What I'm looking for

I'm looking to lead secure, scalable fintech and enterprise technology initiatives spanning backend engineering, cloud infrastructure, DevSecOps, compliance, and application security.

I've built and deployed fintech platforms including SwitchGate-Core, Giddy Enterprise Platform, PropertyBridge, and FXSwap at Numbers Systems Limited using Node.js, NestJS, TypeScript, and PostgreSQL.

As a hands-on CTO and CIO, I lead cloud, DevOps, and DevSecOps strategy across AWS, DigitalOcean, Google Cloud Platform, and Cloudflare. I design high-availability infrastructure, secure CI/CD pipelines, infrastructure automation, and financial-grade REST APIs using JWT/OAuth authentication.

I've led internal security audits, VAPT engagements, incident response, system hardening, and remediation for fintech and enterprise systems. My work includes real-time monitoring and threat detection with Wazuh, Prometheus, Grafana, and Suricata.

Across HuiosPay and Waila Microfinance Bank, I've supported secure digital banking operations, payment integrations, fraud detection, compliance controls, and infrastructure modernization aligned with PCI-DSS, NDPR, GDPR, and ISO 27001.
