Shopify & Shopify Plus Developer
I was the Senior Developer who migrated Culture Kings from Magento to Shopify Plus, one of the first and later one of the biggest Shopify Plus stores in the Asia Pacific region. That migration taught me what actually holds up at scale on Shopify Plus and what quietly falls over. Since going freelance I have built and maintained Shopify and Shopify Plus stores for brands like Beginning Boutique, working with clients across Brisbane, Sydney, Melbourne, and the rest of Australia. If you are moving onto Shopify Plus, outgrowing your current build, or stuck with an agency that put juniors on your store, we should talk.
What I build with Shopify
Shopify Plus Migrations
Moving from Magento, WooCommerce, BigCommerce, or a legacy custom build onto Shopify Plus. I ran the Magento to Shopify Plus migration at Culture Kings, so I have already made most of the decisions your migration will need: what to rebuild versus rehome, how to preserve URLs and SEO equity, how to move customers and order history without breaking reporting, and how to cut over without a dark weekend.
Checkout Extensibility & Shopify Functions
Shopify has retired checkout.liquid, and scripts have to be rebuilt as Shopify Functions and checkout UI extensions. This is where a lot of Plus stores are currently stuck. I build custom discounts, payment and delivery customisations, validation rules, and checkout UI extensions properly, so your checkout logic survives the platform moving underneath it.
B2B & Wholesale on Shopify
Trade portals, company accounts, customer-specific catalogues, contract and tiered pricing, quote workflows, and net payment terms. B2B on Shopify has come a long way, but it still needs real engineering to match how a wholesaler actually trades. See my B2B eCommerce development work.
ERP, Accounting & Marketing Integrations
Your store is only as good as the systems behind it. I connect Shopify to Xero, NetSuite, MYOB, Klaviyo, and the rest of your stack, with retries, idempotency, and monitoring designed in rather than bolted on. Browse all integrations.
Headless Shopify
Build your own storefront on the GraphQL Storefront API or Hydrogen, and let Shopify handle checkout, payments, and compliance. Headless is the right call less often than agencies pretend, so I will tell you honestly whether your store actually needs it before quoting the work.
Scale & Peak Traffic
Shopify Plus is built for high-volume trading, but a store still fails under load if the theme, apps, and integrations are careless. Culture Kings ran drops that would flatten most stores. I build for the sale day, not the quiet Tuesday.
Custom Themes & Storefronts
Custom Liquid themes built for your brand and your merchandising, not a marketplace template with the colours swapped. Fast, accessible, and easy for your team to run day to day without calling a developer for every change.
Advanced Shopify Plus Features
Suited for medium to large businesses, Shopify Plus allows for advanced eCommerce functionality such as Third-party calculated shipping rates, Expansion stores for multiple languages or currencies, Advanced eCommerce Reporting, Advanced Promotions, Customised Checkouts, Tax automation, Bot protection and more.
Dedicated Support
With any medium to large eCommerce business comes the need to be able to rely on your eCommerce provider, Shopify Plus users benefit from priority customer support. This means faster response times and dedicated assistance from the Shopify support team, ensuring that any issues or concerns are addressed promptly.
Security and Compliance
Shopify takes care of security and compliance, including PCI DSS compliance for handling credit card transactions. This allows you to focus on growing your business without worrying about the technical aspects of security.
Shopify Omnichannel eCommerce
Shopify allows for seamless integration with various sales channels, including social media platforms and marketplaces. This enables your eCommerce brand to reach a broader audience and maximise sales opportunities.
Ongoing Support & Maintenance
The same developer who builds your store keeps looking after it. App updates are reviewed against your theme and tested rather than bulk-applied, and Shopify platform changes are handled before they break something. Most of my clients have stayed with me for five to seven years. Optional website maintenance plans are available.

Senior Shopify Plus work. None of the agency layers.
Your current agency
Senior names on the proposal. Juniors on the code.
-
Junior and intermediate developers write your Liquid, JavaScript, and Shopify Plus customisations, loosely supervised by the senior who is too busy and the sales team who sold the project.
