Hire Shopify Developers for Themes, Apps and Store Changes
RED SAG provides dedicated Shopify developers from our team in Tamil Nadu, India, to merchants, e-commerce managers and digital agencies in the USA, UK, Australia, Canada and India. They work on your theme code, build custom apps and extensions, and handle the steady stream of store changes that a growing brand generates.
Shopify work is broader than it looks. One week it is a new product page section in Liquid, the next a discount rule written as a Shopify Function, a checkout UI extension, or a sync with your ERP or warehouse. We assign developers who understand the platform's limits, especially what can and cannot be changed in checkout, so you do not pay for work that Shopify will not allow.
Agencies can use our Shopify developers white-label under NDA, working in your Partner account and project tools. Merchants can hire full time, part time or by the hour, or get a fixed quote for a defined build such as a theme customisation. Every engagement can begin with a one-week paid pilot.
What our Shopify developers build for you
Custom Online Store 2.0 themes
Themes built or customised in Liquid on top of Dawn or a premium theme, with sections and blocks that merchandisers can rearrange in the theme editor without calling a developer.
Custom and public apps
Embedded admin apps built with Shopify's Remix app template, Polaris and App Bridge, using the GraphQL Admin API and webhooks, with session storage and billing set up correctly.
Checkout and discount logic
Checkout UI extensions, Shopify Functions for discounts, payment and delivery customisation, and post-purchase offers, replacing older checkout.liquid and Script Editor customisations.
Headless storefronts with Hydrogen
Custom storefronts on Hydrogen and Oxygen, or Next.js with the Storefront API, for brands whose content, performance or design needs go beyond what a theme can do.
Integrations and data sync
Connections to ERPs, inventory and warehouse systems, marketplaces and CRMs using bulk operations, webhooks and metafields, with rate limits and retries handled instead of ignored.
Migrations and speed work
Moves from WooCommerce, Magento or BigCommerce with products, customers and redirects mapped, plus theme performance clean-ups that remove unused app scripts and heavy Liquid loops.

Junior, mid-level or senior
Pick the level that matches the work. Many teams pair one senior developer with a junior or mid-level developer to keep costs down without losing review quality.
Junior
1–3 years
Handles theme edits and store tasks with clear specs, reviewed by a senior developer.
- Build and adjust Liquid sections and blocks from designs
- Configure metafields, templates and navigation for new collections
- Fix layout and cross-browser issues on product and cart pages
- Keep theme changes in Git and test them in a preview theme first
Mid-level
3–6 years
Delivers theme features and small apps independently and understands app and API limits.
- Build custom apps and theme app extensions on the GraphQL Admin API
- Write Shopify Functions for discounts or delivery rules
- Integrate third-party apps and remove the ones that slow the store down
- Estimate work and flag what Shopify's platform does not allow
Senior
6+ years
Plans complex builds such as headless storefronts, Plus checkout work and large migrations.
- Architect Hydrogen or other headless storefronts and their content model
- Plan migrations off checkout.liquid and Shopify Scripts
- Design ERP and warehouse integrations that respect API rate limits
- Review other developers' theme and app code and set standards
Common Shopify problems our developers avoid
Editing the live theme directly
Changing code in the published theme means a typo can break the store during a sale. Our developers work on a duplicate or Git-connected theme, share a preview link and publish only after you approve.
Solving everything with another app
Stacking apps for small features adds monthly fees and scripts that slow every page. We check whether a section, metafield or Function can do the job before recommending another subscription.
Building on deprecated checkout methods
Shopify has been retiring checkout.liquid and Script Editor in favour of Checkout Extensibility and Functions. New checkout work is built on the supported extension points so it does not need rebuilding later.
Ignoring API rate limits
Syncs that fire one REST call per product hit Shopify's limits and fail quietly on large catalogues. We use GraphQL bulk operations, respect cost-based throttling and log every failed sync.
Ways to hire
Four ways to work with our Shopify developers, and when each one makes sense for Shopify work.
Full-time dedicated developer
One developer works only on your product, around 160 hours a month, inside your tools and sprint rhythm.
Best for brands and agencies with a constant flow of Shopify work: campaigns, new sections, app changes and integrations every week.
Fixed monthly fee, invoiced monthly
Part-time dedicated developer
The same developer every week for about 80 hours a month, usually half days or agreed days.
Suits a merchant with a stable store that needs regular tweaks, seasonal landing pages, app updates and quick fixes.
Fixed monthly fee for the agreed hours
Hourly
Pay only for tracked hours against tickets you raise. Hours and task notes are shared with every invoice.
Good for a speed audit, fixing a broken app integration, a small checkout change or an agency's overflow tasks.
Tracked hours, invoiced monthly
Fixed-price project
A written scope, a fixed quote and milestones. We carry the estimate risk; changes are quoted before they are built.
Works for a theme build from approved designs, a store migration, or a custom app with an agreed feature list.
Milestone payments against an agreed scope
Indicative rates for Shopify developers
Rates by seniority for hourly, part-time and full-time dedicated work. Choose the currency you pay in.

How we vet and assign Shopify developers
Technical interview
A senior engineer on our side interviews every developer on the stack you are hiring for, covering the topics listed on this page, before they are put forward to any client.
Review of real work
We read code the developer has written, from our own projects or their earlier work, looking at structure, naming, tests and how they handle errors, not just whether it runs.
Practical trial task
A short task in the same stack, done in a real repository and reviewed like a pull request. It shows how someone works, asks questions and writes up what they did.
