Backend-firstfull-stack,for real products.

Behind the commits.

Amirhossein Aghayari at his desk
The desk where it happens

I care about building systems the right way, not just writing code.

Backend is where I go deepest, but I like owning a feature end to end: from the API and the data model to the interface people actually use.

Focus
Backend engineering, software architecture, clean code
Approach
Reliable, maintainable and practical beats clever
Routine
Some coding, learning and reading every day, plus regular exercise
Believes
Progress comes from consistency, curiosity and commitment
