Senior Software Engineer at CyberPro Consulting building RESTful microservices and modernizing legacy applications with ASP.NET Core.

South Africa

Message

At CyberPro Consulting, I designed RESTful microservices to automate support processes, with resilient logging and alerting. I also migrated legacy VB6 applications into modular, API-driven services using ASP.NET Core.

At CSG International, I worked on moving a telecom routing engine from a monolithic system to decoupled microservices. I exposed internal services through secure REST APIs and led CI/CD modernization for API deployments.

At Capitec Bank, I designed and integrated third-party payment APIs for funeral cover claims and collections. I also developed fault-tolerant WCF services with transaction-safe processing.

Across work at Sanlam, The Foschini Group (TFG), and City of Cape Town, I developed enterprise APIs and applications, reporting solutions, and database integrations. My experience includes .NET development, API integration, microservices, and supporting systems across finance, telecoms, retail, and government.
