About this gig
Need an experienced software engineer to handle custom Liquid coding, theme modifications, or technical bug fixes on your Shopify store?
Most Shopify store owners run into strict template limitations. I write clean, custom Liquid, HTML5, modern CSS, and JavaScript to deliver custom functionality, pixel-perfect layouts, and high-converting storefront experiences.
What I Do:
Custom Liquid theme programming and reusable JSON sections
Figma, XD, or PSD to custom Shopify theme conversion
Bug fixes: layout breaks, cart drawer issues, mobile responsiveness
Custom JavaScript interactions, mega menus, and product variant selectors
Third-party API integrations, webhooks, and private app connections
Store speed optimization and Core Web Vitals cleanup
Why Choose Me?
Computer Science Engineer (BSc, BRACU)
100% clean, modular code that does not break future theme updates
Fast turnaround with clean Git version control
Direct communication and unlimited revisions
Please message me before placing an order so we can inspect your store code and discuss requirements!
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.
