Backend Engineer × AI-Native Builder

DavidMatosyan

Claude writes most of my code. I do the parts AI can't — knowing what the product needs, catching what's wrong, shipping what's right.

01 — How I work

Three years of fintech backend taught me what production code has to survive. Now I use that judgment to direct AI instead of typing everything myself.

01

Direct.

I break the product problem into instructions AI can execute. Scope, constraints, edge cases — the thinking is mine.

02

Review.

Every line gets read. Payments code taught me what breaks in production — that's what I hunt for in AI output.

03

Shape.

AI gives options; the product decides. I cut what doesn't serve it and ship what does.

This site is the proof — directed by me, built by Claude, reviewed line by line.
