Python developer for LLM integration and automation

We need a Python developer with solid experience connecting language model APIs to real workflows. You will integrate LLMs into Python apps, build automations, write backend services, work with REST APIs and webhooks, and use structured prompts and tool calling so the results stay reliable.

Nice to have: LangChain or similar frameworks, retrieval-based systems, FastAPI, PostgreSQL and Docker.

Please describe a similar automation you built.
