About

About me

I am a Senior Data Analyst and Market Research Specialist with 9+ years of experience managing end-to-end survey data processing and analysis for large-scale, multi-market studies.

My work focuses on transforming complex research datasets into reliable, decision-ready outputs. From data cleaning, validation and cross-tabulation to Excel/VBA automation and Power BI dashboards, I combine analytical thinking with a disciplined approach to quality control and clear communication with stakeholders.

Alongside client work I build the tools my team uses: Excel and PowerPoint macros, Python apps that turn crosstabs into decks and check decks against their source data, an AI-assisted open-end coding tool, and a full web platform that builds websites for small businesses.
