    I run a product-led SaaS company and need a full-stack engineer who can work the same hours I do—9 am – 5 pm Pacific Time, Monday through Friday. Every feature we ship is built with JavaScript from back to front, so daily work revolves around a Node.js/Express API layer feeding a React web application. You will own end-to-end development: refining tickets in our Monday morning grooming call, writing clean, well-tested Node services, and pushing pixel-perfect React components that match Figma specs. I deploy through a GitHub-driven CI/CD pipeline to AWS (ECS + RDS). Familiarity with GraphQL, PostgreSQL, Docker, and Jest is helpful, but solid Node.js fundamentals and modern React experience are the non-negotiables. Success is straightforward.

    I am arranging a one-on-one, beginner-friendly coaching program that takes me from zero experience to confidently building small web apps with PHP and JavaScript. The focus in PHP will be basic syntax and functions first, then practical database interactions (MySQL with PDO or mysqli) and finally user authentication flows. On the JavaScript side I want to master core syntax, manipulate the DOM fluently, and understand asynchronous workflows with Promises. Sessions should be live (video-call or screen-share), highly interactive, and always anchored by short coding challenges so I can apply each concept immediately. Clear explanations, real-world examples, and patient troubleshooting are essential because I’m starting from scratch. To keep the learning structured, I w...

Also some elements overlap (mainly the menu), links don't work or text within certain sections isn't displayed or loaded anymore. I need an Elementor-savvy developer who can step in, trace the root cause(s), custom CSS or JavaScript, and deliver a clean, responsive solution.

    ...pixel-perfect, from-scratch recreation of built with clean HTML5 and modern CSS. Every scroll interaction, hover transition and subtle animation on the original page should feel identical in the final build. The layout must fluidly adapt to desktop, tablet and mobile breakpoints without losing fidelity or performance. You’re free to sprinkle in a light touch of vanilla JavaScript where CSS alone can’t achieve an effect, but no frameworks or heavyweight libraries—lean, well-commented code is the priority. Naming conventions should stay consistent so I can follow the stylesheet logic easily and tweak sections later. Deliverables • Fully functional source folder containing HTML, CSS (and any minimal JS) • All assets optimised and referenced locally...

    ...reads well from 320 px mobile up to large desktop, using percentage widths and media queries. • Semantic tags, labelled inputs, and ARIA attributes so screen-readers announce everything correctly. • Organized stylesheet (custom properties or SCSS compiled to CSS is fine) with comments showing the breakpoints you chose. • Built-in client-side validation hooks (HTML5 attributes are enough; no JavaScript required right now). • Tested in the current releases of Chrome, Firefox, Safari, Edge, plus iOS and Android browsers. Deliverables 1. containing the login form, logo placeholder, and minimal inline script if absolutely necessary. 2. (or compiled equivalent) that handles all typography, spacing, colours, and responsiveness. 3. A short read-me des...

    I want a modern, conversion-focused landing page that showcases pets for sale and feels just as polished on a phone as it does on a 4K monitor. The build needs to happen in Lovable (or a comparable tool that lets you export clean code), and I’ll need the full, unminified HTML, CSS, and any JavaScript you use so I can host it wherever I like. Visual style should be bright, welcoming, and clearly guide visitors toward the primary call-to-action—whether that’s clicking a “Buy Now,” “Enquire,” or “Adopt” button (we’ll finalise the exact wording together). Smooth scrolling, subtle animations, and concise copy blocks are all encouraged as long as the page still loads lightning fast. Key deliverables: • Fully responsive lan...

    I need a single-page HTML/JavaScript solution that visitors will open from an Android browser. The flow is: • On page load, the script checks—using any reliable browser-side technique—whether an APK with a package name I’ll provide is already installed on the device. • If the app exists, the page immediately launches it with intent:// (or a custom scheme, whichever is more robust across modern Android browsers). • If the app is not present, the page shows a clear “Download” button, lets the user fetch the APK, and then keeps polling at short intervals. • Once the user finishes the manual install and returns to the tab, the page detects the new installation automatically and redirects straight into the app without extra taps. ...

    ...models, an engaging background environment that fits the brand, and the interactive animations that tie everything together. I’m happy to supply reference photos, style guidelines, and dimension specs for each SKU; the actual modeling, texturing, lighting, and optimization for WebGL will be your responsibility. The finished work must: • Live natively inside a Shopify theme (Liquid, HTML/CSS, JavaScript) without breaking Shopify’s core functionality. • Load quickly on desktop and mobile—please plan for geometry optimization, texture compression, and lazy-loading strategies. • Offer smooth interaction: rotate, zoom, and swap product variants without lag. • Be documented well enough that my in-house team can update models or swap textur...
