Cross-disciplinary design and development. Kromacat is a multiplatform personal photography ecosystem, web and Android on a single backend. A real home for the visual identity of photographers, illustrators, and creators. The public profile is personalized through visual themes, called Styles. The grid holds the curated portfolio. The feed follows whoever the user chooses, in chronological order. Pitch adds a chat-style space, one avatar and a one-way, chronological column of bubbles, for whatever doesn't fit the grid.
