Data Engineering & Autonomous AI Agent Integration (PySpark, Delta Lake & LLM Tool-Calling)

We need an experienced Data Engineer and AI Agent developer for a quick 45-minute micro-task ($30 fixed) to debug a single 80-line Python script connecting a Databricks Delta Lake table to an LLM tool-calling agent. You will fix a minor schema validation bug in our PySpark metadata query function and tighten the JSON structured output definition used by our autonomous agent workflow. The only deliverable is the corrected Python file, this is a fast, self-contained paid trial to shortlist a lead architect for our upcoming Lakehouse and AI Agent production rollout.
