    I’m building a browser-based stock management platform and I’d like it developed with the classic MERN-style pairing of React (frontend) and Express with PostgreSQL (backend and database). The system will be accessed externally by both Suppliers and Customers, so clean, responsive UI components and a secure REST API are essential. Core scope The application must let us track inventory in real time, move orders through their full life-cycle, and surface clear reporting and analytics dashboards. Three permission tiers will exist—Admin, Manager, and Viewer—each seeing only the screens and actions appropriate to their role.

    My 15-18 page site is functionally complete; it simply needs a sharper, more professional look. The main priority is typography—establishing a clear hierarchy, choosing a refined font pairing, and ensuring consistent spacing and rhythm across breakpoints. The existing color palette and layout work well enough, so keep structural changes minimal and focus on elevating visual polish rather than adding or removing features. I’ll give you Git access to the current codebase plus a staging URL. Work directly in the components, global styles, or utility classes as you see fit (CSS Modules, styled-JSX, Tailwind, or plain Sass—whatever fits smoothly into the project). No wireframes or references are provided; I trust your design judgment. Deliverables • Updated styles comm...

    I have a 14-day window to produce five custom web pages that feel modern and minimalistic while presenting information more clearly to our users. The first of these is the Home page; the remaining four pages will follow the same visual language once the core design pattern is approved. What I need from you • Craft clean, semantic HTML5 and CSS (you may use SCSS or Tailwind if you prefer) for all five pages, keeping everything truly mobile-first. • Hook the finished front-end to our existing backend API that supplies inventor-related data; fetch, display, and refresh that data smoothly without full page reloads. • Optimise for performance and accessibility as you code, making sure layout shifts are minimal and the pages pass common Lighthouse checks. • Hand over...

    I’m building a lean, first-release platform that matches companies that have spare warehouse space with businesses that need it. The scope is intentionally tight so we can validate the idea quickly while still delivering a usable service. Core user flow • Suppliers register and publish an offer that clearly displays storage size/type, price per unit, and availability dates. • Customers browse the catalogue and can instantly narrow results by location, price, or size. • Both parties receive email confirmations at each step (offer posted, request sent, booking status changed).

    I’m looking to tighten up the Collection Builder in our headless SveltyCMS (next branch). The work is focused on three improvements: 1. Finish the nested drag-and-drop treeview layer so users can both sort items inside a collection and reorder entire categories with a smooth, flicker-free UX. (dnd-action) 2. Streamline the way new categories and collections are spun up. A guided widget should let users pick the content-management template, name it, save, and see it appear instantly. 3. Add a safeguard that watches for schema or GUI changes that could break existing data; when a risky change is detected, the user must get a clear warning and confirm before the change is applied. Everything lives in this repo: I’ll review the work through a clean pull request that...

I don’t have a formal style guide, so I’ll rely on your recommendations. Ideally you’ll audit what’s there, propose small UI tweaks in Figma or directly in code, then ship concise commits or a pull request that I can test in staging.
