I need a Shopify developer who can jump in quickly, refresh my store’s theme, and leave every existing customization intact. The current theme is a few versions behind; I’d like it updated without wiping out the tweaks I already paid for—custom sections, app hooks, and liquid edits all have to stay. Scope of work (lean and focused): • Install the newest theme version and migrate current custom code so nothing breaks. • Configure bulk-pricing logic so discounts show on product and cart pages. • Hook up a small REST-based API that feeds real-time stock data to the storefront. • Tidy up any layout glitches that appear after the upgrade. I’m aiming for fast turnaround and budget-friendly hourly help, so concise solutions and clear communication matter. If you’ve handled theme upgrades, API integrations, and complex pricing in Shopify before, let’s get started right away.
