    I’m preparing the next release of and the current frontend is showing its age. The underlying business logic is solid, but the user-facing components have become tangled after multiple quick iterations. I need an experienced frontend developer to step in and refactor the existing UI components so they are clean, reusable, and easy to maintain. What you’ll actually be touching is the component layer only—no backend or database work is required. Styles and core JavaScript behaviour are mostly fine for now; the priority is reorganising, simplifying, and, where sensible, rewriting the visual components to follow modern best practices. That includes breaking monolithic files into smaller units, removing dead code, improving naming conventions, and making sure each component ...

    My site looks perfect on desktop and tablet, yet several elements slide out of place on mobile screens. The issue is strictly a visual one: mis-aligned sections, buttons that drift, and text that refuses to center. No JavaScript bugs—just CSS/HTML that needs tightening for small viewports. I’ll give you repo or FTP access along with screenshots of the current problem and the desired positioning. All changes should be limited to the frontend codebase (mostly a handful of Sass files and a responsive utility class). Once finished, the pages must render correctly on common mobile breakpoints (320-414 px) without introducing regressions to larger devices. Deliverables: • Updated stylesheets (or scoped overrides) that resolve the alignment issues • Brief changelog so I ca...
