I have four live stores—two on Shopify and two on WooCommerce—that need 13 specific fixes. The work spans classic bug squashing, pinpointing and cleaning up template issues, and sharpening the UI so every page looks polished. Key focus areas • Bug fixes that eliminate current errors without introducing new ones • Template debugging to tidy up theme code and liquid/PHP logic • UI improvements that keep style consistent across all themes • Full responsiveness on mobile, tablet, and desktop, with extra attention to the checkout flow and product pages You will be the only developer touching the codebase, so stability is critical. Every change must be tested thoroughly. You’ll return clean, well-commented code, notes on what changed, and confirmation that the updates passed device and browser checks. Detailed brief will be shared before onboarding. Meet the agreed deadline, keep communication clear, and we’ll move fast—without sacrificing quality.
