About me

I am a South African full-stack developer and product founder building data-intensive platforms, cloud systems and applied AI tools.

I work across the complete product lifecycle—from database architecture and backend APIs to frontend interfaces, infrastructure, deployment and production operations.

My flagship product is Tenders-SA, a procurement intelligence platform that transforms fragmented South African tender and award information into structured, searchable and actionable business intelligence.
