Hire Shopify Developers to Grow Your Store

Bring in Shopify engineers who customise themes in Liquid, build private apps and checkout extensions, and migrate stores without losing SEO or order history.

Shopify skills that go past the theme editor

Shopify handles hosting, payments and security, which lets brands focus on selling. Growth eventually brings needs the theme editor cannot cover: custom product configurators, subscription logic, B2B pricing, ERP syncing or a checkout that reflects how you really sell. Those need a developer who knows Liquid, the Admin and Storefront APIs and Shopify's app ecosystem.

D2C brands, retailers moving from WooCommerce or Magento, and agencies with Shopify clients hire our developers. Some need theme work and conversion improvements. Others need custom apps, Shopify Functions or a headless storefront on Hydrogen. We confirm the type of work first, since theme specialists and app developers are different profiles.

Our Shopify developers use theme version control, development stores and preview links so nothing goes live untested. They keep app usage lean to protect page speed and monthly costs. Nexzem takes care of contracts, NDA and replacement, while your team keeps control of the store and every line of custom code.

Shopify developers for custom themes, apps, Plus checkout extensions, headless Hydrogen stores and store migrations.

  1. 01

    Custom Online Store 2.0 themes

    Fast, section-based themes built from your designs in Liquid, with metafields and dynamic sources so merchandisers can manage content without code.

    Private and public apps

    Shopify apps using the Admin API, webhooks and App Bridge for inventory sync, custom fulfilment, loyalty or reporting needs specific to your business.

  3. 03

    Checkout UI extensions and Shopify Functions for discounts, delivery rules and payment customisation on eligible plans, replacing fragile script workarounds.

  4. 04

    React-based Hydrogen storefronts on the Storefront API for brands that need unusual layouts, content-heavy pages or multi-region experiences.

  5. 05

    Store migration

    Moving products, customers, orders and redirects from WooCommerce, Magento or custom platforms, with URL mapping that protects search rankings.

  6. 06

    ERP and marketplace integrations

    Two-way syncs with ERPs, warehouse systems, accounting tools and marketplaces so stock and orders stay accurate across channels.

  7. 07

    Speed and conversion fixes

    Removing unused apps and scripts, optimising images and Liquid loops, and improving product and cart pages based on analytics data.

Why hire Shopify Developers through Nexzem

  • Theme or app specialist, as needed

    We screen separately for Liquid theme skills and app development, so the developer matches the work you actually have.

  • Trial on a development store

    Start with a short trial on real tickets in a development or preview theme before continuing the engagement.

  • Coverage for sale periods

    Overlap hours and flexible capacity let you add developers ahead of seasonal sales and launches, then scale back.

  • Your store, your code

    Developers work as collaborators on your store under an NDA if required, and all custom themes and apps are your IP.

  • Replacement without disruption

    If a developer has to leave, we provide a replacement with a documented handover of themes, apps and integrations.

How to vet a Shopify developer

Shopify developers range from theme customizers to engineers who build custom apps and headless storefronts. Clarify which you need, then check real skills: Liquid and Online Store 2.0 sections, metafields and metaobjects, the Shopify CLI and GitHub workflow, theme app extensions, the Admin GraphQL API, webhooks and Shopify Functions for discounts, shipping and checkout logic.

Performance and conversion awareness separate strong developers from average ones. Ask how they kept stores fast while adding features, how they audited apps that slowed pages down and how they measured the effect of changes on conversion. Experience migrating stores without losing URLs and rankings is valuable for brands moving from other platforms.

For larger merchants, ask about Shopify Plus features such as checkout extensibility, B2B and multiple expansion stores, and about integrations with ERPs and warehouses. Our Shopify development page outlines the practices we follow on client stores. Ask for a store where they handled a high-traffic sale.

  • Builds themes with sections, blocks and metafields.
  • Develops custom apps with the Admin GraphQL API.
  • Uses Shopify Functions and checkout extensibility correctly.
  • Keeps stores fast while adding features.
  • Has migrated stores without losing search rankings.
  • Integrates Shopify reliably with ERPs and warehouses.
  • Uses Git-based theme workflows and preview themes.

