Frontend Developer Needed for Marketplace Website (HTML, CSS, JavaScript)

I have built a marketplace website using HTML, CSS, and JavaScript.
The basic structure is ready.
Now I need an experienced frontend developer to:
• Improve UI/UX design
• Make layout clean and professional
• Improve spacing and alignment
• Fix responsive issues (mobile friendly)
• Optimize page speed
• Improve header, hero section, categories, recent ads, and footer
• Clean JavaScript functionality
Backend is NOT required at this stage.
Only frontend polishing and professional finishing needed.
