Data Analyst turning messy multi-source data into actionable dashboards and product decisions.
BoliviaWhat I'm looking for
I’m a Data Analyst who turns messy, multi-source data into dashboards and decisions that business and client teams actually use. I build and own the full BI pipeline in Power BI—from data connection and data modeling to DAX measures and report design—then go straight to the source with SQL (joins, CTEs, window functions) and Python to clean, transform, and analyze.
At DeltaX, I partnered directly with clients to define the KPIs that mattered and tracked product metrics like DAU, MAU, installs, and retention. I integrated and analyzed datasets across logistics, marketing, and user-behavior domains, connecting them to Power BI for real-time insight using Firebase and Mixpanel.
What sets me apart is a hard-science foundation: I bring an MSc in Geophysics (University of Aberdeen) and a Postgraduate Diploma in Data Mining, plus experience processing large, noisy, multi-dimensional datasets. I value clear communication with the people who act on the data, and I’m comfortable working remote-native and across multicultural teams.