Interview questions we use for Shopify developers

Our questions reflect what merchants actually ask for: custom features, speed, integrations and migrations. Candidates walk through stores they built, explain how they implemented specific features and review a theme snippet or app integration with us, discussing performance and maintainability trade-offs.

Good answers prefer native Shopify features and well-built apps over fragile workarounds, consider page speed in every decision and treat checkout and payment flows with particular care. We also look for clear communication with merchants, who often need technical options explained in business terms.

  • How would you build a product bundle with tiered discounts?
  • How do you store structured product data, such as specifications or ingredients?
  • How do you find which apps or scripts are slowing a store down?
  • How would you sync inventory between Shopify and an ERP reliably?
  • What changes when a store moves to checkout extensibility?
  • How do you migrate a store from WooCommerce without losing SEO?
  • How do you test theme changes before publishing them?

Onboarding a Shopify developer in the first two weeks

In week one, the developer reviews the theme code, installed apps, integrations and analytics, and sets up a development store and theme workflow connected to Git. They document apps that overlap or slow the store, identify quick performance wins and fix small issues the merchant has reported.

In week two, they deliver a scoped feature or improvement, reviewed on a preview theme before publishing. Merchants still choosing a platform can read our Shopify vs WooCommerce comparison, and brands considering a custom storefront can learn about headless commerce first.

Hiring Shopify Developers: from first call to first commit

    Talk through your store and roadmap with candidates and choose the best fit.

  4. Stage 4

    Collaborator access and trial

    Grant collaborator access and the developer starts real work in a safe preview theme.

  5. Stage 5

    Grow together

    Continue monthly, adding developers before peak periods and reducing afterwards.

Where Shopify Developers make a difference

  • Custom theme for a growing brand

    A direct-to-consumer brand outgrows its purchased theme and adds a Shopify developer who builds a custom Online Store 2.0 theme with flexible sections, faster pages and structured product content the marketing team can manage.

  • Replacing several apps with one custom app

    A store running many overlapping apps gets a developer who replaces them with a single custom app and theme app extension, reducing monthly fees, removing conflicting scripts and improving page speed noticeably.

  • ERP and warehouse integration

    A merchant shipping from its own warehouse integrates Shopify with its ERP and warehouse system, with a developer building reliable syncing for orders, stock and fulfillment status, plus alerts when anything fails.

  • Migration from another platform

    A brand moving from WooCommerce or Magento gets a Shopify developer who migrates products, customers and orders, maps old URLs to new ones and verifies tracking, so sales and rankings continue smoothly after launch.

Hiring Shopify Developers: FAQs

Something else on your mind? Ask a consultant and get a reply within one business day.

How much does it cost to hire a Shopify developer?

It depends on whether you need theme work, app development or headless skills, along with seniority and engagement length. We bill monthly per developer after a short trial, and confirm pricing after a free consultation.

Do I need Shopify Plus for custom checkout work?

Some checkout customisation is limited to Shopify Plus. Our developers will explain what is possible on your plan and suggest alternatives where needed.

Can you migrate my store from WooCommerce or Magento?

Yes. We migrate products, customers, order history and URLs, and set up redirects so you keep your search visibility.

Will custom work slow down my store?

Our developers keep code lean and avoid unnecessary apps. They test speed before and after changes so performance is protected.

Who owns custom apps built for my store?

You do. All custom themes, apps and integrations are your IP, and we sign an NDA on request.

Can a Shopify developer build a private app just for our store?

Yes. Developers build custom apps for a single store using Shopify's APIs, webhooks and extensions, for needs such as ERP syncing, custom pricing rules or internal workflows. Custom apps avoid paying monthly fees for public apps that do much more than you need, and keep your store lean.

Will a Shopify developer work with our existing agency or designer?

Yes. Developers can implement designs from your agency or in-house designer, follow their brand guidelines and work within their project process, focusing on clean theme code, performance and the technical features the design requires, raising concerns early when a design would hurt speed.

We work with clients across the USA, UK, Australia, UAE, New Zealand and India.
