My skills include: - Databases: SQL, MySQL, Oracle, PostgreSQL, SQL Server. - Data integration: Fivetran, Stitch, Airbyte, Matillion, Azure Data Factory, Talend. - Data transformation: SQL, dbt, Python, Airflow, Dagster. - Data warehousing: AWS Redshift, BigQuery, Azure, Snowflake, Panoply. - Data visualization: Tableau, Microsoft Power BI, Looker, Metabase, Google Data Studio (now Looker Studio), Domo, AWS QuickSight, Klipfolio, QlikView/Sense, Mode, Superset. All work is completed by me, and you can be assured that I will not outsource to anyone else. I believe that clear, transparent and regular communication goes hand in hand with project success and I will always ask dozens of question to make it happen. I pride myself on providing the highest quality of work, and will never complete a project until the client is fully satisfied.
