# AI agents wired into the systems your clients already run.

I design and build agents that query the PMS, the CRM or the ERP, including the ones that only speak SOAP, and I take them to production with evals and cost control. I work with agencies and product teams, embedded in your team or under your brand.

## Who I work with

* ### Agencies and consultancies  
You sell an AI project and need someone to build it. I work under your brand, in your tools and under NDA. Your client sees your team.  
[How I work with agencies](/en/agencies/)
* ### Startups and product teams  
There is an AI feature on your roadmap and nobody free to build it. I join for a few weeks, or a few days a week, and we ship it with your team.
* ### Tech leads at established companies  
You have internal processes an agent could handle and systems nobody wants to touch. I take care of the analysis, the integration and the rollout.

Run a small business and want to automate tasks or get a website that brings you customers? I work with small businesses too.[Services for businesses](/en/business/)

## Services

Every project starts with a call and a proposal within 48 hours: scope, timeline and a fixed price.

* ### AI agents and orchestration  
Tool-using agents, RAG over your documentation and multi-step flows with LangGraph. Each one ships with an eval suite, so you know it answers well before real users see it.  
2 to 4-week sprint, fixed price
* ### Product engineer on your team  
I work in your repo, your Jira and your Slack. I have a say in what to build and in what order, and then I build it.  
Days per week or monthly retainer
* ### White-label work for agencies  
I build the project you sell, under your brand and under NDA. If needed, I join meetings with your client as part of your team.  
Per project
* ### AI project audit  
Your agent makes things up, is slow or costs too much. In one week I measure where it fails and hand you a plan to fix it.  
1 week, fixed price

## What I bring

* ### Integration with real systems  
I've connected hotel PMSs such as Sihot, Mews, Cloudbeds and Apaleo, ERPs on Business Central, SOAP/XML services and payment gateways. That's where many agent projects get stuck.
* ### Consultancy experience  
Two years at Devoteam doing technical leadership, requirements gathering and client work on pharma, banking, energy and hospitality projects. I know how an outsourced project works from the inside.
* ### A product of my own in production  
I designed Hospitality RMS, a revenue management system for hotels, from requirements to infrastructure. It has been running at an aparthotel since March 2026.
* ### Agents you can measure  
Every agent ships with an eval suite, per-answer traces of latency, tokens and cost, and a spending cap. Before launch you know how often it gets things right and what it costs.

## How I work

1. ### Call  
30 minutes to understand the project. I tell you whether I fit.
2. ### Proposal  
Within 48 hours: scope, timeline, fixed price and what I'd leave out of the first version.
3. ### Build  
A demo every week. I work in your repository from day one.
4. ### Production  
Deployment, agent evals, monitoring and documentation for your team.
5. ### After launch  
Support, improvements or a full handover to your team, whichever you prefer.

## Work

Many of my projects are signed by the agency that hired me, so I describe them here without names.

## About me

I'm Jesús García Terrón, an independent product engineer in Valencia, Spain. I've spent five years on consulting and product projects, and now I work with agencies, startups and companies as Red Moon Consulting.

I get involved from the moment we decide what to build: the scope, what goes into the first version and how it fits with what already exists.

[More about me](/en/about/)

## Questions

How much does it cost?

It depends on the scope. After the call I send you a fixed-price proposal within 48 hours. If I'm embedded in your team, I bill by the day or with a monthly retainer.

Do you sign NDAs and work white-label?

Yes. I sign the NDA before seeing the project, and I never mention an agency's clients without permission.

Who owns the code?

You or your client do, from the first commit. I work in your repository and leave documentation so anyone can pick it up.

How do you invoice?

As a self-employed professional registered in Spain. If your company is in another country, we settle the details in the proposal.

Do you work in English?

Yes. Meetings, documentation and code in English or Spanish.

When can you start?

It depends on my workload at the time. I give you a specific date on the call.

## Tell me about your project

A 30-minute call, no strings attached. If I'm not the right fit, I'll tell you.
