Modern Desktop App UI/UX

My desktop application is functionally solid, but the interface still feels like a placeholder. I want every screen— from login to settings— re-imagined in a modern, sleek style that feels instantly intuitive. Clean typography, balanced white space, subtle motion and a consistent design system are the priorities, and I’m open to the specific tool you prefer (Figma, Sketch or Adobe XD all work for me) as long as the final assets are easy for my developers to implement.

Here’s the flow I have in mind:
• Discovery session where I walk you through the current build and the user personas.
• Wireframes that nail down information hierarchy.
• High-fidelity mock-ups with interaction notes so the dev team can reproduce every hover state and transition.
• A small component library (buttons, inputs, iconography, color variables) delivered in a shareable design file.

Please include links or attachments to past work that show similar desktop app projects so I can quickly gauge fit. No need for a long proposal— strong visuals speak for themselves. I’ll be available for fast feedback and aim to move into production as soon as the design system is approved.
