that's yours.Technical stack:Web app: React 19, TypeScript, Vite, TanStack (Router/Query), Tailwind, typed OpenAPI clientAI layer: the tutor agent is built on Sinas , an open?source self?hosted platform for AI agents; the agent's configuration and behavior are part of the product you'll shapeResponsibilities:Build new functionality across the full stack - primarily the API and web appEvolve the product workflow: changes to the AI tutor's configuration, the API, and the frontend/UX as one coherent wholeBuild dashboarding/reporting for the clientKeep the platform healthy in production (scalability groundwork is largely done)Own the client relationship: intake requirements, propose solutions, scope, estimate, push back when needed, and communicate progress - the client is non?technical and refreshingly direct, and appreciates the same in returnConsult the original WeAreBrain team when you want a second opinion on bigger decisionsWho we're looking for:A capable mid?level full?stack developer - you can own a production system independently, and you know when to ask for advice rather than getting stuckSolid with Python (FastAPI or similar) and React/TypeScript;
