What I do

  • AI Content Add-ons — Every blog post becomes audio, AI-summarized, LLM-ready, and search-optimized — automatically. Zero extra work for your writers. Works with any Sanity-powered site.
  • CMS Migration — Migrate your WordPress, Joomla, or Drupal site to a modern CMS architecture. Faster performance, zero plugin bloat, a CMS editors love, and AI-ready content out of the box.
  • MCP Server — Make your product accessible to AI agents. I build and host an MCP server that's global, fast, and zero-maintenance. Your customers' AI can query data, trigger actions, and get answers from your product without a human in the loop.
  • Maintenance Retainer — Never tell a client 'our developer is on vacation.' I handle uptime, security patches, dependency updates, and emergency fixes — same-day. White-label, invisible, reliable. Three tiers so you only pay for what you need.
  • White-Label Technical Partner — You focus on closing the deal. I build the site — invisible under your brand. Astro + Sanity stack means a site that loads instantly, editors love, and never needs a plugin update at 2 AM. Fixed scope, fixed price, no surprises. Your client never knows I exist.
