About Me

The Analyst Behind
the Numbers

I'm a results-driven Data Analyst transitioning from 7 years of frontline sales into business intelligence — bringing a rare commercial perspective that most analysts lack.

My edge: I frame the business question first, then touch the data. I'm not just reporting numbers — I'm diagnosing what drives them. Whether that's uncovering revenue leakage, modelling discount policy impact, or flagging customer concentration risk.

Skilled in SQL, Advanced Excel, Power BI and Power Pivot with a track record of transforming raw, messy datasets into structured models. Currently expanding into Python (Pandas, EDA, data wrangling).

BSc Microbiology at Olabisi Onabanjo University (2021–2025) — a scientific foundation that trained the systematic, hypothesis-first analytical mindset I bring to every project.
