About Me

Data tells a story.
I make it unforgettable.

I'm Mansur Adeola, a data analyst based in Lagos, Nigeria, with a multidisciplinary background spanning administrative operations, sales analytics, and client-facing data delivery. I founded PrimeInt Analytics to bring structured, insight-driven thinking to small businesses that often lack access to professional data infrastructure.

My approach is end-to-end: from database design and SQL querying through to visual storytelling with Power BI and Tableau. I don't just produce reports — I build systems that help businesses understand their own data in real time.

I hold certifications from Cisco, ALX Africa, and Udemy, and I'm currently completing a B.Sc. in Criminology & Security Studies at the National Open University of Nigeria — a discipline that sharpens my eye for patterns, anomalies, and risk.
