My self-hosted Paperless NGX instance still performs its core duties, yet the interface looks dated and makes everyday use less pleasant than it should be. I want to breathe new life into the project by giving the user interface a thorough makeover—cleaner layout, modern styling, and smoother interactions—while keeping all existing functionality intact. You’ll work directly on the current codebase, update the templates, stylesheets, and front-end assets, and hand back a version that feels fresh without disrupting my stored documents or workflows. Please include any design assets or component libraries you introduce, plus clear instructions (or a simple script) for building and deploying the updated UI so I can roll it out on my server with confidence. If this sounds like something you can handle, show me a sample of similar interface revamps you’ve done and tell me roughly how long you expect the upgrade and hand-off to take.
