About this gig
Most Shopify experts fix symptoms.
I diagnose why your store is silently losing revenueand eliminate it at the root.
You're not here because everything is working.
You're here because something is breaking, slowing, conflicting, or costing you money.
And thats exactly where I operate.
WHAT I ACTUALLY DO:
- Hidden JavaScript conflicts killing conversions
- Broken Liquid logic affecting product, cart, or checkout flow
- App collisions slowing down your store or breaking features
- Payment gateway failures silently blocking transactions
- UX friction points that reduce add-to-cart and checkout rates
- Theme limitations that require true custom engineering
CORE SERVICES:
- Shopify bug fixing (theme, checkout, cart, product pages)
- Deep custom coding (Liquid, JavaScript, Shopify APIs)
- Payment gateway integration & debugging (Stripe, PayPal, local gateways)
- Shopify 2.0 theme fixes & upgrades
- App conflict resolution & script optimization
- Checkout & cart error fixing
- Custom feature development
- API & webhook debugging
- Mobile responsiveness fixes
- Conversion leak detection & repair
You need someone who understands how every technical issue connects to revenue.
That's what I bring DM TODAY!!!!!!!

FAQ
Can you fix issues caused by multiple apps conflicting?
Yes, this is one of the most common hidden problems. I trace script injections, isolate conflicts, and restructure execution so your store runs cleanly without breaking features.
Can you handle complex payment gateway integrations or failures?
Absolutely. I debug API responses, webhook flows, and checkout logic to ensure transactions complete reliably.
Do you just fix the issue or also optimize performance?
Both. Every fix is implemented with performance in mind so your store becomes faster, not heavier.
Do you work with custom-coded Shopify themes?
Yes. Whether it’s a heavily modified theme or fully custom build, I can analyze and fix the structure safely.
Can you identify problems I’m not aware of?
Yes that’s part of my process. I often uncover hidden issues affecting speed, UX, and conversions.
What if the issue comes back after a theme or app update?
I build fixes that are update-resilient, and I can guide you on how to prevent future breakage.
How fast can you resolve urgent issues?
Critical bugs (like checkout failures) are prioritized and can often be resolved within hours depending on complexity