-
Communication is routed through account managers who filter what gets asked and what answer you receive.
-
Architectural decisions about apps, integrations, and checkout flows are made in meetings by people who never open your storefront codebase.
-
Work is scoped by people who won't be writing the code, and the actual build gets handed down to juniors still learning Shopify Plus on your store.
-
After launch, you are handed to a maintenance team you have never spoken to and have to re-explain the store.
-
“Maintenance” means automated bulk app updates pushed without reviewing changelogs or testing compatibility with your theme.
Working with me
The senior on the proposal is the one writing the code.
-
I am the senior. I write every line of your Shopify code personally, from theme through to checkout extensions and Shopify Functions.
-
You talk to me directly. No account manager filtering questions on the way in or answers on the way back.
-
Architecture and trade-offs are decided by the person implementing them. The thinking and the typing happen in the same head.
-
I scope it, design the architecture, and write the code myself. I have already shipped on Shopify Plus at scale at Culture Kings, so the decisions are made by someone who has made them before.
-
The same developer who built it stays with you. Most of my clients have been around for five to seven years.
-
Each update is reviewed against your store, tested in a preview environment, and logged. No silent breakage two weeks after the invoice.
You’re in good company

Common Shopify Project Questions
What's the difference between Shopify and Shopify Plus?
Shopify Plus is Shopify's enterprise tier. The storefront is much the same, but Plus adds the things larger merchants actually need: checkout customisation through Shopify Functions and checkout UI extensions, higher API rate limits, expansion stores for multiple regions or brands, B2B company accounts and catalogues, Shopify Flow automation, and a dedicated support path. If you are only after a nicer theme, you do not need Plus. If you are hitting the ceiling on checkout logic, API limits, wholesale, or multi-store, that ceiling is exactly what Plus removes.
Is Shopify Plus worth it for my business?
Honestly, not always. Plus is worth it when you are constrained by the platform rather than by your team: you need custom checkout logic, you are running wholesale alongside retail, you need expansion stores, or your order volume is pushing API limits. If none of those are true, standard Shopify plus good engineering will usually get you further for less money. I would rather tell you that up front than sell you an upgrade you do not need.
What does a Shopify Plus migration involve?
Roughly: audit what you have, decide what is worth rebuilding versus retiring, then move data (products, customers, order history), rebuild the storefront, rebuild any checkout logic as Shopify Functions, reconnect your ERP, accounting, and marketing integrations, map every old URL to a new one so you keep your search rankings, and cut over. The parts people underestimate are order history, customer-specific pricing, and the redirect map. I ran this migration at Culture Kings from Magento, so I plan for those from day one.
Why hire a freelance Shopify Plus developer instead of an agency?
With an agency you usually meet a senior in the pitch and get a junior on the code. With me, the person who quotes the project is the person who writes every line of it, makes the architectural calls, and is still there in three years when something needs changing. You also skip the account manager sitting between your question and the answer. The trade-off is honest: I am one person, so I take on fewer projects at a time and I am not the right fit if you need a large team mobilised next week.
Can Shopify integrate with Xero, NetSuite, or MYOB?
Yes, and this is a large part of what I do. Off-the-shelf connector apps handle the happy path and then quietly fall apart on partial refunds, multi-currency, surcharges, or customer-specific pricing. I build integrations with retries, idempotency, reconciliation, and monitoring so failures get caught before they become an accounting problem. See the Xero, NetSuite, and MYOB integration pages.
Do I need to rebuild my checkout now that checkout.liquid is gone?
If you were using checkout.liquid or Checkout Scripts, then yes. Shopify has retired both in favour of checkout extensibility, which means custom checkout behaviour now has to be rebuilt as Shopify Functions and checkout UI extensions. In practice that covers custom discounts, payment and delivery method customisation, validation rules, and anything you had scripted at checkout. It is a genuine rebuild rather than a config change, but the result is far more durable because it no longer breaks every time Shopify updates the checkout.
