UX/UI Design Audit – Car Auction Site vs. Market Standards

I'm launching a car auction/sales platform targeting international buyers, particularly in the Gulf region. I have completed a full Figma design, and I've built a working website mockup ready for review. I need an experienced UX/UI expert to audit the design against industry best practices and competitor sites. What I'm Providing: I'll give you a fully navigable website mockup with a test login so you can experience the actual user flows firsthand. You'll be able to click through the entire platform—from browsing listings to vehicle details to the bidding/inquiry process—just like a real user would. This isn't static Figma screenshots; it's an interactive prototype you can actually use. What I Need: Live Competitive Analysis – Navigate our mockup, then compare it against top car auction/sales platforms: Collecting cars, Bring a Trailer, Cars & Bids, Safqa Auction. Evaluate user flows, button placement, information hierarchy Identify where our design diverges from market standards (and assess whether that's intentional or problematic) Interactive UX Audit – Test our flows firsthand: Evaluate user flows, button placement, information hierarchy Listing browsing → vehicle detail → bidding/inquiry flow Checkout/transaction flow (if applicable) User navigation patterns and intuitiveness Mobile responsiveness Identify friction points and dead ends Comprehensive Feedback Report – Deliver a detailed report including: Screenshots from our site and competitor sites side-by-side Specific UX issues with problem areas highlighted Best practices recommendations for each flow Prioritized list of improvements for optimal user experience Corrected mockups or detailed design specs for critical fixes Clear actionable steps to implement changes Ideal Candidate: 5+ years UX/UI design experience (e-commerce/SaaS preferred) Familiarity with design systems and component libraries Experience auditing against competitive landscapes Ability to provide mockup corrections and detailed design specs, not just written feedback Comfortable working in Figma Strong documentation and communication skills Deliverable: Professional audit report with competitive screenshots, flow analysis, prioritized recommendations, and corrected mockups (Figma file or high-res mockups).
