The Calculated Engineer
Soroush Hashemi

Opinions are cheap and surface-level understanding is dangerous. I analyze by going deeper — into the mechanics, the tradeoffs, and the assumptions others take for granted. My focus is where AI meets software engineering. I write for engineers who'd rather understand the risks first then move with confidence.

    Outside the Terminal

    I'm a heavy gamer — single-player, story-driven, and simulation. If it has a narrative arc, a system to optimize, or can teach me a new skill, I'm probably already 40 hours in. If you're up for a multiplayer game though, reach out and let's connect on PlayStation Network.

    I have a habit of reaching for math whenever a problem shows up — any problem. It's the same instinct that's driven physics since Newton, and driven me to Physics. Philosophy helps me calm down (and occasionally panic). And Neuroscience keeps reminding me how little one can be certain about anything, which keeps me grounded.

    As for visualizing music — I'm not giving that one away so easily. Let's grab a drink.
