What I'm looking for

I seek roles where I can design scalable cloud and payment systems, lead DevOps/CI-CD automation, mentor engineers, and align technical solutions with business outcomes in a collaborative environment.

I am a Full-Stack Developer and DevOps Engineer with four years building and operating enterprise-grade monolithic and cloud-native systems, including payment processing for BankservAfrica and live production applications across diverse stacks.

I design TypeScript Node.js backends, React component libraries, and CI/CD pipelines while managing Kubernetes clusters, Jenkins automation, and database infrastructure to improve reliability and deployment velocity.

I mentor junior developers, automate business processes like billing and reporting, and continuously upskill—holding a BCom in Business Information Systems and a BSc Honours in IT while earning certifications in Docker, Kubernetes, Go, and React.
