Stack

Responsibilities

• ▹Build features that ship fast: new capabilities, MVPs and internal tooling across the FastAPI (Python) + PostgreSQL backend and React (TypeScript) frontend, getting things in front of clients quickly

• ▹Debug live, high-volume systems: diagnose and resolve issues for agents making thousands of daily phone calls, where reliability and call quality directly affect patient and provider experience
• ▹Turn client feedback into product: close the loop with AI PMs and engineering, surfacing patterns across clients and feeding them back into the core platform
