> Software Engineer @ Motive

Location: Los Angeles, California, United States
Profile: https://flows.cv/justinzeng

Product engineer who works across the stack with a heavy backend and systems lean, and deep experience with AI-native development workflows. I spend most of my time in Rails, Postgres, and GCP, building APIs, owning pricing and inventory systems, and handling infrastructure and DNS work. I've shipped features end to end at both Series A and Series D startups, and I tend to gravitate toward the problems that sit between backend logic, data, and platform reliability. More recently I've been building tooling that leans on LLMs to automate workflows that used to be entirely manual.
