    I’m looking for a developer who can take my initial idea—currently summed up as “Hello mister”—and turn it into a fully functional website. At this stage, the main requirement is getting a clean, responsive site online; I’m open to whether it ultimately becomes an e-commerce storefront, a blog, or a portfolio, and I’d value your guidance on the best direction. Here’s what I need: • A modern, mobile-friendly layout built with reliable web standards (HTML5, CSS3, JavaScript or a preferred framework). • Basic pages such as Home, About, and Contact, with room to expand later. • Easy content management—WordPress, Webflow, or another intuitive CMS. • Initial SEO setup so the site is index-ready. • Integration...

    Responsive Figma Mobile Screens

    Ověřený

    I have a straightforward job: design 5–6 clean, responsive screens in Figma that will look great on both mobile phones and tablets. Each screen is mostly text-based—think H1/H2 headings, short paragraphs, a form field or two, and clear call-to-action buttons. No complex dashboards or animations, just polished layout, good hierarchy, and consistent spacing. Here’s what I need from you: • A single Figma file with all screens organised in frames for mobile and their tablet counterparts. • Styles and components set up so I can tweak colours or text later without breaking the layout. • Export instructions or assets only if any custom icons or illustrations are added. No agencies please. Budget is 1200 rupees.

    I need two clear steps completed inside my Square Canada account. First, generate a “copy payment link” that I can share with customers and test it to be sure funds settle correctly. Right after that, use the Square Online tools to build a minimalist storefront page whose sole focus is to display my products. A clean white-space layout, simple typography, and prominent product cards are essential; no extra banners or clutter. The page should load quickly on mobile and desktop, inherit my brand colours once I supply them, and keep the usual Square checkout flow untouched. Please work directly in my Square dashboard (I will grant temporary access) and deliver: • A working payment link ready to paste anywhere, with confirmation screenshots. • A live Square Online p...

You’ll be collaborating with me through GitHub pull-requests and brief video or chat sessions whenever a tricky issue comes up. Clear, well-commented code, unit tests where sensible, and thoughtful commit messages are what I expect in every contribution.

    I have the layout sketched and the content ready; what I need now is a motivated junior developer who can turn those wireframes into a lively, responsive website. The build will rely on solid HTML & CSS structure and clean JavaScript, but the real focus is on bringing the pages to life with smooth, eye-catching animations—think subtle micro-interactions as well as larger, scene-based transitions. Here’s how we’ll work together: I’ll supply the page designs, brand assets, and a clear animation brief. You’ll translate that into semantic markup, modern CSS (Flexbox/Grid), and JavaScript-driven effects. If you already play with GSAP, ScrollTrigger, or similar libraries, that’s a plus, yet vanilla JavaScript solutions are perfectly welcome as long as per...

    My former e-commerce site only survives on the Wayback Machine. I need it revived as a clean, lightweight set of static HTML pages that I can upload anywhere. What matters most is that every word of copy and every image you see in the archive makes it across intact. The exact old layout is less critical; I’m happy with a fresh, responsive structure as long as the pages feel familiar and all content is present. After the pages are rebuilt, wire in a basic PayPal shopping cart—standard “Add to Cart” and “Checkout” buttons for each product are all I need.
