Built a conditional variant switch on Shopify in under an hour. A client needed one specific variant (55 Gallon Drum) on their product page to show a "Contact for Pricing" button instead of Add to Cart. The other 4 variants had to keep working exactly as they were. Wrote a scoped Liquid + JavaScript solution that detects the selected variant and swaps the CTA dynamically. No plugins, no theme-breaking changes, no impact on the rest of the store. Client's words: "Extremely well to work with. Fixed the issues without haste. Exceeded my expectations!"
