AI SYSTEMS ARCHITECT

I am the technology partner for companies and agencies that want to scale without multiplying costs: I build the systems that win clients, handle calls and messages, and the internal software you need that does not exist. And I review the security of what you already built with AI.

Fixed prices in writing before we start. You get me directly, in English or Spanish.

BUILDING A BUSINESS WITH AI

Thinking about starting your own business with artificial intelligence?

Every week I run a live session to build it with you: your niche, your site and your agents. It is called Sold and Scale, the membership of Sole Hand, which is my own brand. Runs in Spanish.

See how it works (in Spanish)

Expensive people doing work that belongs to a system. 

In almost every business I see there are people hunting for clients one by one, copying data between tools, and answering the same question twenty times a day. That is not a people problem: the system is missing. And if you also shipped something fast with AI, it is probably live with exposed keys or broken permissions that nobody knows about.

Manual prospecting

Finding, qualifying and writing one by one, leaving no trace

Enquiries that slip away

After-hours calls, unanswered messages, bookings that never land

Processes living in spreadsheets

Data copied by hand between tools that do not talk to each other

Five systems that do the work you still do by hand. 

PROSPECTING AND SOCIAL

Stop chasing clients: the system brings them to you qualified

In plain words: a program finds who fits your business, studies them, and writes a message meant for them.

  • Automatic search and qualification of potential clients
  • Messages written one by one with each company’s real data
  • Follow-up so nobody slips through
  • Your social channels run with judgment, not templates

tailored to your process

MARKETING AGENCIES

Your margin goes to the team doing internal work

In plain words: I automate your agency’s internal processes so your people’s hours go into what actually bills.

  • Winning and prospecting new accounts
  • Commercial follow-up through to closing
  • Asset production with generative AI
  • Client reports that write themselves

tailored

INTERNAL SOFTWARE

The tool you need does not exist, so I build it for you

In plain words: a small application built for your process, instead of paying for a subscription that almost fits.

  • Dashboards with your real data
  • Internal tools shaped around how you work
  • Integration with what you already use
  • Delivered working and explained

quoted after the call

AI-HANDLED ENQUIRIES

In progress

Nobody answers the phone at nine at night. An agent does

In plain words: a voice that takes the call, answers the usual questions, and puts the booking straight in your calendar.

  • After-hours call handling
  • Answers to the questions that repeat every day
  • Booking straight into your calendar
  • Handover to a person when the conversation calls for it

SECURITY AUDIT

You built your app with AI and nobody checked if it is safe

In plain words: I find the security holes in your website or app and tell you how to close them.

  • Secrets, access control and authentication
  • Supabase RLS, input validation and headers
  • Full OWASP checklist
  • Actionable report, explained in plain language

Hire one piece or the whole system. Everything ships working, documented and explained.

From the first call to delivery. 

01

30-min call

You tell me which process is eating your hours. I tell you what I would automate first and whether it is truly worth it.

02

Fixed-price proposal

Scope, timeline and price in writing before we start. You know exactly which system you get and what it will do for you.

03

Build, delivery and training

I build the automation on top of your tools, hand it over working, and train your team to run it without me.

Concrete results, explained clearly. 

01.A clear, actionable report.Every finding with its severity, its impact and the concrete fix. No generic PDF you cannot act on.
02.I run my systems before selling them.My own operations centre and my lead generation run on exactly what I build for you. If it is not good enough for me, I do not offer it.
03.I already do this for a whole agency.I build the AI agent layer for a full stack marketing agency: prospecting, outreach, closing and asset production. The case, with its name and figures, is below in the success cases.
04.Fixed, public pricing.You see it on the site and the proposal comes with a fixed price. No surprises, no "contact us for a quote".

A person used to do this. The hours no longer eaten by repetitive work were not cut: the team now spends them on what a machine cannot do.

MARKETING AGENCY

AI agents forCesea Agenc.ia.

Cesea Agenc.ia is a full stack marketing agency. I build their AI agent layer: finding potential clients, qualifying them, running commercial follow-up and producing assets. Their model is hybrid, senior people working alongside agents 24/7, and the agent side is mine.

System in production since late July 2026. I publish the process time, which is measurable from day one, and not cumulative outcome figures, which mean nothing after a week.

PRODUCT · SOCIAL NETWORK

Security and agents forBalority.

Balority is a startup-ecosystem social network connecting founders, investors, mentors and talent. I reviewed its app-level security using the OWASP methodology and found 29 issues to fix, five of them high severity. Then I built an internal AI agent flow that finds the most compatible people inside the network and connects them to each other, with nobody doing it by hand.

What I have trained in. 

Ten certifications from Anthropic Academy, the official training from the people who make Claude. Tap one to see what it covers.

ANTHROPIC ACADEMY · 10 CERTIFICATIONS

Building software since I was 14. 

And before this I worked inside a hospital. I was a nursing assistant, a diagnostic imaging technician and a radiotherapy and dosimetry technician. I know what it is like for the phone to ring while a patient is in front of you. Today I build AI agents and automations for companies across very different sectors, plus my own operations centre, which is how I win and manage my clients.

No university degree, no big logo behind me. I come from working the shift, and from building things and breaking them to understand how they break. That is why what I sell you runs in my own company first, and why I review the security of what I build: I know exactly where it breaks.

Frequently asked questions. 

It is a technical review of the application layer of your web or app: the code, authentication and access control, keys and secrets, the database (for example Supabase RLS policies), input validation and security headers. I follow the OWASP checklist, the industry reference, and you get a report with every finding ranked by severity plus the concrete fix for each one. It is not a penetration test and not a compliance certification: it is the review an AI-built app needs before facing real users. The three tiers, with public pricing and turnaround, live on the service page.

One process of your business automated end to end, working and documented. We pick the process together (finding and qualifying leads, commercial follow-up, handling enquiries, management reporting, or an integration with your tools), I build it with n8n and Claude on top of what you already use, and I hand it over with training for your team. A sprint takes 3-4 weeks. The price depends on the process, so it goes in the proposal, fixed in writing after the call; if you need several connected processes or want what I delivered to keep growing month by month, there is a formula for that too.

Yes. I build the AI agent layer for a full stack marketing agency, and the success-cases section has the case with its name, logo and figures. I also run the same stack in my own operation: my operations centre and my lead generation run on these tools every day.

Not yet. The architecture is decided (telephony inside the European Union, with voice and booking integrated) and a first deployment is under way, but I do not sell it as available until there is a demo you can actually listen to. When there is, it goes on this page. I would rather tell you this than sell you something I cannot show you.

No. The five services work in any business with repetitive processes: a restaurant, an agency, an accountancy. Each one is built around how you actually work. The exception is diagnostic imaging, radiotherapy and medical physics: I worked in that field as a technician, so there the solution is already built and has its own name, Kórtex, and we do not start from scratch.

Read access to the repository (or a ZIP of the code) and the app URL. If there is a database, the schema and its policies. That is enough for the Express.

Mostly what AI tools produce: Next.js and React, Supabase, Node, REST APIs, deployments on Vercel and similar. If your stack is different, ask me and I will tell you honestly whether I am a fit.

Your code never leaves my machine, I do not share it, and I delete it when the project closes. If you want an NDA, we sign it before you show me anything.

In Express and Full you get the report with the concrete fix for every finding. In Hardening I implement them myself as Pull Requests.

Before it goes to production with real users, and always when it touches payments or personal data. If it is already live and nobody has ever reviewed it, as soon as possible.

An audit, between 1-2 and 8-10 business days depending on the tier. Automation runs in 3-4 week sprints.