Matched to your brief
We put forward the developer whose experience fits your product and time zone, share a short profile, and you interview them yourself before anything is signed.
What the Shopify interview covers
- Liquid objects, filters and render performance, and how sections and blocks are structured in Online Store 2.0
- What Checkout Extensibility and Shopify Functions can and cannot change
- Using the GraphQL Admin API, webhooks and bulk operations within rate limits
- Metafields and metaobjects for structured product and content data
- Theme workflow with Shopify CLI, Git and preview themes
The trial task
Build an Online Store 2.0 section for a product page that reads a metaobject (for example a size guide), is fully editable in the theme editor and passes Theme Check, plus a short script that updates metafields for a list of products through the GraphQL Admin API. We review the code, the preview theme and the write-up.
How onboarding works
- 01
Call and NDA
A short call about your product, stack and team. We sign your NDA, or ours, before you share code, designs or business details.
- 02
Profile and interview
We share the profile of the developer we recommend and you interview them. A match usually takes about a week, depending on availability.
- 03
Contract and IP
The contract assigns all code and work product to you once invoices are paid, and sets out rates, hours, notice and confidentiality.
- 04
Access through your tools
You invite the developer to your GitHub or GitLab, Jira or Linear, and Slack or Teams. You control access and can revoke it at any time.
- 05
Updates you can rely on
A written update at the end of every working day, a weekly summary with hours, what shipped and what is blocked, and a demo when you want one.
The developer's first week
- Get collaborator or staff access and set up a Git-connected development theme
- Review installed apps, theme code, metafields and any custom apps or scripts
- Complete a small live-store task through your approval process
- Share a written note on performance issues, risky customisations and quick wins
Working hours overlap
Our team is in India (IST, UTC+5:30). These are the overlap windows we plan around; the exact hours are agreed in the contract.
United Kingdom
Our normal day (9:00–18:00 IST) covers roughly 9:00 am to 12:30 pm in London in winter and 9:00 am to 1:30 pm in summer. A developer working 11:00–20:00 IST can cover until about 2:30 pm GMT.
USA and Canada (Eastern)
On a shifted schedule the developer is online for about 9:00 am to noon Eastern (New York, Toronto), enough for stand-up, reviews and questions. Work carries on overnight and is ready in your morning.
USA and Canada (Pacific)
For California or Vancouver we agree a fixed early window, typically 7:00–9:00 am Pacific, plus written hand-offs at the end of your day. We are open that overlap is shorter here.
Australia
India is 4.5 to 5.5 hours behind Sydney and Melbourne, so our normal day overlaps your afternoon, roughly 1:30–5:30 pm AEST. Perth overlaps from about 11:30 am onwards.
Try before you commit
Start with a one-week paid pilot
Before committing to a month, you can start with a one-week paid pilot. The developer works on a real ticket from your backlog, in your repository and tools, with the same daily updates as a normal engagement. At the end you decide whether to continue, change developer or stop. The pilot is billed at the hourly rate for the hours worked, and the code is yours.
Replacement if it is not a fit
If the developer is not the right fit, tell us and we will replace the developer at no extra charge. The new developer is briefed from the shared notes and tickets, and we overlap the hand-over where we can so you do not lose momentum.
Hiring Shopify developers: questions
How much does it cost to hire a Shopify developer from India?
Indicatively, a full-time dedicated Shopify developer from RED SAG costs about $1,700–3,500 a month depending on seniority, and hourly work is about $15–30 an hour. The rates table shows the ranges in GBP, AUD, CAD and INR too. Fixed-price theme or app work is quoted per scope before anything starts.
Can agencies use your Shopify developers white-label?
Yes. We sign your NDA, work through your Shopify Partner account or collaborator access, and communicate only through your tools. We do not contact your clients unless you ask us to, and we keep our name out of theme code and handover notes. See our white-label development page for how agencies usually work with us.
Do your developers work on Shopify Plus stores?
Yes. Plus stores bring extra options such as checkout UI extensions, Functions for more customisation, B2B features and expansion stores. A Shopify Plus developer has to know where those options end, so ours work within whichever plan you have and tell you plainly if a request needs Plus, rather than building a fragile workaround.
Should we go headless with Hydrogen?
Only if a theme genuinely holds you back, for example with complex content, a very custom front end or strict performance needs. Headless adds hosting, development and maintenance cost. For most stores a well-built Online Store 2.0 theme is cheaper to run, and we will tell you if that is the better choice.
How quickly can a Shopify developer start?
Usually within a week, depending on availability and whether your work is mainly theme, app or checkout development. If you have a launch or sale date, share it on the first call so we can plan access, the pilot and any theme freeze around it.
What if the Shopify developer is not a good fit?
Tell us what is not working. We will replace the developer at no extra charge and hand over through the Git history, tickets and store notes, so the new developer does not start from zero. The one-week paid pilot helps you judge fit before a monthly commitment.
Will changes be tested before they reach our live store?
Yes. Theme work is done in a development or duplicate theme with a preview link for you to check on desktop and mobile. App changes are tested on a development store first. Nothing is published to the live theme until you approve it.
Do we need a Shopify theme developer or a Shopify app developer?
It depends on the change. Layout, sections, product pages and speed work are theme jobs in Liquid. Anything that stores its own data, talks to another system or runs inside the Shopify admin is app work with the GraphQL Admin API. Tell us the problem rather than the job title, and we will assign someone strong on the side your backlog needs.
