How

Tech stack and technical decisions:

• Frontend: React, TypeScript
• Backend & Runtime: Tauri v2 (Rust)
• Database: SQLite
• Key Rust Crate Ecosystem: sqlx, tokio, walkdir, image, kmeans, palette
• AI Assistance: Used for building color search algorithms and troubleshooting Rust/SQL during development

Why Rust + Tauri instead of Electron?
Building a high-performance Digital Asset Manager requires fast file indexing, background thumbnail generation, and a responsive UI all running simultaneously. Electron’s higher RAM footprint and single-threaded nature wouldn't provide the level of performance this tool demands, so I chose Rust despite being on my learning journey with it!

What's next?

• Give multimedia support for the moodboard, like PDFs, videos, 3d objects and so on...
• A mobile version for tablets/smartphones??? I like the idea but I have no enough skill yet...
