    ...receive: • Final text for each section • A simple mood board that covers colour palette, typography, and spacing guidelines • Rough wireframes that show hierarchy and desired interactions Your task is to build the live site, apply the style guide with pixel-perfect consistency, and make sure every page loads fast and passes basic accessibility checks. Clean, semantic HTML5/CSS3, lightweight JavaScript, and responsive best practices are expected; if you prefer WordPress or Webflow for streamlined upkeep, I’m open to that as long as the end result remains lean and minimalist. Key acceptance criteria: 1. The published site matches my design ideas with no unnecessary visual clutter. 2. Layout remains intact on common breakpoints (≥320 px). 3. All l...

    ...catalogue I’ve uncovered several broken features that are costing sales. On many product pages the main and thumbnail images refuse to load, variant titles or prices sometimes display the wrong information, and once customers add an item, the shopping cart itself intermittently drops products or ignores quantity changes. I need an experienced Shopify developer who can dive into the theme’s Liquid, JavaScript and app integrations, pinpoint the root cause, and patch it without disrupting live traffic. You’re welcome to work in a duplicated theme first, but I do need rapid turnaround and clear communication while you work. Current Issues: • Some product images are broken or not displaying correctly. • Product price text is missing or not visible on cert...

Players should be able to create an account with a traditional email-and-password flow or jump in through a social login provider; once inside, their best times and completed-puzzle counts need to be stored so a running leaderboard can appear on the home screen. Because I’m going for a clean, distraction-free look, every page—including the puzzle canvas, the auth screens, and the scores page—should follow a minimalistic design language: neutral palette, plenty of whitespace, crisp typography. To keep expectations clear, here is what I need back from you: • A Flask project ready to run with virtual-env requirements.txt. • Jinja2 templates and static assets (C...

    I need a production-ready landing page for a fashion e-commerce brand. Everything must be coded from scratch in vanilla HTML, CSS and JavaScript—no frameworks, no external libraries—so the files stay lightweight and easy to maintain. Design aesthetic Think high-end editorial: Cormorant Garamond for headlines paired with Barlow Condensed for supporting text, generous white space, and an elegant custom cursor that subtly reinforces the brand. I already have a few color ideas in mind but no fixed palette, so I’m happy to collaborate on the final scheme as long as it complements the typography and feels premium. Hero section I want the first fold to feel alive. A dynamic, parallax-style animation or a short looping video background that responds smoothly on scrol...

    ...tone; everything else (fonts, palette balance, layout) needs to align with that aesthetic. Core sections • About Us – concise story, mission, team photo. • Gallery – an easy-to-update image grid or slider to showcase finished spaces. • Contact Us – location map, email link or basic mailto form, and phone details. Please deliver clean, well-commented HTML5, CSS3, and a touch of vanilla JavaScript if needed for the gallery. No CMS or backend is required—just static files I can host anywhere. Ensure the pages load fast, display well on mobile and desktop, and are structured for basic on-page SEO (semantic headings, alt text on images). I will supply the logo and project photos once we start; you handle layout, colour harmony, and any s...

    ...calls and treat them exactly like real technical interviews. During each 45- to 90-minute session you will share your screen, think out loud, and solve data-structure, algorithm, and the occasional system-design problem in real time. To make sure the sessions feel authentic you should already be comfortable white-boarding (or using an online pad) in at least one major language—Java, Python, JavaScript, C++, or a similar modern stack is fine—and be able to defend your approach under follow-up questions. Clear, confident English is important so the interviewers can probe your reasoning without friction. When you reply, tell me: • the language(s) you want to use, • a brief note on your professional background and past interview experience, • your...

    My current site is built with plain HTML, CSS and a bit of vanilla JavaScript. It works, but the look now feels dated. The only objective of this project is to refresh the visual design and add Contact Us feature. Where I need your creativity most is in the colour scheme and overall page layout. I have a general sense of style—light, spacious, friendly—but no fixed palette or wireframes, so you will help set the visual direction. Responsive behaviour must remain intact (mobile, tablet and desktop), and any CSS or JS you add should keep page weight lean and standards-compliant. Deliverables • Revised HTML templates (header, footer, three types of content pages i.e. Landing, Services andtestimonials) • Modular, commented CSS/Sass with the new colour palette...

    ...must show up in Odoo in real time. Beyond the order itself I also need the integration to pull across the related customer record and keep product inventory levels accurate in both systems.
