My current responsive website designed in reactjs and mongodb as backend and hosted on Azure. I want to keep the existing content and site structure but update the appearance so that every page looks modern, clean, and consistent across desktop, tablet, and mobile. I already have several reference sites whose aesthetic I admire; I’ll share those links once we start so you can see the level of polish I’m aiming for—think generous white space, crisp typography, subtle accents, and intuitive navigation cues. Here’s what I need from you: • Provide me a crisp modern layout based on my existing template and update the contents of all the pages • A concise style guide covering colors, fonts, iconography, and spacing rules • Export-ready assets and any source files (Figma, XD, or Sketch—your choice) Responsive best practices are non-negotiable, and smooth handoff to my developer is essential. If you have front-end build skills, let me know—though design excellence is the priority. Please include a link to your portfolio with comparable “before-and-after” redesigns so I can see how you transform dated layouts into fresh, engaging interfaces. I am also looking someone who has experience in ReactJs and MongoDb and do some development changes as follows: 1. Create admin panel to drive all the front end pages 2. Create a inventory functionality to maintain stocks and send notification as the inventory reaches low 3. Implement Subscribe to Newsletter functionality 4. Implement Donations functionality 5. Implement Gallery functionality 6. Implement Events functionality 7. Implement Marketplace functionality 8. Implement My Account functionality
