What I'm looking for

I’m looking for a role where I can own data quality and dashboard-ready reporting—using SQL, Power BI, and clear stakeholder communication—to support operational decisions in a remote, collaborative environment.

I’m a detail-oriented Data Analyst and Data Operations Analyst who delivers error-free, decision-ready reporting through strong data quality, validation, and cleaning. In remote, multicultural teams, I translate complex datasets into stakeholder-ready insights using SQL, Excel, and Power BI.

Recently, I designed and delivered 4 data visualizations for a 13-person remote team, documenting transformation logic to keep results consistent and reproducible. I also cleaned and transformed 100,000+ row datasets with Power Query and wrote 10+ optimized SQL queries across datasets to uncover trends and support reliable dashboard development. Before shifting fully into analytics, I worked as an Intern Health Analyst / Pharmacist, auditing 50+ patient medication histories and synthesizing multi-source clinical data into clear, actionable summaries—training the precision and accountability I bring to every analysis.
