What I'm looking for

I’m looking for a role where I can ask the right questions, build reliable dashboards and reporting, and help teams make decisions with confidence—using SQL, Python, Power BI, and clear data storytelling.

I’m a Data Analyst who believes analysis starts with asking the right questions. I bring both the technical skills and the curiosity to turn messy data into decisions teams can actually trust through dashboards, cleaned datasets, and clear stakeholder reporting.

In freelance work and in-house roles, I’ve built end-to-end pipelines and analytics that reduce manual effort while improving accuracy. I designed automated data collection using the YouTube Data API and Python, standardized raw API data, and delivered Power BI visuals that supported influencer identification—while also tracking 500+ customer transactions monthly with an end-to-end pipeline.

I’m especially energized by KPI reporting, segmentation, and trend analysis that lead to action. I’ve developed 3+ interactive Power BI dashboards for revenue trends, customer retention, and product performance, and used SQL and Python to uncover growth opportunities that informed quarterly marketing strategy—backed by projects like Netflix content visualization and water access analytics.
