About

I don't just write code. I design, build and operate platforms that solve real business problems.

As CTO and co-founder of Paresi, ESG and sustainability platform, I've experienced the entire journey of building and scaling a SaaS product. I value lean processes, phased delivery and direct communication.

Common questions

How do I make my website appear in ChatGPT and AI search answers?

AI assistants favour sites with structured data (FAQ, Organization and Service schema), clear factual content and verifiable information. I implement this full stack — the same techniques used on this very site — so your business gets cited when customers ask AI for recommendations.

What does an AI integration project cost?

It depends on scope. A smart auto-reply using your real business data starts smaller than a full analytics layer. After a free discovery call I send a fixed-price proposal split into phases, so you always know the cost before committing.

Can you help my business reach Chinese customers?

Yes. I build Mandarin landing pages with WeChat integration and Baidu indexing — live example running for a London student accommodation business capturing Chinese students directly to the manager's WeChat.

Do you work with UK businesses remotely?

Yes — most of my clients are in London. I work remotely from Brazil in a UK-friendly timezone, with communication in English via email, WhatsApp or video calls, and invoicing through my company ALIW LTD.

What technologies do you work with?

React, Next.js, Node.js, SQL databases, WordPress and progressive web apps, plus integrations with Stripe, Google Analytics, Search Console and AI APIs. I choose the stack that fits your project, not the other way round.
