Evaluation-Driven LLM Development

Shipping an LLM feature without an eval suite is shipping a rumour. Build golden datasets from production traffic, write graders that correlate with human judgement, and wire regression gates into CI so a prompt change cannot quietly degrade quality.

Cloud Cost Engineering and FinOps

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.
