I will build a custom ai agent using python, openai, and fastapi

Most "AI agent" gigs on Fiverr are a few nodes wired together in n8n or Zapier. That holds up until your workflow needs real logic - branching, validated output, retries when an API call fails, or multiple models coordinating with shared memory.

I build agents in code: Python, FastAPI, and the OpenAI Agents SDK - the same architecture behind a production system running 20 coordinated agents on real user data every day.

Every tier ships as a live, working service - deployed to your own hosting account, full source code included. Yours from day one, not a zip file to figure out alone.

What grows with scope:

- Single-purpose agent (drafts, classification, summaries) - from 3 days

- Multi-agent workflow with a working interface to trigger and view results

- Production system with memory, automated quality checks, and a full dashboard

Structured, validated output (Pydantic). Retry and rate-limit handling built in from day one, not bolted on after something breaks in production.

Works with OpenAI, Anthropic, or Gemini - you provide access, I'll help set it up if needed.

Tell me exactly what the agent should do, and I'll scope it precisely.
