Founding Engineer at Cudium building cross-border payment systems for wallets, transactions, and partner integrations.

At Cudium Ltd., I architect and maintain backend systems for a cross-border payment platform, covering wallet operations, transaction processing, partner integrations, and operational workflows. I also design financial workflows for deposits, withdrawals, transfers, reconciliation, and auditability.

At Rad Consulting UK, I designed event-driven services to synchronize COINS ERP, Bluestone PIM, and Algolia. Reusable adapters reduced integration complexity and accelerated new service rollout by 50%.

At Appmixer, I contributed across the SDK, Backoffice, and Core API for an enterprise workflow automation engine, delivering features, OAuth-based security enhancements, and fixes for customer-reported bugs. I also maintained and deployed services with Docker and OpenShift, using GitHub Actions for CI/CD.

Earlier, I built payment integrations with Stripe, Flutterwave, and Paystack at Digital Medium Africa, and developed websites, web apps, and a custom CMS as a freelancer. I also created a Python automation bot that reduced manual data-entry effort by 90%.
