01
Budgets that spiral
You start with one number and every month brings a new extra. Without a clear written scope, the project never ends and the invoice keeps growing.

01 — The problem
A poorly planned digital project gets expensive
02
Deadlines that slip
"Two more weeks" turns into months. Meanwhile your competitors move forward and your idea loses the edge it had.
03
Technology that can't keep up
Everything worked fine until customers arrived: now the site goes down at the worst moment and every fix breaks something else.
02 — Services
I handle the technology, you run your business
I don't sell hours — I deliver finished solutions that solve a specific problem. These are the ways I can help you.
AI agents for your business
Smart assistants that serve your customers on WhatsApp or the web, reply instantly and connect to your systems: calendar, invoicing, CRM. Like a tireless employee, working 24/7.
- Handles WhatsApp, web and social chats instantly, any time
- Books, changes and reminds appointments using your real calendar
- Answers with your business data — it never makes things up
- You decide what it can do: clear permissions, everything logged
Your digital product, turnkey
From first meeting to launch: I design, build and ship your web application or platform, ready for your customers to use.
Systems built to grow
If your platform will handle lots of users or lots of data, I build it to withstand growth without crashes or surprises, from day one.
Your service, always on
I keep your platform available, fast and up to date, and ship every improvement without taking the service down.
An expert second opinion
If you already have a system and something isn't right, I review it thoroughly and tell you what to fix first and why — in language you'll understand.
Your tech lead, on demand
I help you make technology decisions: what to build, who to hire and what it should cost. Like having a CTO, without the full-time hire.
03 — Case studies
Measurable results, not promises
Real systems running today: the problem, what I built and what it achieved.
Dental clinic · AI + WhatsApp
The AI receptionist that never sleeps
A clinic was losing patients to unanswered calls and forgotten appointments. Now an AI assistant runs their WhatsApp: it replies instantly, books and reschedules using the real calendar, answers common questions and sends reminders. The team focuses on patients while the schedule fills itself.

Enterprise · Custom AI
Your whole company, one question away
A private AI assistant, trained on company knowledge and connected to its systems: sales, inventory, customers. The team asks in plain language — "how much did we sell this month?", "prep a summary of client X" — and gets answers and actions instantly, with role-based permissions and a log of every action.

Water utilities
Water meters that read themselves
A utility needed consumption data from thousands of meters without sending technicians door to door. I built the platform that receives readings instantly, flags leaks and unusual usage, and shows it all on easy-to-read dashboards.

Automation
Repetitive work, on autopilot

04 — How I work
A clear process, no surprises
From day one you know what you get, when you get it and what it costs.
We talk about your idea
30 minutes, free, no strings attached. Tell me what you need in your own words — no tech talk required. If I'm not the right fit, I'll say so and point you in the right direction.
A fixed-price proposal
You receive a clear document: what will be done, when it will be ready and what it costs, phase by phase. No fine print, no surprise invoices.
Progress every week
Every week you see your project working a little more: live demos, your feedback and adjustments along the way. You always know where things stand.
Handover & ongoing support
You get everything working, explained and in your name. If you want, I stay close for improvements and maintenance — but you never depend on me.

05 — About me
You talk directly to the person doing the work
I'm a software engineer with years of experience building systems used by thousands of people today: smart water platforms, real-time fleet tracking and automations that save hours of work every day.
My principle is simple: a project is done when it works, it's explained, and your business uses it daily. Not before, not after.
Senior experience only
Your project is nobody's training ground: the person who sells is the person who builds.
No middlemen
No account managers, no broken telephone: things get decided in one direct conversation.
Clarity first
I translate technology into business decisions: you'll always understand what's being done, why, and what you gain.
Spain · Remote
European hours, meetings when they suit you and smooth communication wherever you are.

07 — FAQ
Frequently asked questions
What if I don't know anything about technology?
Perfect — my job is to make sure you don't need to. I explain your options in plain language, recommend the most sensible one for your case and handle everything technical from start to finish.
How much does a project cost?
It depends on the size, but you always know before we start: a fixed-price proposal by phases, with an upfront payment and the rest tied to deliveries. If budget is tight, I'll propose a smaller first version that delivers value as soon as possible.
How long does it take?
A small project can be up and running in a few weeks; a large one is delivered in phases over a few months. Your proposal includes concrete dates, and you'll see real progress from week one.
Do you work with clients outside Spain?
Yes. I work remotely with clients across Europe and the Americas, in Spanish or English. With weekly progress and constant communication, distance is a non-issue.
What happens when the project ends?
Everything is left working, documented and in your name: the code and the accounts are yours. You can stay with me for maintenance and improvements, or continue with another team — no strings attached.
How does invoicing work?
Legal invoices as a registered professional in Spain, with VAT where it applies. For EU companies with an intra-community VAT number and clients outside the EU, invoices are issued without VAT under current regulations.
