What I'm looking for

I seek remote roles where I can build dashboards, automate processes, and deliver actionable analytics within collaborative, goal-oriented teams.

I am a statistician and data professional with experience building BI solutions, dashboards, statistical models, and automated processes to support strategic decision-making. I combine technical depth in R, Python, SQL and Power BI with a user-centered approach to data accessibility and visualization.

My background includes roles at public agencies and private firms where I developed Power BI and Looker Studio dashboards, performed ETL and data auditing, and delivered analyses for performance monitoring, churn, billing and operational oversight. I have led cross-team negotiations, supported sensitive-data projects, and translated complex data into actionable business insights.

I am focused on automation, process optimization and trust-building, and I continue to deepen my skills through a Data Science bootcamp and targeted courses in AI, cloud (GCP/BigQuery), and advanced BI tooling.
