I build AI systems that ship.
AI engineer and solo founder replacing manual fiscal and accounting work with production-grade agent systems. Shipped a 43-tool MCP server, multi-tier Claude orchestration, Langfuse end-to-end observability, and HITL reviewer surfaces — all from zero in TypeScript. Currently building DISAI_Conta, an AI-native fiscal compliance platform for Mexican SMEs. Open to senior AI engineering roles and high-leverage consulting engagements.

About Me
Background
My path to AI engineering wasn't conventional. That's the point.
I started in graphic design and tattoo artistry, where I learned that precision and intentionality aren't optional. Then I spent years writing deep technical analysis: 20+ research reports on decentralized protocol architecture, on-chain data patterns, and economic system design. That work trained me to read complex systems, find failure modes, and communicate findings clearly.
When I discovered LLMs, MCP, and agentic systems, I stopped analyzing other people's infrastructure and started building my own.
I'm Mexican, I operate globally, I speak both En and Es.
Current Focus
Today I specialize in production AI systems engineering. Specifically:
- Custom MCP server design (tools, resources, prompts, elicitations, tasks, MCP-UI mini-apps) with SSE and HTTP Streamable transport
- 3-tier agentic orchestration: lightweight router → domain-specialized agents with native tool_use → Expert Registry with scoped allowlists and live MCP resource injection
- Langfuse observability: every LLM call, tool invocation, model selection, token cost, and streaming event tracked end-to-end with cost attribution per session
- HITL reviewer surfaces: compliance dashboard and EFOS monitor as Next.js interfaces with one-click approval flows wired directly into the agent pipeline
- LLM system testing: 3,960+ passing tests, 91%+ coverage on a solo-built TypeScript codebase
- Full deployment stack: Docker, Railway, CI/CD, rate limiting, security headers, RLS, observability
I currently operate as an independent AI engineer, building DISAI_Conta (a production fiscal AI platform) and taking on select consulting engagements for teams that need real AI infrastructure, not demos.

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.
Let's work together
Whether you're building an AI-native product and need a senior engineer, or you're a business that needs real AI infrastructure, not demos, not wrappers. I'm open to the right conversations.
