AI engineering · Costa del Sol
AI assistants that never make up prices or availability.
I build 24/7 multilingual assistants and automations for clinics, holiday-rental managers and estate agencies, connected to the tools you already use and with a person in charge of anything important.

Your clients write when you are closed
It's 23:40 and a patient writes in German, asking to move tomorrow's appointment. By the time reception reads it the next morning, the slot is lost and the patient has booked somewhere else.
Messages out of hours
Many enquiries arrive in the evening and at weekends, when nobody is there to answer.
Many languages
Clients write in English, German, Dutch or Swedish, and not everyone on your team can reply well.
Repetitive admin
The same questions, and the same copying and pasting between tools, every single day.
What I build
24/7 assistant
Answers your clients' questions and handles bookings on your website, in their language, day and night, and hands over to your team when it matters.

Who it's for
Local businesses with a small team and a lot of client questions. These are the three I know best; if yours is different, tell me about it.
How I work, in plain words
You don't need to know how AI works to trust it with your clients. These four rules apply to everything I build.
Checked, not guessed
The assistant answers from your real information: prices, availability, opening hours. If it doesn't know, it says so and asks your team instead of inventing an answer.
A person has the last word
Routine bookings follow your real availability and rules, and your team sees every one. Prices, exceptions, refunds and any other commitment are confirmed by a person.
Your data stays in the EU, and it's yours
I host in the EU wherever possible, sign a data-processing agreement with you and hand over the code and the data. No platform you can't leave.
A clear AI notice
Every assistant tells people from its very first message that they are talking to an AI, as the law requires, and offers a way to reach a person.
How a project goes
20-minute call
You tell me how your business works and where time is lost. No preparation needed.
Diagnosis
In about a week, I map your processes and propose the few changes that will pay off first, with a fixed scope.
30-day pilot
The assistant or automation goes live on a small scale and is measured: first-response time, questions solved without your team, out-of-hours leads or bookings and hours saved.
Ongoing care
Monitoring, improvements and a monthly report, so it keeps working as your business changes.
Hi, I'm Sergio
I'm an AI engineer based in Marbella. I build assistants that answer from your real information, check anything important with a person and keep your data in the EU. You deal with me directly, from the first call to ongoing support.
More about meCommon questions
Where is my clients' data, and who can see it?
In the EU wherever possible, in systems you control. Only you, your team and I (while I maintain the assistant) can access it.
We sign a data-processing agreement that lists every provider involved, and the assistant only keeps what it needs to do its job.
Can it work on WhatsApp?
Yes, as an optional module. The main channel is your website or an app your clients install, which has no per-message costs and keeps data away from Meta.
If your clients expect WhatsApp, the same assistant connects to Meta's official API. It needs a business verification and its own number, and Meta's message fees go to your own account.
What if the AI gets something wrong?
It is built not to guess: it answers only from your information and, when it isn't sure, says it will check and passes the question to your team. Routine bookings follow your real availability and rules; prices, exceptions and other commitments are always confirmed by a person.
Before launch, and every month after, I test it against real questions and review the conversations, so problems are caught and fixed early.
How is the cost decided?
After the diagnosis you get a fixed-scope proposal: what's included, what isn't and the timeline, with a one-off setup and a monthly fee for ongoing care. No surprises later.
Variable usage, such as AI calls or WhatsApp messages, is billed to your own accounts, so you pay the real cost without a markup.
