What I'm looking for

I’m looking to grow in a data-driven role where I can build BI dashboards, standardize KPIs, validate data, and automate reporting to improve marketing and operations performance with cross-functional impact.

I’m a Senior Data Analyst with 3+ years of experience in business intelligence, data analysis, and dashboard development, driving data-driven decision-making across marketing and operations. I coordinate across data, marketing, and QA teams to align priorities across 10+ stakeholders, and I guide junior analysts through query reviews and standardized reporting logic.

I build and maintain high-impact dashboards (15+ reports) for executives and cross-functional teams, defining and standardizing business KPIs and data validation processes. I improve reporting efficiency by optimizing SQL and implementing scheduled queries in BigQuery, and I also support workflow automations (AppSheet) to improve process organization and data accessibility.
