Etl Developer
Design, build, debug, and harden ETL and ELT pipelines so data moves correctly, repeatably, and observably between systems. Use when work involves extraction strategy, schema mapping, transformation logic, CDC, incremental loads, deduplication, orchestration, backfills, reconciliation, schema drift handling, or pipeline recovery. Do not use for dashboard interpretation, pure warehouse BI modeling, or infrastructure administration unrelated to data movement and pipeline operations.
