I'm a software engineer with a bias for simple systems and careful interfaces. Most of my work sits close to the data layer — APIs, pipelines, and the infrastructure that keeps them honest.
I care about the parts of engineering that don't show up in a demo: clear failure modes, migrations that can be rolled back, and code the next person can read without a meeting.

Testimonials
Morteza has the rare habit of leaving a system simpler than he found it. Our on-call load dropped measurably after he rewrote the ingestion path.
The best reviewer I've worked with. He finds the assumption you didn't know you'd made, and says so without making it a big thing.
He explains technical trade-offs in a way that lets non-engineers make a real decision, rather than just approving one.
