Web Application Update & Fixes

I’m planning a thorough refresh of my existing web application and need help on three fronts:

1. User Interface
The current screens feel dated. I’d like cleaner visuals, modern components, and a smoother overall experience. While I haven’t finalised the exact look-and-feel, I do want the layout, colours, and navigation to feel cohesive and intuitive across desktop and mobile.

2. Content
Some copy is outdated and a few pages need reorganising. Part of the task will be to replace old text, adjust headings, and ensure everything flows logically after the UI changes.

3. Backend Bug Fixes
Intermittent errors crop up during user sign-up and data retrieval. I need these squashed, along with a quick audit to be sure no hidden exceptions are lurking. Database structure is solid, so this is mostly about debugging existing code and tightening error handling.

Codebase access (repo plus staging server) will be provided. Once the visual updates are in place and the bugs ironed out, I’ll review on staging; after approval, you’ll push to production.

Deliverables
• Updated front-end templates/stylesheets
• Revised page content uploaded and verified
• Patch commits that resolve current backend errors
• Brief change log explaining each fix or enhancement

Please estimate how long you’ll need once you’ve seen the code, and highlight any similar projects you’ve tackled.
