Working with product, analysts, and frontend engineers on features end-to-end.

Python (or other applicable languages), FastAPI, PostgreSQL, Docker, Kubernetes, AWS, GCP, OpenTelemetry, agent frameworks.

You may not have used every one of these, but you should have shipped production systems with most of them.

Engineers who are curious about LLMs without being credulous about them. Engineers who can move quickly when the path is clear, and who slow down for the parts that need care. Engineers who reach for an abstraction when it earns its place. Engineers who care about the domain they are working in as much as the tools they are using.
