What I'm looking for

I'm looking to build reliable analytics systems that turn growth, marketing, and customer data into clear decisions, collaborating directly with stakeholders and automating manual reporting workflows.

I've delivered five end-to-end data engagements for businesses in food retail, automotive retail, and legal services, replacing manual reporting with validated data systems, scheduled pipelines, and real-time Slack alerts.

Across Gameflip, BairesDev, and OA Leads, I've used SQL, Python, Tableau, Airflow, Snowflake, and Databricks to automate KPI tracking, analyze acquisition and conversion, and give stakeholders clear reporting they can act on.
