Nicola E.

I help organizations move from data confusion to data clarity by building analytics systems that not only visualize numbers but transform the way teams make decisions.

🏆As a Top Rated Plus Freelancer (Top 3% on Upwork) and a Tableau Certified Data Analyst with a Master’s Degree in Information Systems, I partner with companies to design and implement end-to-end data solutions. These include everything from data pipelines to executive dashboards, making information accurate, automated, and actionable.

What I Do

I specialize in helping businesses turn raw, fragmented data into a single source of truth through interactive dashboards, advanced analytics, and automation.

Whether you are a healthcare provider optimizing operations, a university tracking marketing ROI, or an enterprise unifying reporting across departments, I create systems that connect everything so your data tells a clear and meaningful story.

Client Success Stories

Healthcare Company:
I helped a healthcare organization implement Row-Level Security (RLS) and develop seven automated Tableau dashboards. This reduced reporting time by 50% and significantly improved data efficiency. Leadership gained full confidence in their metrics and could make faster, more informed decisions.

Education Company:
I built a Return on Ad Spend (ROAS) model that identified the most profitable ad platforms. By comparing Google Ads, Facebook Ads, and LinkedIn campaigns, the marketing team could confidently reallocate their budget to the highest-performing channels. This improved campaign performance and reduced wasted ad spend.

These are the types of projects I value most: when data stops being overhead and starts becoming a strategic advantage.
