I build AI systems that ship.
AI engineer building production-grade LLM and agent systems in TypeScript. I designed and shipped a 43-tool MCP server and a multi-tier Claude orchestration layer from zero — backed by 6,000+ tests and end-to-end observability. I build for production, not demos. Open to AI engineering roles where I can bring that to a team.

const result = await mcp.callTool(
'generar-factura', params
);
const client = new Anthropic();
const msg = await client.messages
.create({ model, tools });
About Me
Background
My path to AI engineering wasn't a straight line, and that's where the edge comes from.
I started in graphic design and tattoo work, where precision and intentionality aren't optional. Then I spent two years writing deep technical research on complex systems — protocol architecture, incentive design, market structure — which trained me to read an unfamiliar system fast, find where it breaks, and explain it clearly. When I found LLMs and the Model Context Protocol, I stopped analyzing other people's infrastructure and started building my own.
Mexican, operating globally, fully bilingual — Spanish native, English professional. EST-aligned, async by default.
What I do
I build the unglamorous parts that make AI agents trustworthy in production:
- MCP server design — full primitive set (tools, resources, prompts, elicitations, MCP-UI), SSE + HTTP Streamable transport, multi-tenant architecture.
- Multi-tier agentic orchestration — a lightweight router classifies intent, domain-scoped agents run native tool_use loops with self-correction, and an Expert Registry enforces per-domain tool allowlists with live resource injection.
- Observability & cost control — end-to-end Langfuse tracing on every LLM call, tool invocation, model choice, and token cost, with per-session attribution and failure triage without log digging.
- Human-in-the-loop surfaces — one-click approval flows wired into the agent pipeline for irreversible operations.
- Production discipline — 6,000+ tests, 91%+ coverage, CI/CD, schema validation at every boundary, conventional commits, drift guards. The hygiene that makes solo-built work safe to hand to a team.

Projects

SAT-MCP — 43-tool fiscal MCP server
A production MCP server for Mexican tax compliance (CFDI 4.0). Full primitive set plus 8 MCP-UI mini-apps for in-chat document rendering, SSE + HTTP Streamable transport, multi-tenant CSD management, 5 PAC providers behind circuit breakers, and EFOS/EDOS blacklist monitoring. 5,500+ tests, 91%+ coverage, solo-built in strict TypeScript. Private commercial product — happy to walk through the architecture and code in an interview.
Tech Stack:

DISAI_Conta — 3-tier agent system
An AI-native fiscal platform built on SAT-MCP. A Haiku router classifies ten fiscal domains in ~100ms, ten Sonnet domain agents run native tool_use loops (up to 6 iterations, parallel calls, self-correction), and an Expert Registry injects the right SAT catalog resources into context before the first call — which removes an entire class of hallucinated catalog codes without RAG query overhead. Langfuse traces everything; a HITL dashboard gates irreversible operations; streaming SSE chat built in Next.js 16.
Tech Stack:

Crypto / TradFi Analytics Terminal
A real-time analytics dashboard aggregating on-chain and traditional market feeds over dual WebSockets, with a Node.js backend, Redis caching, and graceful degradation for low-latency uptime. React + TypeScript, Dockerized, deployed on Railway/Vercel.
Tech Stack:

n8n freelancer starter
A one-click Railway template for self-hosted n8n, production-configured, built to replace the $20–30/mo Zapier/Make dependency for small teams.
Tech Stack:
Systems Analysis
Before building AI systems, I spent years producing deep technical research on complex economic and protocol systems: consensus mechanism design, cryptoeconomic incentive structures, Layer 2 scaling architectures, and on-chain market microstructure. The same pattern recognition and architectural thinking now drives how I design and reason about AI infrastructure.
Writing
I write about what I actually build: the non-obvious problems, the design decisions, and what breaks in production.
