Message

At Visa Inc. (Open VisaNet Platform), I built and am enhancing ARTe, an AI-powered self-healing platform that monitors and remediates incidents across Kubernetes environments. It reduced manual intervention for recurring incidents by more than 70% and improved MTTR by 20%.

I'm also creating and maintaining Jenkins CI/CD pipelines for OVN release automation across AWS and Visa's private cloud. I upgraded the Service Image Resolution Platform Admin Console, eliminating manual image selection and reducing production release preparation time by 80%.

At Visa Europe, I led the end-to-end deployment and validation of the Paris 2024 Olympics VISAGO app, from development through production. I also built and maintained CI/CD pipelines and deployed containerized applications using Docker and Kubernetes.

Earlier, I worked across cloud infrastructure, DevOps, and software development at Visa Inc. (Currency Cloud), ThreatSpanCybersecurity, Tek Experts | Microsoft Leap, MOBicure Nigeria, and Stetis Connected Business Solutions. My work has included Azure customer migrations, AWS infrastructure, cybersecurity monitoring, and web applications.
