Building Production Agents with LangGraph

Design agents as explicit state machines instead of prompt spaghetti. You will build a typed graph with conditional edges, add checkpointing so runs are replayable, implement retry and refinement loops, and ship an agent that degrades gracefully when a model call fails. Ends with a production deployment that handles concurrency, idempotency and observability.

Multi-Agent Systems: Coordination Patterns

When one agent is not enough: supervisor architectures, hierarchical delegation, shared scratchpads and message-passing protocols. You will implement a research team that plans, splits work, critiques its own output and reconciles conflicting findings, then measure whether the added complexity beat a single well-prompted agent.

Apache Airflow: Orchestration You Can Debug at 3am

Idempotent tasks, correct backfills, sensible retry semantics and the execution-date confusion that causes most Airflow incidents. You will build a pipeline that is safe to re-run, alerts on the right failures, and does not silently skip a day when a DAG is paused.
