Started as a designer. Learned to code because I wanted my designs to ship the way I meant them to. Today I do both, for founders and small teams who care how their product feels, not just what it does.

Half designer, half developer, fully accountable for both. That's how I ship websites where every detail survives the trip from concept to production.

Core Tools

Webflow

My daily driver. Where most client projects live. Flexible enough to design freely, structured enough for the client to update it without me. The right trade-off for most of the work.

Astro

For projects that need to be built from scratch. Editorial sites, portfolios, and layouts where the design has to breathe fully. Astro is where I write the site line by line and keep every decision under my control.

GSAP

Motion isn't decoration. It's how a site tells you it's alive. Scroll, hover, transitions. This is where a page stops loading and starts breathing.

Figma

Where the thinking happens. Design systems, tokens, wireframes, iterations. Every project starts here before a single line of code.

Our work

Project
Gabriel Granjeiro Designer & Webflow Developer

The personal website of Gabriel Granjeiro, CEO of Gran, an edtech with 500K+ students and Nasdaq-level recognition. The challenge: translating a high-impact trajectory into a digital experience that builds authority and connection. From design to code, I built the entire page in Webflow with a focus on performance, storytelling and conversion.

Project
ARBA Designer & Web Developer

ARBA needed to turn regulatory compliance into market authority. I designed and developed the full website, from Figma to WordPress, with scroll-driven animations and micro-interactions that elevate the brand above the industry standard.

Project
Mobilitex Webflow Developer

Mobilitex is a leading Brazilian company in smart infrastructure for tunnels and highways. They needed to translate their technical complexity into a matching digital experience. I redesigned the interface in Webflow and built custom GSAP interactions, including a case gallery with drag, inertia, and cinematic transitions.
