I provide ongoing SQL, BigQuery, Looker, and Looker Studio development and support for businesses that need reliable data models and accurate dashboards.

I can help you build and maintain:

• SQL queries, tables, and views • BigQuery transformations and reporting datasets • Looker and Looker Studio dashboards • Data models and reusable reporting logic • KPIs, calculated fields, and dashboard filters • Data-quality and validation queries • Technical and data-lineage documentation

I can also investigate and resolve:

• Duplicate rows and incorrect counts • Broken or incomplete joins • Aggregation and granularity issues • Incorrect dashboard KPIs • Filter and calculated-field problems • Differences between source data and dashboard results • Slow or unnecessarily complex SQL queries

Each delivery includes tested logic, validation steps, and clear documentation. I focus on preserving your existing business rules while improving accuracy, maintainability, and dashboard reliability.

This ongoing service is suitable for regular SQL development, dashboard creation, BI maintenance, data validation, and troubleshooting.
