and Profitable, a real-time stock-market analysis platform. Today I run PorterBridge, a studio building products that bring AI into industrial systems.

I started as a mining engineer at the University of Birjand before moving into software. Now I bring the two together, building AI and automation systems for industry and resources.

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.
