Nigeria
Message

At Cardtonic, I lead a team of 17 QA Analysts and oversee audits across operational processes and financial transactions. I’ve helped improve process accuracy by 35% and reduce operational errors by 25%.

As a Senior Quality Assurance Associate at Cardtonic, I verified high-volume transactions and maintained a 99%+ accuracy rate. I investigated recurring defects and implemented corrective actions that reduced repeat defects by 30%.

I also investigated escalated customer complaints, identifying root causes and supporting process changes that improved average issue resolution time by 40%. I worked with Product, Operations, and Customer Support to improve workflows and service standards.

Earlier, as a Client Relations Officer (Internship) at Vafiero International, I managed client interactions and maintained an accurate Excel database. I’m Lean Six Sigma Green Belt certified and use data analysis, audits, and reporting to support quality and continuous improvement.
