I have a one page React site that is functionally complete but still looks a little unrefined on both mobile and desktop. I need a careful round of visual polish so the page feels consistently professional across breakpoints. Primary focus • Layout — tighten spacing and alignment so elements sit naturally in every viewport. No structural overhauls; just precise tweaks to existing flex/grid rules, margins, and paddings. • Typography — refine font choices, adjust sizes for readability, balance color contrasts, and establish a clear heading–subheading hierarchy. The codebase is a standard Vite/React setup with modular SCSS; you’re free to use plain CSS, Tailwind, or styled-components as long as the final bundle stays lean and easy to maintain. Delivera...

I want to launch a simple, online-only web app that lets people lay out and design their own graphic novels right inside the browser. The emphasis is on an uncluttered interface rather than a feature-packed publishing suite. It should be the PowerPoint of graphic novel creation. Users open the site, can create panel layouts, easily design panels, API integration to vistacreate clipart and API integration to nano banana should make creating comics fast and fun, then save everything straight to their own machine as a single local file—no sign-ups, databases, or cloud storage. Think Canva or PowerPoint for graphic novel creation and layout, simple enough for a child. The design should be uncluttered and intuitive. Because the app must run entirely online, it needs to respond smoothly...

I need a developer who can build a streamlined eCommerce site for selling physical goods. The entire experience should feel minimalist and clean—crisp typography, generous white space, and a layout that keeps customers focused on the products rather than on visual clutter. Core functionality starts with a rock-solid shopping cart: users must be able to add, edit, and remove items effortlessly, then move straight through a distraction-free checkout flow. I’m happy to integrate whichever modern platform, framework, or stack you feel suits this style best—whether that’s Shopify with a custom Liquid theme, WooCommerce on WordPress, or a lightweight headless setup using React + with Stripe. Key deliverables • Fully responsive storefront styled to the minimalist...

I’m looking for a web developer who can take me from concept to production on a web-based system that does two things exceptionally well: manage a reusable question bank and deliver an intuitive exam-taking flow for students. The core of the project is question bank management. I need to be able to upload hundreds and also single question of questions in one action (CSV, XLSX or similar), have them automatically slotted into the bank, and later pull any subset into a new test. Because I run IELTS and CELPIP preparation programs, the bank must comfortably store every format those exams demand—multiple-choice, short answer, essay style and any other default question types those modules require. Once the questions are in, I want to assemble exams dynamically: pick a template, s...

I have a personal poker game built as a React progressive web app. The core gameplay is solid, but one screen still looks like a rough wire-frame. I’ve attached a screenshot of that page; everything you see there keeps its current functionality, yet I want the visual design and flow re-imagined so it feels polished, intuitive, and mobile-friendly. Your task • Redesign that single page and supply updated React (JSX/TSX), stylesheets or styled-components, plus any supporting assets so I can drop them straight into my repo. • Make sure the new layout is responsive and visually consistent with modern card-game UIs. • Leave all existing logic intact; this is strictly a UI/UX lift. Please include a detailed project proposal, a Plesk access will be provided.

My team needs a seasoned full-stack developer to step in as a consultant who can transfer knowledge rather than write code. I’m specifically looking for someone confident across frontend, backend, and database layers who can translate that depth into clear, structured technical training sessions. Your core mission is to design and deliver training that sharpens our developers’ practical skills. Expect to break down real project scenarios, walk through architectural decisions, explain code quality best practices, and answer ad-hoc questions as they come up. We work mostly with JavaScript/TypeScript, React, Node.js, and PostgreSQL, so fluency in these (or closely related stacks) will help you connect quickly with the team. Deliverables • A short training plan outlining top...

Hi I will share the details with the shortlisted candidates. thanks

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...

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...

I’m kicking off a new directory platform and need a clean, well-structured starter template built with the latest stable version of Next .js. The goal right now is to receive a solid, extensible codebase that I can grow into a full-featured listing site over the coming months. Here’s what I expect in this first milestone: • A modern Next .js project scaffolded with TypeScript, app router, and server-side rendering already configured. • Reusable layout components (header, footer, dynamic sidebar) and a responsive grid ready to display listing cards. • Fully wired global state management of your choice (Context, Zustand, or Redux Toolkit—whichever you’re most comfortable maintaining). • Placeholder pages for Listing Detail, Category, and Acc...

I’m looking to get a small-scale CMS online fast. The front end must be built with React while the back end runs on Laravel. I’m comfortable if you lean on AI coding assistants to accelerate the build; the priority is clean, well-structured code that I can maintain later. Core expectations • A standard CRUD workflow for pages and posts, served through a straightforward React interface. • RESTful APIs (Laravel Sanctum or Passport is fine) with token-based auth so the front end stays decoupled. • Basic role and user management baked in from the start. • Solid, developer-readable documentation that explains local setup, environment variables, and deployment steps. Once everything is pushed, I’ll run the project locally and on a staging server;...

