Mercado Play, reimagined in dark mode. 🎬🌙
This concept started with a feature I missed in the app: a dark theme built around the streaming experience.
I chose darker surfaces to give movie artwork more presence, reduce visual distractions, and create a more cinematic atmosphere. The signature yellow remains an accent, highlighting key actions and keeping the brand recognizable.
Beyond the palette, I refined components with a purpose:
✦ Larger featured artwork for stronger visual impact.
✦ Clearer navigation and selected states to guide browsing.
✦ Watchlist filters and visible playback progress to support returning viewers.
✦ A prominent “Watch for free” button to communicate the offer immediately.
The goal: make the experience feel more polished and immersive, strengthening its perceived value while keeping the content at the center.
An independent redesign concept exploring visual direction and interaction ideas.

Design that breaks brands out of the cocoon.
Language can be a portal, where each word opens a passage to new worlds. Yet in the language school market, many brands still communicate in similar ways.
With MEKHO, the goal was to move away from traditional academic imagery without losing credibility or structure. The challenge was to translate depth and authenticity into a consistent visual system for digital environments.
The logotype features angular strokes to convey precision. The symbol combines stylized bat wings, representing guidance, with a form that suggests a coded sign, reinforcing language as a system to be deciphered. The palette builds authority through dark tones, while green acts as a calculated contrast, signaling sophistication and direction.
The result is an identity that positions MEKHO as an immersive brand focused on real communication.

Alquimia do Sabor is a vegan confectionery brand that transforms plant-based ingredients into sensory experiences filled with care, consciousness, and meaning. More than sweets, the brand creates everyday potions, creations that awaken memory, affection, and presence.

This is the essence of the brand: a hybrid space that connects literature and botany as two forms of care. Here, books are not merely objects, they are seeds of possible worlds. And flowers are not just ornaments, they are gestures of affection, small breaths that soften the day.

NÓRIA is an artisanal fashion studio that brings together gesture, technique, and silence. Each piece emerges as a study of form: soft curves, natural textures, and a drape that follows the body’s own flow. The process is slow and intentional — stitching that respects time, fabric, and touch.
The visual identity begins with the central symbol: four continuous loops inspired by the running stitch. It represents the movement of the thread, the repetition of the gesture, and the delicate precision of patternmaking. The neutral, mineral palette reflects the studio’s aesthetic: calm, tactile, organic. Fine, gentle typefaces support the brand’s editorial character. Graphic elements derived from the loop create visual rhythm, as if the motion of sewing extended across the entire system.

They came back for a second project, that's the only review that matters.
Premium wasn't enough for ListLift. The full Webflow redesign leans on image-led layouts and B2B clarity to make the brand feel as high-end as its offer.

I’m currently rebuilding my portfolio, step by step. It’s been both interesting and challenging to curate and develop case studies from over 11 years of work.
I’d love to hear your thoughts so far

Submission for #levelupwithbubble
App Name: STUDYO
Category: Education & Learning
Live Link: https://gabrielcastrodias.bubbleapps.io/version-test
The STUDYO prototype starts with a simple idea:
what if learning worked more like thinking?
Instead of linear formats, STUDYO organizes knowledge through connections. From a single topic, AI generates a structured mind map, revealing key concepts and their relationships.
Each node opens layered content — from summaries to deeper explanations, supported by images, videos, and curated references.
STUDYO also introduces a collaborative layer.
Existing maps can be reused, expanded, and reorganized, allowing knowledge to grow over time through contributions.
Flexibility is central.
Users can reshape structures, move ideas, and define their own way of learning.

I developed the branding for DICEO — a German company built around the concept of transforming data into meaningful, actionable information.
DICEO stands for Data and Information Cycle for Elevator Optimization, and the entire brand was designed to reflect this core idea: collecting, organizing, and cross-referencing data from elevators to generate smarter, more efficient solutions.
The visual identity is rooted in this logic. The logo is constructed from two integrated data blocks, creating an intersection that forms the letter “D” — a direct representation of data connection and information flow. This geometric approach reinforces the idea of structure, precision, and intelligence behind the system.
