I design, build, and maintain complete digital products: from first sketch to production server. I run products of my own, so I treat every project as if the business were mine.

04 Frequently asked questions
What kind of projects do you take on?
Business and product websites, online stores, APIs and system integrations, internal dashboards, and AI process automation. If your project doesn’t fit exactly, ask anyway — the first conversation costs nothing.
What does the process look like, and what does it cost?
First a call or email to understand the goal. Then a written proposal with scope, timeline, and a fixed price. Development runs in phases with visible deliveries. Price depends on scope: a landing page doesn’t cost the same as a SaaS.
Do you work remotely and in English?
Yes. I work from Alicante, Spain with remote clients, in Spanish and English.
What happens after delivery?
The project ends up documented and in your name: domain, code, and servers. I offer optional maintenance with updates, backups, and ongoing improvements.
