Services
Four ways I can help, each with a fixed price agreed before we start. Pick the one closest to your problem, or book a call and we work it out together.
Book a free call- 01
Business websites
From€1,5002–3 weeks
A fast website, in one or two languages, that shows up on Google and turns visitors into calls, bookings or sign-ups. You can change the texts and photos yourself.
- 02
Booking & payment apps
From€4,0004–8 weeks
Customers book and pay online and get a private area of their own. You run everything from one panel, and confirmations and reminders go out by email and text message on their own.
- 03
AI for your business
From€3,500First version in 2 weeks
An assistant that answers your customers, a phone agent that takes calls, search across your own documents, or a tool that pulls data out of forms and PDFs. Tested on real examples before your customers use it.
- 04
Code audit & rescue
Fixed price€6501 week
An app or website someone else built, or one made with AI, that keeps breaking? In one week I review it and give you a clear written report: what is wrong, what to fix first and what it will cost.
Ongoing work and maintenance from €45/hour or a monthly plan. Prices exclude VAT.
How we work
From call to launch
- 01
Free call
30 minutes to understand what you need and tell you honestly whether I am the right person for it.
- 02
Fixed-price proposal
What I will build, the price and the dates, in writing within 48 hours. No surprises later.
- 03
A demo every week
Every week you see and try the real thing, not a status report.
- 04
Launch + 30 days
I put it online, hand you every access and fix any problem for 30 days at no cost.
FAQ
Before you ask
Do I need to know anything technical?
No. I explain every decision in plain words, you approve what matters, and you get something that works, not a pile of code.
Do you work with clients outside Spain?
Yes. I work remotely in English or Spanish, and my hours overlap with all of Europe and with US mornings. Calls and demos happen on Google Meet or Zoom.
Who owns the website or app?
You do. The code, the accounts and the domain are in your name from day one, and you get everything when the project ends.
How do payments work?
Fixed-price projects are paid in two parts: 40% to start and 60% on delivery. Larger projects are split into stages you approve one by one.
Can you take over a project someone else started?
Yes. That is what the code audit is for: in one week you know what state it is in, what to fix first and what it will cost.
Do you sign a confidentiality agreement (NDA)?
Of course. Send it before the first call if you need to share details.
What happens after launch?
Problems are fixed free for 30 days. After that I can keep it running with a monthly plan, or hand it to your team with clear documentation.
