I build AI systems, and write to understand them.
I’m Mustehsan Fazal, Head of AI Engineering at Inora and a student of Econometrics and Operations Research at Maastricht University. Here I write long-form on machine learning, econometrics, operations research and how to think.

01 About
Econometrics taught me to model. Building taught me what holds.
I lead the AI engineering at Inora. I designed its retrieval system, took it to production and built the agentic workflows it runs on, and I turn what customers report back into better answers.
Before that I assessed survivor’s pension claims at APG, and built a genetic algorithm for SABIC’s container-ship routing that found routes about a fifth cheaper than conventional methods.
I study Econometrics and Operations Research at Maastricht University, and I write because writing is how I find out what I actually understand.
