South Africa

Message

At Dijkstrack, I lead research and development into AI-assisted software development. I build evaluation tools and automated pipelines for repository analysis, commit evaluation, and comparison of AI-generated code.

I also design comparative experiments between standard AI generation and specification-augmented workflows, and research how specification-driven development affects AI agent performance.

At ACCSO, I designed REST APIs, integrated internal and third-party systems, and developed enterprise backend services with Java and Spring Boot. I also created an agricultural blockchain MVP for traceability and data integrity using Hyperledger technologies.

Earlier, I developed government web forms at Interfront SOC (SARS) and backend systems at CompuGroup Medical. My experience also includes full-stack development, production support, and Java applications across several organizations.
