    I need a front-end developer who can translate my vision into a fast, fully responsive website built with React, modern JavaScript, clean HTML5, and modular CSS.

The site will include several content-rich pages, subtle yet engaging animations, and a component structure that is easy to maintain. Accessibility and cross-browser consistency should be treated as first-class requirements, and the final code must be production-ready, well-commented, and neatly organised in a Git repository. Please send a detailed project proposal outlining your approach, estimated timeline, key milestones, and any past work that demo...

    I’m rebuilding my Shopify store and need someone who can handle both the look-and-feel and a very specific piece of functionality: a customer-delivery-agent feature that plugs seamlessly into Shopify. In short, visitors must be able to assign or track their own delivery agent from the storefront, and the back-end has to reflect that choice all the way through to order fulfillment. Your role starts with refining or replacing the current theme so the experience feels polished and fast. From there, the custom integration becomes the priority. Whether you tackle it by extending an existing app or by coding a lightweight private app from scratch is up to you—as long as it works reliably, respects Shopify’s API limits, and keeps the admin dashboard clean. I’m open on ti...

    I am building a React-based analytics dashboard that blends traditional e-commerce features with rich, interactive visualisation. The frontend should expose three core user flows—product catalog browsing, a lightweight shopping cart, and secure user accounts—while simultaneously presenting business metrics through charts, tables, and geographic maps. React 18 will be the framework of choice. Feel free to introduce TypeScript, Redux Toolkit (or Zustand) for state, and a component library such as MUI or Ant Design so long as the final bundle stays lean. For the visual layer, any proven library—Recharts, , Victory, or D3—works, provided the components are responsive and can be themed to match the existing style guide. Key expectations • Clean, component-driven...

    I want to give my customer-facing multi-commerce app a fresh, premium look without touching any of the underlying business logic. The current build is React.js; I simply need the entire user interface re-imagined, delivered both as a polished design file and as ready-to-drop-in React components. Scope & vision • Mobile-first layouts that gracefully expand into desktop-first views • A white-dominant palette with subtle blue accents for a clean, modern feel • Industry-standard flows for Product Listing, Product Detail, Cart and Checkout . Liquid Glass UI feel and animation Product Listing Page I’m flexible on the exact layout—grid, list or even masonry can work—so long as the final choice suits the overall concept and performs well on all bre...

    I need a small, self-contained weather widget that anyone can open through a single URL. When the page loads it should immediately show the current conditions plus a multi-day forecast, all rendered graphically—icons, temperature charts, or any other visual approach that gives the information at a glance. The widget must let visitors change the location on the fly (city name, ZIP code, or GPS lookup). As soon as the user switches places, the visuals should refresh with the new data. I’m fine with any reliable public weather API such as OpenWeatherMap or WeatherAPI; feel free to recommend the one that best supports a clean, rate-limited solution. Responsiveness is important—phone, tablet, and desktop should look equally polished. I’d like modern, lightweight co...

    I already have a working landing page for my app () built in React, but the visual layer needs a final polish. The underlying code and copy can stay as-is; what I need is a design-driven refresh of the layout, colour palette, and the images/icons that support the brand story. You will work directly in the existing React repository, streamlining the component structure only where it helps the new look. I’ll supply my current brand guidelines—logo files, primary/secondary HEX values, spacing rules, and a small icon collection—to anchor the redesign. Feel free to propose subtle variations as long as the core guidelines remain intact. Deliverables • Updated React components (JSX, CSS/Styled-Components) reflecting the revised colour scheme • Optimised and p...

    I’m looking for an experienced developer or small team to build a reliable real-time data scraping system for Evolution Gaming live game shows, using an authenticated LeoVegas session, and integrate it into my existing website SpinLytics.com. This project is strictly focused on data reliability. Evolution Gaming does not provide public APIs, so the system must extract live round results directly from the authenticated client session. A working and stable data scraper is mandatory and must be guaranteed by the developer. The system must collect live round data for Evolution game shows such as Crazy Time, Monopoly Live, Dream Catcher, Funky Time and similar. Each round result must be captured immediately when officially published, without missing rounds, without duplicates and in cor...
