What I'm looking for

I'm looking to build and lead production-grade agentic AI, SaaS, cloud, and WordPress platforms where architecture, autonomy, security, and measurable product outcomes matter.

I've led architecture for The Mail & Guardian's investigative news platform, serving 2M+ monthly users and 17M+ monthly page impressions. I built Alpha, a WordPress performance engine that reduced memory use by 22–37% and page-load times by 52–55%, and architected GCP infrastructure sustaining 99.9% uptime.

I'm also shipping Agent Builder, a WordPress plugin for autonomous AI agents with multi-agent orchestration, RAG, 140+ tools, and integrations across WhatsApp, Slack, email, Google Sheets, and MCP servers. My work spans production AI products, cloud platforms, React and Next.js applications, and high-availability systems.
