- Convert Oracle SQL/PLSQL and database logic into optimized Snowflake SQL and modern cloud data patterns.
- Develop production-grade Apache Airflow DAGs for data ingestion, transformation, scheduling, dependencies, monitoring, and error handling.
- Design efficient Parquet-based data pipelines, including extraction, staging, loading, partitioning, compression, and schema evolution.
- Evaluate and implement Snowflake Hybrid Tables for appropriate transactional/operational workloads.
- Identify, document, and migrate business rules embedded in Oracle PL/SQL, ETL processes, database objects, and application logic.
- Determine appropriate implementation of business rules using
- Snowflake SQL, Python, dbt, Airflow, or a Business Rules Engine (BRE).
- Build automated data reconciliation, validation, and business-rule regression testing between Oracle and Snowflake.
- Perform Snowflake query, warehouse, pipeline, and data-load performance optimization.
- Collaborate with architects, DBAs, application teams, business analysts, QA, and data engineering teams.
- Support production cutover, troubleshooting, and post-migration stabilization.
