F&A Móveis

A furniture catalogue where every measurement is real, and every sale ends in WhatsApp

A furniture shop's whole online catalogue, with real prices and real centimetre measurements on every piece — no cart, just a WhatsApp message pre-filled with the exact product, sent straight to Fátima, the owner.

Oishi Cozinha Japonesa

A rodízio's real anti-waste discount, built as the whole site's thesis

A restaurant site built around one real, checkable discount: R$ 20 off per person if the whole table finishes what it orders. Every price tier shows both numbers together, never the discount alone.

Trísion Eyewear

One catalogue, a showcase for every reseller — brand site and multi-tenant platform for a Brazilian eyewear label

A brand's entire web presence used to be a Linklist page and a one-screen Canva site. Now there's a real catalogue, and every independent optical shop that resells the brand gets its own storefront — sharing the same products, never a copy of the brand's own site.

Prumo

MCMV pre-qualification and lead site for a Rio real-estate broker

A site that answers 'can I actually afford this?' before showing apartments — a six-question quiz gives a family an honest credit verdict in about a minute, before they ever compare units.

ART'hur

Motion-led portfolio and living archive for a visual director

A portfolio site that behaves like a sequence of film scenes instead of a scrollable page — one project fills the screen at a time, and a single scroll notch cuts to the next one like an edit, not a swipe.

Plexus

Extensible media processing engine with a non-destructive, WebGPU photo editor on top

A batch media pipeline system — like a personal Cloudinary — where the exact same 'recipe' you build by hand editing one photo runs unmodified across hundreds of files, with live progress and an editor that feels like Apple Photos.

Video Converter

Microservices video-to-audio pipeline with queues and Kubernetes

Upload a video, get the audio back as an MP3. The interesting part is that the work is split across independent services so heavy conversions never freeze the app.

Flora

An operations console for regenerative farming, built on a real satellite pipeline

A farm dashboard where a scheduled worker — never the app itself — asks satellites for ten different plant-health readings a field, so a farmer opens a map and sees exactly which corner of which field is struggling, backed by real Sentinel-2 imagery instead of a demo.

Headless Shopify storefront on Hydrogen
