    Rapid Shopify Store Build

    I plan to launch a sleek, mobile-first Shopify store and need a developer who can take it from blank theme to live site within 7 days. The focus is on speed, clean UI, and rock-solid SEO so the shop is discoverable from day one. Core requirements • Build the shop in Shopify’s latest Online Store 2.0 framework, styling it with modern Liquid, HTML5, CSS3, and lightweight JavaScript. • Ensure every page is fully responsive and scores well on Google PageSpeed for both mobile and desktop. • Configure a secure, fully tested payment gateway (Stripe and/or PayPal; open to other recommendations) so customers can check out without friction. • Optimize on-page SEO—meaning logical heading structure, meta tags, alt text, and clean URLs—so products r...

    ...final-year project I need a fully functional mobile application that runs smoothly on both iOS and Android. The main purpose of the app is to help users keep track of their overall health in relation to the medicines they take.

    Fix Shopify Variant Button Logic
    S&#039;est terminé left

    ...both buttons together. The goal is to let Liquid decide which single button to show: • If the selected variant is in stock, display only “ADD TO CART”. • If the selected variant is out of stock, display only “COMING SOON”. Because I want the correct state rendered on first load and to change instantly when a shopper switches variants, the solution has to live entirely in server-side Liquid. JavaScript work-arounds aren’t acceptable for this task. Deliverable – Updated Liquid markup/snippets (likely within product or section file) that conditionally renders a single button per the rules above and remains theme-update friendly. Acceptance – Refreshing the page on any default variant shows the right button immediately. ...

What I Need ### Logo System I need an **icon + wordmark** combination that works as a complete system. The icon must also function as a standalone mark.

    US Senior Software Engineers Needed
    S&#039;est terminé left

    I’m expanding our engineering roster and want to meet seasoned, US-based developers who thrive on production-grade challenges. Your background should include at least five years in professional software development, with deep, hands-on fluency in both JavaScript and Python. An advanced track record with React (6 + years) is especially important because many of our user-facing projects lean on this library for rich, responsive interfaces. If you enjoy pairing modern JavaScript (React on the front end, Node.js on the back end) with cloud-native services, collaborating across product, design, and DevOps, and ultimately owning features from planning through deployment, we’ll get along well. Our stack also touches Go, C#/.NET, and Spring Boot micro-services, so polygl...
