I help companies turn fragmented data into trusted analytics used by leadership and operations.
I specialize in building modern data platforms, from ingestion to analytics, using dbt, SQL, cloud data warehouses, and BI tools. My work focuses on clarity, correctness, and business impact, not just pipelines.
What I typically help with:
Designing scalable analytics engineering layers (dbt, dimensional modeling)
Building and optimizing ELT pipelines into Snowflake / BigQuery / Redshift
Creating trusted metrics and dashboards for leadership and operations
Improving data quality, testing, and CI/CD for analytics
Migrating legacy reporting to modern data stacks
I work closely with stakeholders to translate business questions into clean data models and actionable insights.
If you need analytics that people actually trust and use, let’s talk.
