I created a web experience inspired by PS1 game UI, cyberpunk visuals and old internet aesthetics 👾 “UNKNOWN ARCHIVE” is a retro-futuristic inventory filled with posters, CDs and corrupted digital artifacts. I used Google Stitch to generate and evolve the interface with prompts and visual references, exploring motion, hover effects and a UI that feels alive. 🔗 Project: https://stitch.withgoogle.com/preview/9399905294660220176?node-id=f2d2e066aa814c768ee39d333e9008cf @stitchbygoogle #GoogleStitch #Cyberpunk #GameUI #WebDesign

When century-old tradition meets Japanese precision 🇧🇷🇯🇵 Cachaça Nara was born from an extraordinary challenge: to create a brand that would honor deep Brazilian roots while incorporating the sophistication and rigor of Japanese processes. A farm from 1886. The only Nara oak plantation in Brazil. A spirit that needed to transcend categories and create its own narrative of excellence. We built from concept to packaging an identity that translates omotenashi, the Japanese hospitality that values every detail, every stage, every tasting moment. The result is a brand that doesn't compete on shelves, but creates its own territory of sophistication and authenticity. See the full case at www.yuza.com.br (http://www.yuza.com.br) 🥃

Creating a brand for a law firm is already challenging. With strict legal limitations, the challenge multiplies. ⚖️ For Davián & Sestini, we developed a monogram that unites the partners' initials while simultaneously referencing digital and fashion, the firm's areas of specialization. The result is a sophisticated identity that navigates the legal sector's restrictions without sacrificing personality and contemporaneity.

Any message from an unknown number is silently ignored and a 200 OK is returned to avoid retries.
