What I'm looking for

I’m looking for a role where I can lead discovery sessions and turn business needs into data models, ETL/API integrations, and Power BI semantic layers—while improving KPIs, data quality, and governance in an Agile, collaborative environment.

I’m a Technical Business Analyst with 7+ years in retail, digital marketing and banking, specializing in translating business requirements into data models, ETL pipelines and API integrations that enable decision making.

I lead discovery sessions, design semantic layers in Power BI, and manage backlogs in Agile environments with distributed teams. I’ve built automated analytics pipelines (BigQuery + Power BI), improved query performance by 40% through SQL optimization and standardized KPI definitions, and reduced weekly consolidation time by 75% through Power BI dataflows and SQL automation.
