about

Passionate, product-oriented data analyst who loves to work on great products and tackle difficult problems.

my vision

I want to change the way you think about data analysis. Data by itself doesn't bring any value. I use sophisticated data processing and transformation tools—combined with passion, creativity, and analytics—to tell a story with data that reveals its value and relevance. By performing data acquisition and developing user insights, I drive recommendations that can shape your product and maximize it’s value.
