A portfolio presented as an instrument. The six keys above choose the module, the LUA walks the list and the SOL opens whatever is selected. Everything the instrument’s screen shows is written out below, and all six modules are always here — including the ones that are not lit.

Porto Alegre, Brazil.
- What color should I wear today?
- Gray. The number talks louder.
- Blue. Cold enough to measure.
- Black. The screen wins in the dark.
- Will I get lucky today?
- Not luck. Sample size.
- Two out of three times.
- No. But you can test again.
- Should I send the message?
- Send it. And measure the reply.
- Send the second version.
- Send it. Tomorrow you rewrite it.
- What do my stars say?
- That they load in two seconds.
- That they align well on mobile.
- That nobody measured them, so nothing.
PROJECTS
-
CORPORATE WEBSITE + BLOG
Corporate website + blog · Graecus
A WordPress corporate website and blog on a theme built for it, hand-built, with no page builder.
OVERVIEW
A corporate website and blog for a growth consultancy: six service lines, from paid media to data engineering, under a single brand.
THE PROBLEM
Each line has its own stack — Google and Meta in media, Hubspot and RD in CRM, BigQuery and Databricks in data. Written as a column, the six become an inventory of logos and no decision.
BUILD
Each service is a card and the tools are labels inside it. A custom WordPress theme, with no page builder: PHP templates for home, services, archive, categories and articles, all on shared components.
THE BLOG
Search, category filter, thematic shortcuts and pagination, all on one article template.

CORPORATE WEBSITE
Corporate website · CMP Inox · 2024
A corporate website for a stainless steel supplier, with a catalog, technical tables and a quote form.
OVERVIEW
A stainless steel supplier, thirty years in business, that sold by phone and by referral. The site is for the buyer who already knows what they want and only need to check the alloy is there.
THE BUYER
Nobody opens a steel catalog out of curiosity. They arrive with an alloy and a gauge written down, and the hierarchy answers that: product before company, technical table before argument.
THE DECISION
No CMS. Built in Webflow on the Client-First class system, exported and served as static files, with the sitemap versioned alongside them. The chemical compositions are a file, not an image.
MEASUREMENT
GA4 on every page from the first version. The form qualifies before the contact does: company, segment and preferred channel.
PARTNERSHIP
Work made in partnership with Eduardo Braga.
-
LAW FIRM WEBSITE
Law firm website · Maiara Teixeira Advocacia
A site for a real estate and succession law practice, with booking and a light and dark theme.
OVERVIEW
A real estate and succession law practice in Cachoeirinha, Brazil. One page, everything inside.
WHO COMES LOOKING
Someone looking for a probate lawyer usually comes at a difficult time, weighing a few names and looking for whoever has done it before. The site was built to answer that.
THE DECISION
No framework and no build step: one HTML, one CSS and one JavaScript, served static. Its own form, and WhatsApp with the message pre-filled by subject.
PARTNERSHIP
Work made in partnership with Eduardo Braga.
-
LAW FIRM WEBSITE
Law firm website · Anelise Porto Advocacia
A site for a general law practice, with six areas of law and direct contact over WhatsApp.
OVERVIEW
A general law practice in Cachoeirinha, Brazil, with six areas of law on one page.
THE PROBLEM
Six areas compete for the same attention. Listing all six at equal weight helps nobody choose, and hiding any of them loses exactly the client who came in through it.
THE DECISION
The areas open in place, one at a time, and the whole page comes inside the HTML served. No framework and no build.
ONE ROUTE ONLY
No form: the whole site leads to WhatsApp, repeated in every section. The practice promises a fast answer, and that is why there is only one route.
PARTNERSHIP
Work made in partnership with Eduardo Braga.

LANDING PAGE
Landing page · Hélder Rodrigues · 2026
A landing page for a personal trainer, designed in Figma and built in React.
OVERVIEW
A landing page for a personal trainer, built in React from a design made in Figma.
WHAT IS BEING SOLD
You cannot try personal training before buying it. What the client judges is the method.
THE DECISION
Assessment, plan, monitoring and adjustment become numbered steps, beside a panel of numbers. React 19 with Vite and Tailwind, in thirteen components, one of them dedicated to the meta tags.
PARTNERSHIP
Work made in partnership with Eduardo Braga.

INTERACTIVE WEBSITE
Interactive website
A portfolio conceived as an instrument. Six keys reach the modules, the LUA walks the content and the SOL opens what is selected.
OVERVIEW
A portfolio that is an instrument: one screen, no scroll and no routes, with the content living on the device display itself.
THE REASON
Strategy, messaging, design, front-end and analytics in one person become a list of job titles when written as a column. Here they are the thing the visitor operates before opening any case.
BUILD
Three.js draws the object. The content lives in one file and is read twice — by the Screen and by an HTML mirror, pre-rendered at build time. A crawler used to read 465 characters; it now reads 5,675.
REFERENCES
Celestial maps, esoteric engravings, analog analog mechanisms and monochrome terminals. The reference object is an Old Blood Noise Endeavors pedal.

ART GALLERY
Art gallery
A gallery in progress, gathering posters, compositions and visual studies into a single archive.
IN PROGRESS
A gallery in progress, gathering posters, compositions and visual studies into a single archive. The first pieces are here; the archive is growing.

-
THE PATH
ORIGIN

EDITORIAL

EXECUTION
Marketing, landing pages, UX/UI and front-end bring strategy and execution closer together.

CRITERIA
The data decides. Delight counts too.
-
01
WHY
Evidence and observed behavior set the starting point. The solution has to improve what matters without giving up clarity, personality and the pleasure of using
-
02
WHY
Choosing the format too early can produce a good solution to the wrong question.
-
03
WHY
Messaging, interface and acquisition are one system. The promise made in the ad has to stay true on the landing page and in the product.
-
04
WHY
An experiment exists to reduce uncertainty. The aim is not to prove an idea was right, but to produce evidence for deciding the next step.
-
05
WHY
A metric only matters when it changes a decision. Before measuring, you have to define what would make the work carry on, change direction or stop.
