What I can build for you

Four kinds of work, usually combined. You get one person who builds it and stays responsible for it.

Websites and digital platforms

Business sites, booking journeys, payments and customer portals for property, hospitality and B2B.

e.g. Huyton 220

Custom software and SaaS

Internal tools, admin systems and full web applications that replace spreadsheets and manual work.

e.g. Paresi

AI integration and AI search

Assistants that work with your own data, and a site built to be understood by ChatGPT, Claude, Perplexity and Google AI Overviews.

e.g. GSC booking assistant

Analytics and ongoing support

See who enquired, from where and through which campaign. Then keep improving the platform month after month.

e.g. GSC lead reports

Based in: Curitiba, Brazil. UK-friendly hours.

Common questions

Do you work with UK businesses remotely?

Yes. Most of my clients are in London. I work from Brazil in hours that overlap with the UK working day, with agreed milestones and regular updates by email, WhatsApp or video call.

Can you take over an existing website or application?

Yes. I start by reviewing what is there, list the technical priorities, then improve performance and security and keep developing it.

How do you price projects?

Each phase has a fixed price once the scope is clear. Ongoing support is agreed separately, as a monthly arrangement.

Can you help my business appear in AI search results?

I improve the technical foundations, structured data and content that ChatGPT, Perplexity and Google AI Overviews read. Nobody can guarantee a citation, and results depend on your market and competition.

Tell me about your project.

I reply the same day, usually within a few hours.
