Hire a Shopify App Developer — Private & Public App Builds
Custom Shopify app development for merchants and product teams. Private apps that solve one specific problem in your store, or full Shopify App Store submissions with OAuth, billing API, and Polaris-native admin. Built with Node, Remix, and the modern Shopify app stack.
Sound familiar?
No app on the App Store does exactly what you need
You've tried 5 different apps, each solving half the problem. Manual workarounds and Zapier chains are eating your team alive. Time to build the right one once.
Apps are quietly killing your store's speed
Third-party apps inject scripts on every page, creating load time nightmares and unpredictable conflicts. A custom Shopify app loads only where it's needed — and only what's needed.
Vendor lock-in is costing you thousands per year
Monthly subscription fees for features that should be built once and owned permanently. A custom Shopify app typically pays for itself in 6-12 months versus app stack fees.
Everything included
No hidden extras. No scope creep. Clear deliverables agreed upfront.
Private Shopify App Development
Custom apps built for your store only — no App Store submission needed. Solve one specific workflow problem, own the code, no monthly fees.
Public App Store Submissions
Full Shopify App Store submissions with OAuth flow, GDPR webhooks, billing API integration, and Partner-approved code. End-to-end including listing assets.
Polaris-Compliant Admin UI
Native-feeling admin interfaces using Shopify Polaris React components. Merchants feel like the app is part of Shopify, not bolted on.
Theme App Extensions & App Blocks
Storefront integrations that load fast and stay in sync. App Blocks and Theme App Extensions instead of legacy script tags.
Reliable Webhook Processing
Webhook handlers with retry logic, idempotency keys, and event tracking. Order events, inventory updates, customer actions — handled reliably at scale.
Third-Party API Integration
Connect your Shopify app to ERPs (SAP, NetSuite), CRMs (HubSpot, Salesforce), fulfilment (ShipBob, Linnworks), or payment gateways via Admin API + webhooks.
From brief to launch
Requirements Scoping
We define exactly what the app needs to do, the API surfaces it will touch, and the data flows involved. I deliver a scope doc before any code is written.
Architecture + Setup
I scaffold the app using Shopify CLI with the correct app type (embedded, public, private) and set up the dev environment.
Build + Iteration
Weekly progress demos so you can test features in real time and catch requirement gaps early — not at the end.
Review + Launch
Full code review, security audit, and App Store submission support if required. Post-launch monitoring included.
Real results, real clients
AWH Ekken — Whitelabel Dealer Portal (Multi-Tenant Shopify App)
Built a full-stack Shopify embedded app giving each dealer their own branded storefront on a custom domain, with per-dealer pricing rules, a self-service quote system, and end-to-end order tracking.

View case study →"Working with Abdul on our custom Shopify Dealer Portal app was a great experience. He handled the entire development, from architecture to deployment, with a very professional and structured approach. The app included dealer management, automated workflows, custom pricing, and integrations with Shopify. Abdul was proactive, communicated clearly, and consistently delivered high-quality work. The final product exceeded expectations and is now running smoothly in production. I would definitely recommend him for any complex Shopify app or automation project."
"Last week, I reached out to Abdul with a complex Shopify case that I needed to be handled urgently. I had a very tight deadline, and he delivered everything on time. The task involved converting the shopping cart into a quotation cart without using any plugins, which he executed perfectly. He understands Shopify deeply and knows how to work around its constraints without compromising quality."
Questions before you commit
Yes — I handle the full submission process including app listing copy, store listing screenshots, App Store review preparation, and addressing any feedback from the Shopify review board.
Private apps are built for a single store and are not listed in the App Store. Public apps can be installed by any Shopify merchant and require OAuth, billing API integration, and App Store approval.
Yes — I offer monthly retainer plans for ongoing app maintenance, version upgrades as Shopify updates its APIs, and new feature development. Most app clients move to a retainer after launch.
Admin GraphQL API, REST Admin API, Storefront API, Customer Account API, Payments Apps API, and Checkout Extensibility. I select the right API surface based on what your app needs to do.
Shopify releases new API versions quarterly and deprecates old ones. I build apps with version management in mind and can handle the upgrade cycle as part of a maintenance retainer.
Yes — multi-store apps use Shopify's OAuth flow so merchants install from their own admin. I build the multi-tenancy architecture from scratch, including session management and per-store data isolation.
Yes — Shopify Functions allow custom discount logic, payment customisations, and shipping rules that run directly on Shopify's infrastructure. I use Functions wherever native checkout logic customisation is required.
Need a custom Shopify app built by a senior developer?
Book a 30-min scoping call. I'll tell you whether your idea needs a private app, a public App Store submission, or just better use of existing Shopify features — and what each option costs.
No commitment. No sales pitch. Just a real conversation about your project.
