About Me

I turn raw data
into valuable insights.

With 5+ years of experience in data analytics, I specialize in transforming complex datasets into compelling narratives that drive business decisions. I've worked with startups and enterprise teams across fintech, e-commerce, and healthcare.

My toolkit includes Excel, Python, SQL, Power BI, and Tableau — but my real superpower is asking the right questions and critical and constructive researchbefore touching a single line of code.
