Senior Business Analyst turning product and unit-economics data into revenue levers in cross-border fintech.
NigeriaWhat I'm looking for
I’m a senior product, growth, and business analyst who turns user, transaction, and revenue data into commercial decisions in a B2B cross-border fintech environment. I combine SQL, Python, BI, cohort analysis, and pricing logic to improve trust in core metrics and translate ambiguous questions into measurable actions.
In my recent role, I build and maintain metric-first dashboards and canonical SQL models (BigQuery + dbt), so Sales, Customer Success, and trade teams can act on corridor performance, client health, conversion, and unit economics. I also run rigorous pricing and growth experimentation—designing hypotheses, selecting statistical tests, and interpreting results—while keeping experiment decisions grounded in sustainable unit economics.
Beyond fintech, I’ve delivered decision-ready analytics in market intelligence and downstream oil & gas—aggregating fragmented data into reliable repositories, forecasting demand with statistical rigor, and optimizing pricing margins using regression-based models. My approach is consistent: own the metrics, prove impact with analysis, and communicate clearly through executive decks and strategic briefs.
