Fix Shopify Bugs | Shopify Theme Customization | Shopify Custom Coding
Are Shopify bugs, theme errors, broken layouts, or slow performance hurting your store's sales?
Most store owners lose customers to small issues they never notice broken sections, checkout errors, mobile display problems, and theme conflicts that quietly hurt the shopping experience.
I fix Shopify issues at the root cause and build custom features using Liquid, HTML, CSS & JS not quick patches that break again.
Working with me means a stable, fast, professional store your customers can actually shop on without errors.
WHAT I PROVIDE:
- Bug fixes & error resolution
- Theme customization (any theme)
- Custom coding: Liquid, HTML, CSS, JS, AJAX
- Custom sections & blocks from scratch
- Mobile & responsive design fixes
- Cart, checkout & payment fixes
- Speed & performance optimization
- GA4 & Facebook Pixel setup
WHY CHOOSE ME:
- Root-cause fixes, not patches
- Works with Dawn, Impulse, Turbo & custom themes
- Clean, commented, editable code
- Live store never touched without approval
- Fast delivery, clear communication
Message me your issue - I'll review it and tell you honestly how to fix it and how to fix it and how long it.

FAQ
What Shopify services do you provide?
I provide complete Shopify bug fix, Shopify theme customization, Shopify custom coding using Liquid, HTML, CSS, JavaScript, and AJAX. I also handle speed optimization, GA4 & Facebook Pixel setup, mobile responsiveness fixes, and custom section/block development.
Will my live Shopify store be affected during the work?
No never. I always work on a duplicate/backup theme first. Your live store stays fully active and untouched. I only push changes live after you review and give approval.
Which Shopify themes do you work with?
I work with all Shopify themes free themes like Dawn and Debut, premium themes like Impulse, Turbo, Prestige, and Debutify, and fully custom-built themes. No theme is too complex for me.
How quickly can you fix my Shopify bug?
Most Shopify bug fixes are delivered within 24 hours. For complex Shopify theme customization or custom coding projects, delivery is 2–3 days depending on the scope. I always deliver on time.
Can you match my existing store's design and branding?
Absolutely. Before making any Shopify customization, I study your store's fonts, colors, spacing, and layout style. Every change I make looks like it was always part of your original design.
What if my issue is more complex than one package covers?
Message me before ordering I'll analyze your Shopify issue for FREE and recommend the right package. No surprises, no hidden costs after you pay.
Do you provide Shopify speed optimization?
Yes. I identify and fix performance bottlenecks unused scripts, render-blocking code, unoptimized images, and slow app conflicts — to improve your Shopify store's page speed and Google PageSpeed score.
Can you build a custom Shopify section from scratch?
Yes. I build fully custom Shopify Liquid sections with schema settings, responsive design, and theme editor controls — so you can easily edit content without touching any code after delivery.
Do you need my Shopify admin access or password?
I only need Collaborator Access — not your login or password. I'll send you a simple step-by-step guide to share it in 2 minutes. You can remove my access anytime.
