Desktop App UI Designer Needed

I’m refreshing a mature desktop application and want a clean, modern user interface that feels intuitive the moment it launches. The task is pure graphic design—specifically user interface design—so I’m counting on your expertise in layout, typography, iconography, and visual hierarchy to bring the screens to life.

Here’s what I need from you:
• High-fidelity mock-ups of every primary screen, delivered in an editable format (Figma or Adobe XD are fine).
• A compact style guide that documents colours, fonts, spacing rules, and reusable components so my developers can implement the design without guesswork.
• A small icon set for in-app actions (around 15-20 icons) that matches the overall visual language.

Smooth hand-off is essential. Please package assets clearly and label layers so my development team can dive straight in. If you’ve redesigned complex desktop applications before—especially ones with dense data views or multi-panel layouts—include a link or two when you reply so I can gauge fit quickly.

I’m ready to start as soon as we agree on scope and timeline, and I’ll be responsive with feedback to keep momentum high.
