...small-scale adjustments made across the codebase. The work is straightforward: tweak existing scripts, refine how a few pages render, and be sure the changes roll out cleanly without disrupting the live environment. Here’s how I’d like to handle the project: • I’ll share a concise task list and access to a staging copy right after we start. • You update the PHP files, touch any related HTML/CSS or JavaScript only where the change requires it, and keep everything compatible with PHP 8. • Once each item is complete, you push to staging so I can verify, then provide a brief changelog before we move to production. • Final delivery is the updated code plus that changelog, packaged so I can deploy with a single transfer. Clean, well-commen...
This is a data-dense B2B web application (search, admin, and reporting features) for professional users. The app's JavaScript (Stimulus) is fully built and working — this is a CSS/HTML/visual design engagement only. We are not looking for a JS developer. We're unhappy with the current visual design: weak typographic hierarchy, inconsistent spacing, and a look that doesn't feel like the polished professional platform we expect. We want a designer with strong visual and typographic judgement, not someone who just matches existing styles or uses AI. Scope: 12 views total need to be redesigned. Examples include search forms with multiple field types (dropdowns, multi-select, tag-style inputs), filter pills, and dense results tables (50+ rows, 6+ columns, mixed con...
...Key interaction: a simple progress bar shows where the user is in the sequence. Skip the extra animations and sound effects; clarity and calm are priorities. Once the final question is answered, a single concluding message appears, summarising the result or next steps. No introductory splash screen is necessary. Please supply the finished quiz as lightweight, mobile-responsive HTML/CSS/JavaScript (vanilla JS or a minimal framework is fine) so I can drop it straight into my existing site. All styling must be contained or clearly referenced, allowing quick colour tweaks should I need to adjust the pink tones later....
I need an experienced automation engineer (around 4-10 years working with Playwright in both JavaScript and TypeScript) to build and maintain a solid test suite for my web application. Scope • Target platform is strictly Web. • The suite must run reliably on Chrome and Firefox—cross-browser parity is essential. • Coverage spans all three layers: end-to-end flows, critical integration points, and a handful of fast unit tests around our helper utilities. Day-to-day you will wire Playwright into an existing Node/TypeScript repo, design a clean folder structure, and implement sensible fixtures, mocks, and test data factories. The code must be readable, reusable, and commit-ready with meaningful assertions and screenshots on failure. I will also rely on you...

I’m launching a small-business website and need a developer who can put together a clean, modern, and fully responsive one-pager using only HTML, CSS, and vanilla JavaScript. The layout will be simple—hero section, service overview, about/values, and a contact area—but it must look polished on mobile, tablet, and desktop. A lightweight navigation menu, a few interactive buttons, and concise animations will be enough to keep things engaging without loading the page with heavy frameworks. Deliverables I expect • Hand-coded HTML structure, organised and commented • Custom CSS (or SCSS) for styling, with media queries that guarantee smooth responsiveness • Vanilla JS to handle the navigation toggle, basic interactions, and any small on-scroll ef...
...services have evolved. I would like a polished, professional-looking landing page built from scratch and, at the same time, fresh content inserted into a couple of the older landing pages that still rank well. Main goal Update the website so visitors immediately see our current services and understand the value we provide. Scope of work • Design and code a responsive landing page (HTML5, CSS3, JavaScript; frameworks such as Bootstrap or Tailwind are welcome if they keep the markup lean). • Inject the new copy, visuals and calls-to-action into two previously built landing pages, preserving their existing URLs for SEO continuity. • Ensure all three pages carry a consistent, professional aesthetic—clean typography, balanced white space, and straightfor...

...handful of front-end glitches that are starting to frustrate users. Buttons drift out of place, forms sometimes refuse to submit, and certain pages break on smaller screens. The backend and database are solid; I only need precise fixes to the user interface. Everything sits in a Git repository. Once you have access, reproduce the reported issues, trace the root cause in the PHP templates, CSS, or JavaScript, and push clean, well-commented corrections. Please preserve the current structure—no heavy refactors—just targeted repairs that restore a consistent look and feel across Chrome, Firefox, Safari, and Edge. Deliverables: • Pull request containing all UI bug fixes with clear inline comments. • Brief changelog summarizing each problem, its cause, and the...

...smoothly, showing a small thumbnail preview and an upload-progress bar. • Post the files to a back-end endpoint that stores them in an organised folder (or bucket) and returns a JSON confirmation with filename, size, and a unique ID. • Keep the interface fast and responsive on mobile as well as desktop; MLBB players are mostly on phones. Tech is flexible—feel free to use React, Vue, plain JavaScript, or a lightweight framework you’re comfortable with on the front end, and Node, PHP, or Python on the server as long as it’s cleanly documented. After hand-off I need: source code, a quick setup guide, and a short README explaining where the files are stored and how the validation logic works. Once this is solid I’ll open a follow-up project for ...
...seamlessly between variants. The overall look must stay sleek—white space, refined typography, subtle motion, and a layout that adapts perfectly on mobile, tablet, and desktop. While the catalogue is the main attraction, I also need a concise About Us section to share the brand story and a Contact Us page with an embedded form and map. Deliverables • Fully responsive website (HTML 5 / CSS 3 / JavaScript or preferred framework) • Interactive product carousel integrated into the catalogue • About Us and Contact Us pages styled to match the main theme • Admin-friendly way to add, edit, and retire watch listings (CMS or custom panel) • Basic on-page SEO setup and Google Analytics readiness • Final hand-off with source files and brief ...

