About Levin

I build the parts between “the idea works” and “the operation is reliable.”

I design and test workflow automations with n8n, APIs, JavaScript, SQL and AI-assisted decision steps. My work focuses on systems that need more than a polished happy-path demo.

Working style

Reliability-first, evidence-backed.

I validate inputs, use stable idempotency keys, prevent duplicate records, keep risky actions behind human approval and document the boundary between local verification and live deployment.

The result is not only an automation canvas. It is a system another person can inspect, test and maintain.

Clarity before complexity

The workflow should explain the business rule, not obscure it.

Safety before speed

Automation stops where authority, consent or confidence stops.

Evidence before claims

Public language follows what the tests actually demonstrate.
