What I'm looking for

I'm looking to build scalable data systems, analytical models, and dashboards that improve data integrity, uncover anomalies, and support high-impact business decisions.

At Rhythex Consulting Limited, I work with IT Audit and Revenue Assurance teams across GT Bank, Keystone Bank, and Interswitch to improve data integrity, detect anomalies, and support transaction compliance.

I extract, validate, and model enterprise data with SQL, automate transactional-audit reconciliation using ACL, and create executive reports that drive resolution of data discrepancies.

I build data systems that turn high-volume, complex data into reliable, decision-ready insights. My work spans data extraction, modeling, analytics, pipelines, and dashboards using Python, SQL, and Power BI.

I’ve also built machine-learning models with over 87% accuracy at Hamoye.com and teach data analysis, programming, and foundational coding.
