The AI engineer assembles systems on foundation models — they don't train them. Tap a layer: the field's options, and the pick tuned to your stack (TS/Go, self-hosting, MCP).
THE WIRE
Python runs ~95% of the AI ecosystem. Your TS covers frontends, demos, and TS-native agent frameworks.
THE OPTIONS · ★ = learn first
★
Python + FastAPI — the must-have — every framework assumes it
★
TypeScript — you already have it; Mastra & Vercel AI SDK are TS-native
·
uv / poetry — modern Python dependency management
FOR YOU
Your gap is small: ~1 week to be functional in Python + FastAPI. Everything else transfers.
