I will build a custom shopify app or discount function
Ayoub A.
About this gig
Need a feature your theme or the App Store can't give you? I build custom Shopify apps and Functions that do exactly what your store needs, tested before they reach your customers.
What I build:
- Discount Functions: quantity breaks, tiered and bundle discounts, BOGO, customer-specific pricing
- Checkout and Thank you page extensions, post-purchase upsells
- Theme app blocks: product page widgets, cart drawers, free-gift and rewards bars
- Admin apps with Polaris: settings pages, dashboards, bulk tools
- Integrations with your ERP, CRM or any REST/GraphQL API
Why work with me:
- I've built four Shopify apps from scratch: quantity breaks, cart drawer, bundles and post-purchase upsell
- Clean TypeScript, Functions in Rust or JavaScript, tested on real checkouts
- A clear written plan before I start, and updates at every step
- You own the code: I hand over the repository and a setup guide
Send me a message with what you need and I'll reply with a scope and a fixed quote.

FAQ
Do I need a Shopify Plus plan?
It depends. Theme app blocks, admin apps and Thank you page extensions work on every plan. Custom apps that include Shopify Functions need Shopify Plus, so I check your plan before quoting and suggest the best option.
Will the app slow down my store?
No. Storefront code stays small, loads after your theme and is checked with Lighthouse. Discount logic runs inside Shopify's checkout, not in the shopper's browser.
Do I own the code?
Yes. You get the full repository, deployment steps and a setup guide, and the app is created under your own Shopify account.
Can you fix or extend an existing app?
Yes, if you can share the repository. I review the code first and confirm the scope and price before I start.
