Philip Kantewa

I’m an Honours graduate in Computer Science who ships production software end-to-end—full-stack web apps, AI agent systems, ERP customization, and workflow automation. I move fast from idea to a live, working product and own it through deployment and iteration.

In freelance work (2024–present), I build and extend agentic developer tooling in Claude Code and Codex—authoring custom skills, hooks, and sub-agents, plus developing MCP servers that expose tools and data sources into agentic loops (including Supabase and Gmail/Drive/Calendar). I also built and deployed Keeper, a proactive personal AI agent with Telegram + web surfaces, generative UI, live presence via SSE, full-text-search memory, and nightly self-reflection.

I’ve shipped end-to-end products and integrations: an iOS app rebuilt as a full-stack web application (React + Supabase), a Namibian egg ordering/delivery/finance platform using secure Supabase RPCs, and a full payroll and accounting system with shift scheduling, SSC/tax calculations, ABSA bank-export, and AR/AP invoicing. I’m comfortable working across systems (Linux/Windows, Active Directory, LAN/WAN) and I enjoy turning real workflows into autonomous pipelines with AI agents and browser automation.
