    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 building a small C# utility that will crawl a target site, pull out every piece of on-page information I need (both the visible text and the images), and also save any PDF that the page links to.

You are free to approach this with HtmlAgilityPack, AngleSharp, HttpClient, Selenium, or any other .NET-friendly library you’re comfortable with, as long as the final code is clean, asynchronous where it makes sense, and easy to extend.

    I’m launching a dedicated platform that will stream T20 matches in real time.

    I’m running a rapid compatibility study for an upcoming viral TikTok campaign, and I need help from people who still use older or less-common Android smartphones—often called “live devices.” Your job is simple yet critical: push our landing page to its limits and tell me exactly where it breaks or misbehaves. What you’ll do • Open a private test link on your Android phone (any brand or carrier, the older the better). • Follow a short script that forces heavy scrolling, repeated form submissions, and fast video playback. • Note visual glitches, layout shifts, slow loads, or crashes. • Capture a quick screen recording (native recorder or a lightweight app) while you test. • Send me a brief report that includes your device mode...

    I’m building PulseTv, a live-streaming platform, and while I handle most of the core backend work, I need another set of hands to push the project over the finish line on both sides of the stack. Current stack & context • Database: MySQL • Realtime layer: native WebSocket connections for chat-bot hooks and audience messaging • Frontend preference: (React) • Streaming layer still pending: HLS and RTMP What I need from you 1. Frontend – Craft a responsive, clean UI in Next.js. – Set up solid state management (Redux, Zustand, or your preferred option) so chat, viewer counts, and live status stay perfectly in sync. – Wire everything to the existing REST and WebSocket endpoints. 2. Streaming features – Confi...

    I’m maintaining a news-focused application built with Angular and TypeScript, and a few irritating layout bugs are spoiling the user experience. Cards slip out of their grid, headers overlap at certain breakpoints, and some components ignore the flex settings meant to keep them tidy. My priority is to track these issues down, clean up the CSS/SCSS, and adjust any component code that’s contributing to the problem so every page renders predictably on desktop and mobile in Chrome, Firefox, Edge, and Safari. You’ll have Git access, a straightforward npm install/ ng serve workflow, and quick feedback from me as you submit fixes. Please deliver a tidy commit (or PR) with clear comments explaining what changed and why, so I can review, merge, and deploy with confidence.

    I need a single code-base (or as close to it as the platforms allow) that will let our audience stream our catalogue of movies and TV shows on Android TV, LG webOS, Roku and Hisense Vidaa sets. The project must be wrapped up within a month, fully tested on real hardware, and ready for each platform’s respective store submission. Core scope • Smooth HLS/DASH playback in HD and UHD where the device permits, with proper remote-friendly transport controls. • Home, genre, and details screens that pull metadata from our existing JSON API. • Continue-watching row and basic search. • Localisation placeholders so additional languages can be added later. Deliverables (one ZIP or repo per target) 1. Source code with clear build/compile instructions. 2. Signed p...

    Project Description: I am looking for an experienced Flutter developer to build a PPG (Photoplethysmography) mobile application.

The Goal: Turn the phone’s camera and flashlight into a sensor to measure: Heart Rate (BPM) HRV (Heart Rate Variability - SDNN) Stress Index based on RR-Intervals. Key Deliverables: Camera Sensor Module: Implement the Flutter camera package to stream raw image data.

    I need a small, self-contained website that mimics the official JEE (Main) score-card page but runs entirely offline on Windows. When I open the in any browser it should display an authentic-looking result with the subject-wise scores and corresponding percentiles I choose to hard-code or edit later. Key points • Platform: Windows only—no server setup; just double-click to open. • Format: Standard HTML web page styled with CSS (a little JavaScript is fine for neatness, not required for dynamic calls). • Data shown: Subject scores and their percentiles; no rank, category, or personal photo—those sections shouldn’t appear. Deliverables 1. , accompanying CSS, and any local assets (logo, fonts) packaged so they load from the same folder. 2. A sho...

    I need an engaging canvas built specifically as an educational tool for teens that revolves around the theme “Strength of a girl.” Think of it as a self-contained, interactive space—whether you approach it with HTML5 Canvas, an SVG-based board, or a graphics-rich PDF—where students can explore and reflect on empowerment, resilience, and real-world examples of female strength. Here’s what I have in mind: the finished piece should feel fresh and age-appropriate, with visuals and wording that speak to secondary-school learners. It must be easy for teachers to project in class or share online, and simple for students to navigate on their own. If you choose a web-based solution, keep load times light and make sure it works on standard classroom laptops, tablets, a...

    I have a detailed PowerPoint design that I want reproduced, line-for-line, in pure hand-coded HTML5 and CSS3. No WordPress, Wix, Webflow or any other builder—just clean, readable markup styled with Flexbox and CSS Grid wherever they make sense. Responsiveness & breakpoints • The layout must feel flawless on mobile (my primary focus) and scale smoothly up through tablet into desktop. • At 1920 × 1080 the pages should match the PPT grid and spacing exactly. • Please keep padding, font sizes and image placement within 1–2 px of the source slides. Interactivity Only a basic set of forms is required (contact and newsletter). If a sprinkle of vanilla JavaScript is needed for accessibility or validation, keep it minimal and unobtrusive.

    GPS Tracker Email Alerts
    2 dni left
    Zweryfikowany

    Inside one URL of my web-application I need a small, self-contained GPS tracking module. The moment a visitor lands on that page and grants location permission, the script should capture the latitude and longitude and immediately push those coordinates to my email inbox—no dashboards or databases, just a clean email notification every time. I do not mind what stack you choose as long as it plays nicely with standard browsers (the HTML5 Geolocation API, JavaScript, PHP, Node, or a lightweight webhook are all fine). The code must be lightweight enough to drop straight into an existing page without breaking anything and should degrade gracefully if the user blocks location sharing. Deliverables • Embeddable code snippet (client-side + minimal server-side for the mailer) &bull...