I have a working prototype built in Google AI Studio and I now need to take it from “demo” to a secure, production-ready release on both web and Android. First, I want every credential locked down. Both the API keys and the code itself must be protected: secrets moved to environment variables or Secret Manager, no keys exposed in the client bundle, and the repository cleaned of sensitive commits. A brief security checklist or automated scan that proves the hardening is complete will form part of the hand-off. Next comes a functionality sweep. I’m not sure whether anyone has formally reviewed the code, so plan to step through each user flow, patch breakages, and make sure the app genuinely meets Minimum Viable Product standards. User sign-in must switch to Google Authen...

I have a mature React codebase , and i need some to help me with some task one day

The goal is to craft a complete web application from the ground up, pairing a React.js front end with a Node.js back end and shipping a functional MVP within a month. I already know I want React for the client interface, so the build should follow best-practice component architecture, modern hooks, and a clean, responsive layout. On the server side, Node.js (Express preferred) will power a RESTful API, handle authentication, and connect to a persistent data store—MongoDB or PostgreSQL, whichever you feel best suits the use case. To keep expectations crystal clear, here are the concrete deliverables: • Git repo initialized with meaningful commits, README, and .env sample • React UI coded, styled, and wired to the API (state management via hooks or Redux) • Node.js...

I have an informational web application to be built and prefer to work with freelancers who are already based in Bengaluru so we can easily align on occasional in-person discussions and faster iterations. The project centres on a clean, responsive site that presents curated content rather than e-commerce or social networking features. Core requirements include: • Front-end: modern, component-based framework (React, Vue or similar) with SSR or strong SEO support. • Back-end: lightweight REST or GraphQL service, preferably in Node.js or Python, with clear separation of concerns and straightforward deployment to a standard cloud stack (AWS, GCP or Azure—whichever you are most comfortable with). • CMS or admin interface that lets non-technical staff update text, imag...

I have an existing web application built using React.js (frontend), Node.js (backend), and PostgreSQL (database), and I am looking for a highly experienced expert who can both thoroughly manually test and actively fix/repair the entire application end-to-end. This is not a testing-only role—the developer must identify and correct all issues in the codebase (frontend and backend). The scope includes detailed manual testing of all modules, user flows, validations, APIs, and edge cases; fixing all discovered bugs and errors; resolving console, runtime, and server-side issues; improving UI/UX where required; and making the complete UI fully responsive across mobile, tablet, and desktop devices using modern responsive design practices. The work must result in a stable, production-ready ap...

I need a clean, production-ready front-end for an ERP application built with React and Next.js. The back-end team will expose REST/GraphQL endpoints, so my main focus now is a modern, responsive interface that can consume those APIs and present data efficiently. What I expect from you: • A project scaffolded with the latest stable version of React, organised by feature modules so future sections of the ERP can be plugged in without refactoring. • Reusable components for common ERP screens (login, dashboard shell, data table with search/sort, modal forms, notifications). • State management wired up (Redux Toolkit, Zustand or another lightweight option you are comfortable with) and ready to connect to external endpoints. • Routing set up for at least a Home / Dashboard...

I am building a React Native or Flutter driver application—think Uber’s driver app, but with no payment or passenger-matching logic. The core requirement is a smooth integration with Waze for turn-by-turn navigation, wrapped inside a secure, professional-grade driver experience. The scope in a nutshell • Account & authentication: drivers create a profile that they can unlock via Face ID, password or fingerprint. During first-time setup the Face ID photo must be matched against the photo on the driver’s license (you may rely on any reliable on-device comparison API or a lightweight server call—open to your recommendation). • Daily workflow: once logged in, the driver starts a “shift”, completes a short pre-trip vehicle checklist, licens...

I have a live React.js application that needs a refresh on both looks and behavior. I will hand over all existing code, REST APIs, and design references; what I need is a developer who can quickly plug in and push the project forward. First, the interface needs attention. Several screens require a new layout structure and an updated color palette that aligns with our latest brand guidelines. I’ll supply Figma frames so you can translate them into clean, responsive JSX and CSS (or styled-components if you prefer). Alongside the visual lift, some functional pieces must evolve. A couple of small-to-medium features are still on the backlog, and a few of our current components need polishing to make them more robust. All calls to the backend are already exposed—your task is to wir...

I’m putting together a corporate head-count tracker and I want to move quickly from concept to a secure, production-ready application. The backend will run on Spring Boot; the frontend needs to be available both as classic HTML/CSS/JavaScript pages and as a richer React interface, so we can serve different devices and gradually migrate stakeholders toward React. Security is essential. I need full user authentication with clear role separation—Admin and User—implemented with Spring Security (JWT or another proven token strategy). Beyond wiring the login flow, I also want advice on best-practice password storage, CSRF protection, and anything else you see fit to lock things down. Where I need your help: • Designing the Spring Boot architecture, setting up entities, r...

I have an existing React app and need the key pieces of the Polymarket privy-safe-builder example wired straight in. The focus is on two things: • User authentication & management – replicate the Privy-powered flow so users can sign up with email or social, link a wallet, and stay logged-in across sessions inside my project. • Smart-contract interaction – expose the same Safe-based contract calls shown in the repo (read, write, signature gathering, error handling), but adapted to the contracts my dApp already references. The codebase you’ll be grafting onto is a standard Vite + React setup with already in place. I’ll add you to the Git repository once we start; you can work in a feature branch and open a pull request when complete. Acceptance crite...
