Full-Stack AI Engineer building AI Agents & MCP Servers
I'm Matthew Groff, Principal AI Engineer and AI Capability Lead at Umbrage, part of Bain & Company. Based in Orlando, FL, I ship AI agents and MCP servers that automate business operations with AI-enabled workflows. I turn AI concepts into measurable outcomes, cutting processes from months to minutes. I recently published my first eBook “Build Your First MCP Server” and share insights on AI engineering and web technologies through this development blog.
Office Hours: I hold monthly sessions to help teams tackle AI engineering challenges. Book a 30-minute session to discuss your AI Product, MCP Servers, Web Dev, Systematically improving your app with Evals, or whatever strikes your fancy. These times are odd because it's weekends and before and after my day job.
