Taking new projects
Niterói, BR · 08:00 UTC−3
Independent web engineer. Webflow and WordPress builds, technical SEO, security and privacy. Since 2013.
I build sites that load fast.rank on Google.don’t get hacked.your team can edit.
§01 — The problem
Most websites look fine and fail quietly: slow on a phone, invisible to Google, one outdated plugin away from a breach. I work on what’s underneath, and I prove it with numbers, not adjectives.
§02 — Services
Builds and rebuilds with a class system the next person can actually read.
Over a decade and 100+ sites, in whichever builder you already pay for.
The part of SEO that is engineering, not content calendars.
Hardening, cleanup, and GDPR/LGPD consent that actually blocks scripts.
Not sure which one you need?

A screenshot of a homepage proves nothing. These are the results the client was actually paying for.
B2B intelligence platform · own project · design to launch
A premium digital presence aimed at international oil and gas suppliers entering Brazil: tender intelligence, local commercial support, an interactive market map. Built to be read by procurement teams on bad hotel Wi-Fi, which set the performance budget before a single pixel was drawn.

E-commerce launch and operations · site, payments, marketplaces
A European manufacturer wanted to sell in Brazil and had no local infrastructure. I set up the store, the payment and shipping rails, the marketplace channels, and then ran the operation: catalogue, pricing, stock, orders, customer response.

Platform migration and SEO foundation · ongoing engagement
A full content migration off Webflow with the SEO setup rebuilt properly on the other side: URL mapping, redirects, metadata, schema, speed. The client kept me on after delivery for work they thought of later, which is the part of a migration that tells you it went well.

Builder migration on a live, ranking site
Rebuilding a site's entire page-building layer without losing the positions it took years to earn. Markup parity checked page by page, heading structure preserved, schema re-emitted, Core Web Vitals measured before and after so the improvement was a number rather than an opinion.

GDPR and LGPD technical implementation
Most cookie banners are decoration, because the tracking already fired before anyone clicked. I scan what loads before consent, then rebuild the gate so nothing runs until it is allowed: Consent Mode v2, granular categories, refusal as easy as acceptance, consent records stored, and the documentation your lawyer needs to sign off.

My own multi-channel store · 8 years, 2017 to 2025
Before I optimised other people's stores I ran one. Site plus marketplaces, with an automated routine checking 191 listings a day against the supplier's API for price and stock drift. It is why I talk about margin, stock and response time instead of just conversion rate.

“He worked very quickly, went above and beyond expectations, and was proactive in fixing and improving any issues that came up.”
★★★★★ 5.0
“Another designer had created the site but there were small fixes that we needed, and the designer wasn’t available. I found Rafael and he jumped in right away.”
§06 — About
Before I built websites I wrote technical bids at GE Aerospace, then coordinated accounts at Expro and Siemens Energy: nine years of scoping work precisely, in English, where an unclear assumption costs real money. That is still how I run a project.
Then eight years running my own e-commerce operation, and over a decade building and maintaining sites as owner of Niterói Web Design. So when we talk about your site, I am thinking about margin, stock, response time and what a lead is worth, not only the layout.
Everything I build is delivered in your accounts: your host, your domain, your Webflow workspace. No lock-in, and documentation you can hand to the next person.

§07 — Method
Step one and step four are the same tests. You get a before and an after, not an assurance.
Lighthouse and field vitals, a full crawl, response headers, plugin and user inventory, analytics and consent state. Written down before anything is touched.
What I will do, what I will not, what it costs and what I need from you. Fixed and in writing. Surprises are a planning failure, not a line item.
In your accounts and the platform you already use. Staged first, reviewed by you, released with redirects and monitoring ready.
The step-one tests, run again, side by side. If a number did not move, I say so and we look at why.
Admin access, documentation, and a recorded walkthrough of what changed. You should be able to replace me without pain.
§08 — Contact
Give me the URL and one sentence on what is going wrong: slow, not ranking, hacked, unmaintainable, or just old. You get a plain diagnosis and a suggested next step, not a brochure.
