UI/UX Designer to complete a travel web app mockup (Adobe XD)

Description:
Important note: The indicative budget (€20-40) is fixed and non-negotiable. If you disagree, please do not submit a bid.

We already have a design base created in Adobe XD for a travel web app (searching for flights, hotels, attractions, and itineraries). Some screens are complete, others are partial and need to be refined or integrated, and others have never been finalized (so we need advice on how to proceed).

We are looking for a UI/UX Designer who can:

Refine existing pages, maintaining the defined style.
Complete missing sections (desktop, tablet, mobile).
Organize reusable components and templates.
Provide clean final files, ready for front-end development.

Requirements:
Excellent knowledge of Adobe XD (or Figma).
Experience in travel, booking, and e-commerce projects.
Focus on visual consistency, user experience, and responsive design.

Deliverables:
Updated and complete XD files.
Mobile/tablet versions of main pages.
Mini design system (palettes, fonts, buttons, inputs, tabs, etc.).

Budget and timeline:
Fixed budget €20-40. Short deadlines (to be agreed upon, maximum 1 week).
