Python AI engineering teams building type-safe agents and extraction pipelines frequently search to hire a freelance PydanticAI, Instructor & structured LLM output programmer. I am Aldian Fazrihady, a Senior Freelance AI Application Engineer and Python Architect.
Core PydanticAI & Structured Extraction Capabilities
- Type-Safe Agent Engineering with PydanticAI: Building production agents with dependency-injected context (`RunContext`), streaming Pydantic validation, and model-agnostic support across OpenAI, Anthropic, Gemini, and Groq.
- Self-Correcting Validation Retries (Instructor): Feeding Pydantic `ValidationError` tracebacks automatically back into the LLM so malformed field values, invalid enums, or failed cross-field invariants self-heal before reaching your database.
- High-Concurrency Asyncio Extraction: Processing thousands of unstructured documents concurrently with `asyncio.Semaphore` rate controls and FastAPI endpoints.
Frequently Asked Questions
Why use PydanticAI or Instructor instead of raw JSON mode?
Raw JSON mode only guarantees valid JSON syntax, not domain validity. Pydantic validators enforce business rules (such as date ranges, checksums, and database foreign-key lookups) and automatically re-prompt the model when a rule fails.
