    Several minor fixes and enhancements remain on my Shopify store, and I’d like to hand them off to a developer who is comfortable jumping in for quick, focused tasks. Work will be assigned in small batches—sometimes a bit of Liquid or CSS to adjust the theme, other times a short script, a settings tweak, or an app install. Typical tasks could include: theme section adjustments, minor layout refinements, error troubleshooting, Shopify API or app integrations, and checkout flow polish. No large redesigns right now—just precise, clean updates that keep the store humming. Solid knowledge of Liquid, HTML, CSS, JavaScript, and the Shopify admin is essential. Please tell me your usual process for small Shopify changes and note any time-zone constraints ...

    I’m refreshing my iOS app from the ground up and need a designer who can own both the product experience and the visual identity. What I already have – A rough colour scheme and preferred typefaces that I’m happy to keep. – No finished logo and no complete style guide. What I need from you The complete screen-by-screen design of the app, shaped for iPhone devices and aligned with Apple’s Human Interface Guidelines, plus a distinctive logo that ties everything together. The emphasis is on three things: a clean interface layout, an intuitive user-flow, and cohesive branding.

    Hi, I'm looking for someone to help continue development on an existing web application. The project was originally built in React and we've been migrating it to Next.js. Unfortunately, the previous developer couldn't finish the migration before leaving the project, so there are still a number of incomplete areas that need to be cleaned up. Nothing is in terrible shape, but there are quite a few loose ends. Some UI sections disappeared during the migration, a few pages aren't behaving as expected, and the overall user experience could use another round of polishing. I'm looking for someone who enjoys working on an existing product rather than starting from scratch. Some of the things we'll probably work on together include: Restoring UI components...
