I’m an Integration Engineer with over 5 years of hands-on experience delivering mission-critical enterprise API integrations and middleware engineering in high-volume financial environments. I specialize in designing, configuring, securing, and supporting IBM DataPower Gateway services, including MPGW, WSP, and API Gateway.

In my roles, I focus on secure authentication and authorization for enterprise integrations using OAuth, JWT, AAA policies, SSL/TLS, mTLS, and WS-Security. I build and mediate REST, SOAP, XML, JSON, and XSLT-based flows, and I manage asynchronous messaging using IBM MQ and reliable integration patterns across distributed systems.

I’ve delivered integrations across the SADC region, including work supporting the Eswatini National Payment Switch (NPS) and Identity Verification (ID&V) services. I also reduce production risk through payload validation, request transformation, response mapping, certificate management, and troubleshooting performance, connectivity, and production incidents using log analysis and root cause investigation.

I’m comfortable owning integration lifecycle activities such as deployment support, SIT/UAT testing, and post-production monitoring. I also bring an AI-assisted development mindset—using tools like ChatGPT and Codex AI—to accelerate architecture, solution design, debugging, and technical documentation while maintaining production-quality standards.
