Shopify Theme Update & Optimization

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.
