Hi, I'm Carlos Jimenez 👋

Forward-Deployed / Applied AI Engineer · Founder @ R21 Digital 🚀

I build and ship production agentic systems — multi-model LLM orchestration, MCP servers, and full-stack AI products.

AI Agents · MCP / Tool-Calling · Multi-Model LLM Routing · Full-Stack (Next.js) · GEO / AI-Search

🛰️ Live SaaS shipped · 📱 Native iOS app on the App Store · 🤖 Self-hosted multi-agent fleet in production · 🏥 15+ yrs enterprise IT (HIPAA)

🚀 About Me

  • 🤖 I run a self-hosted fleet of autonomous agents, each on its own least-privilege identity, with routing across Claude, GPT, Gemini, and Groq — chosen per task for cost and latency, with observability so a failed step degrades safely.
  • 🔌 I write the MCP servers and tools that connect those agents to real systems, plus RAG + memory on Pinecone and Mem0.
  • 🧠 Full-stack, end-to-end: Next.js + Supabase + Vercel web, Flutter + native iOS (shipped to the App Store), automation on Make.com / n8n.
  • 🏥 15+ years of enterprise IT underneath — including HIPAA-regulated systems run under change control — so I design AI that survives audit and real load, not just a demo.
  • 🏢 Founder-operator @ R21 Digital (Mesa, AZ) — I lead a distributed team delivering web, automation, and AI for businesses across the US, PR, and Latin America.
  • 🇺🇸 US Citizen · based in Arizona · open to Forward-Deployed / Applied-AI / Solutions Engineering roles (remote).
  • 📫 cjimenez@r21digital.com

By the numbers — 1 open-source MCP server published · self-hosted agent fleet in production · 1 live SaaS · 1 iOS app on the App Store · client sites live across the US, PR & Latin America

🔎 Selected Work

  • practice-fusion-mcp — open-source, FHIR-first, read-only MCP server for the Practice Fusion EHR (TypeScript, SMART backend-services auth, audit-logged, fully tested). One piece of the self-hosted multi-agent gateway + multi-model routing I run behind client work.
  • fantasytabletophelper.com — a live product I built and shipped end-to-end (Next.js, AI-assisted tabletop gameplay tooling).
  • GEO / AI-search optimization — I deploy and tune AI-search visibility (schema, llms.txt, citability, AI-crawler access) across production client sites.
  • Native mobile — Flutter + native iOS, shipped and live on the App Store.
