Oluwafunmilayo Ajayi

I’m a Data Analyst with 3 years of experience in fintech transaction control, internal audit, and customer operations. I use SQL, Advanced Excel, and Power BI to clean multi-source datasets and turn them into dashboards that track revenue, risk, and performance trends.

In independent projects, I identified GHS 270K in unrecovered revenue by tracing pricing inconsistencies and channel misallocation, then produced audit-ready figures using SQL transformations. I also audited 13,698 cloud records, surfacing 3,416 security vulnerabilities and modernization debt, and delivered recommendations projected to cut total vulnerabilities by 60%.

Operationally, I analyze patterns in daily customer transaction queries, build structured interaction logs to spot recurring issues, and validate customer and financial records to keep data accurate. I’ve helped keep complaint volume below 5%, supported near-zero escalation, and improved internal audit documentation to reduce record retrieval time by an estimated 40%.

I work comfortably in remote, worldwide settings and present findings in plain language for non-technical stakeholders. My focus is consistent data quality, clear KPIs, and actionable insights that reduce risk and improve performance.