I already run Meta ads and have a working Squarespace site that pushes purchase data through Zapier into Facebook Conversions API, Brevo, and a Google Sheet. The basic flow works, but Meta still flags every event as “Missing user parameters” because four values never make it through: _fbc, _fbp, visitor IP address, and user agent. Here is what needs to happen next: 1. Add a lightweight JavaScript snippet to my Squarespace site (Code Injection is fine) that, on page-load, reads the existing Meta cookies (_fbc and _fbp) and also captures the visitor’s IP address and user-agent string. 2. Make those four items available to my Zap. I want them stored in a dedicated column for each field inside the same Google Sheet row that already holds the buyer’s email&md...

Visual identity I don’t yet have a logo, colour palette or brand fonts, so please factor simple brand-kit creation into the job. Once approved, this style should flow consistently through every page. Content focus The Services page must spotlight our core offer: Consultation and advice. Use clear calls-to-action so visitors can quickly grasp the benefit and move to the Contact form. Functional requirements ...
[Chennai-based freelancer is preferred as a visit to the customer's site may be necessary] My custom HTML dashboard is almost production-ready, but two areas still hold it back: WebSocket data transfer errors and overall front-end performance. The interface is built with vanilla HTML/CSS and JavaScript, streaming live data from a Cognex industrial machine vision camera over WebSocket. While the socket connects successfully, packets occasionally arrive corrupted or out of order, which breaks the real-time charts. I need you to trace the exact cause of these data transfer errors, patch or rewrite the send/receive logic as needed, and add graceful handling for edge cases such as dropped frames or partial payloads. At the same time, I’d like the dashboard codebase tighten...

...just three fields—name, email, and password—under the friendly heading “Create Your Account.” The look should be clean and minimalistic, blending effortlessly with a modern web layout, and the primary “Sign Up” button must be visually prominent to drive conversions. The form will live on an existing website (not a mobile app), so please deliver it in standards-compliant HTML, CSS, and vanilla JavaScript or a framework you’re comfortable with, provided it stays fast and lean.

...blocking touch events, then patch it so every form element and call-to-action responds smoothly on current iOS Safari and Android Chrome. A quick audit of any JavaScript libraries, event listeners, and CSS overlays that might hijack taps will probably be required, and I’m happy to supply repo access and staging credentials straight away. Acceptance criteria • All forms and buttons respond instantly on common mobile browsers—no dead taps. • No new console errors introduced. • Fixes pushed to Git with clear commit notes so I can follow the changes. If you’ve already wrestled with viewport quirks, z-index overlays, or JavaScript touch handling, you’ll likely solve this fast. Let me know how soon you can start and roughly how long...
...end-to-end—authentication, payments and real-time sync—on real devices and emulators. You’ll log defects in Jira with crystal-clear reproduction steps, confirm fixes on the next build and keep a tight feedback loop going until the issue count hits zero. Regression and integration coverage for our REST APIs will follow once the core mobile work is stable. If you’re comfortable layering in automated tests (JavaScript / TypeScript, React Native, Postman or similar) and wiring them into our GitHub Actions pipeline, you’ll have room to improve our velocity as well.

I need a responsive course application form built from scratch with clean HTML5, CSS3 and vanilla JavaScript—no WordPress, no Google Forms. The form should gather the usual applicant details (name, contact info, course choice, and any extra fields I may add later) and give clear, inline validation messages so mistakes are caught before submission. Keep the code modular: place the action URL or fetch/AJAX call in one well-commented section so I can plug in my own back-end or an email service like Formspree without digging through the markup. Light helper frameworks such as Bootstrap or Tailwind are fine if they stay lightweight; steer clear of anything heavy. Deliverables • A fully responsive .html file containing the form markup • Separate, well-commented .css ...
My business site needs a quick but thorough round of fixes. A few page sections drop out of alignment on certain screens, some internal links now point to 404s, and a couple of interactive bits no longer respond.

I’m launching a new online store and want it coded from the ground up in plain HTML, CSS and JavaScript rather than relying on Shopify, WooCommerce or Magento. The site should feel fast, lightweight and fully responsive while showcasing an AI-enhanced shopping experience. Core features I need integrated: • Real-time, AI-driven product recommendations that adapt to each visitor’s browsing and purchase patterns. • An on-page chatbot that can handle customer service queries, guide product discovery and collect leads for follow-up. Beyond those essentials, the usual e-commerce fundamentals—secure checkout, inventory display, order confirmation emails and basic analytics—must be baked in. Preferred tech for the AI layer is open: , a suitable third-pa...

I’m putting together a clean, responsive front-end for my own lifestyle blog and would like a developer who can translate mood-board ideas into real HTML, CSS and JavaScript. Content will range from everyday routines to travel snapshots, so visual storytelling is key. If you can weave in crisp typography, subtle animation and mobile-first layouts, we’ll be on the same page. The core deliverable is a set of templated pages—home, article, and archive—built with modern, semantic markup and a lightweight component framework (React, Vue or vanilla JS is fine as long as it’s modular). I’d like the codebase organised so I can hook it up to a CMS later. Beyond the basics, I’m open to features such as a photo gallery, newsletter sign-up or social-m...

I need someone to trace the root cause and deliver a clean, permanent fix so: • each image in that gallery (and any future ones I create the same way) launches its assigned custom URL in a new browser tab; • no existing styling or functionality on the rest of the site is broken; • you let me know what you changed so I can reproduce the solution later. You’ll be working directly in WordPress with the FooGallery plugin; familiarity with its link override options, WordPress hooks, and front-end debugging tools (Chrome DevTools, console, etc.) will be essential. If additional CSS, PHP, or JavaScript tweaks are required...
