What I'm looking for

I want to lead cloud transformations where downtime isn’t an option—owning architecture, migrations, and production reliability with strong security. I’m excited to build multi-cloud platforms, automate operations, and deliver measurable savings and performance.

I build and migrate cloud infrastructure for banks and enterprises that can’t afford downtime. I’ve moved payment systems to Kubernetes and engineered database migrations where losing even one transaction wasn’t an option.

Across AWS, Azure, GCP, and Huawei Cloud, I lead architecture and client delivery, including incident response and production runbooks. I’ve standardized infrastructure documentation, disaster recovery playbooks, and security defaults so teams can deploy with confidence.

My work has produced measurable outcomes: I cut a startup’s AWS bill from $7K/month to $0, eliminated an EKS bill entirely by containerizing workloads into Lambda, and reduced aggregate client cloud spend by 35%. I’ve also generated $600K+ in consulting revenue through partner engagements with banks like Ghana Commercial Bank and Fidelity Bank.

From payment gateway outages handled in 18 minutes to sub-second CDC migrations (MSSQL to PostgreSQL) with zero transactions lost on cutover, I’m at my best when reliability, security, and performance all matter. I enjoy turning complex systems into repeatable platforms using Infrastructure as Code, Kubernetes, and CI/CD.
