From idea to launch, fast

A fast launch only counts if the store still converts after the first sale. Each sprint is fixed in scope and built on an unpublished theme, with custom code kept in theme sections or an app, so a theme update or app install doesn't wipe it out.

1 week

MVP in 1 week

For founders and brands who need a working Shopify store taking real orders now.

  • One core buying flow built end to end: collection, product page, cart and checkout
  • An Online Store 2.0 theme with sections and blocks your team can edit
  • Payments, shipping zones, taxes and order emails set up and tested with real orders
  • Analytics and pixels connected, live on your own domain

Scoped to one core flow. Final timeline confirmed after a 30-minute call.

2 weeks

Idea to market in 2 weeks

For brands launching a full catalogue or moving a store to Shopify.

  • Week 1: theme build, product and collection import, navigation and key templates
  • Week 2: discounts and checkout rules with Shopify Functions, apps and Markets
  • SEO basics: titles, structured data, redirects and a Core Web Vitals pass
  • Launch checklist, test orders and a handoff doc for your merchandisers

Fits a v1 with 2 to 3 core flows. Payment approvals, catalogue cleanup and late content can add time.

Rescue

Rescue sprint for an existing Shopify store

For stores that are slow, broken after an app or theme update, or lost custom logic in 2026.

  • App and theme audit with a written priority list
  • Rebuild Shopify Scripts logic as Shopify Functions (Scripts stopped running on June 30, 2026)
  • Replace script tags with theme app extensions and web pixels before storefront script tags stop on March 1, 2027
  • Speed fixes: unused apps, heavy Liquid, images and third-party scripts

A focused sprint on the top issues. Bigger rebuilds are split into follow-up milestones.

Shopify that's built for the business, not just the theme demo

Shopify is the right call when commerce is the product: you want hosted checkout, reliable payments and a team that runs the store from Shopify admin. I build custom theme sections and blocks, product and collection templates, metafields and metaobjects, Shopify Functions for discounts, shipping and payment rules, checkout and customer account extensions, and integrations with your ERP, CRM or 3PL. When it's really needed, I build a headless storefront with Hydrogen. As a Shopify expert who is also a full-stack engineer, I keep custom code in theme sections or a custom app under version control, and when you hire Shopify developer help from me, you work directly with the person writing it.

Shopify itself changed a lot in 2026. Shopify Scripts stopped running on June 30, 2026, so custom discount, shipping and payment logic now has to live in Shopify Functions. Script tags stopped running on the Order status page for non-Plus stores on August 26, 2026, and storefront script tags stop on March 1, 2027. On the AI side, the Winter '26 Edition turned Sidekick into an assistant that can edit themes, build Flow automations and generate custom admin apps, and Agentic Storefronts put products into ChatGPT, Microsoft Copilot and Perplexity. The Spring '26 Edition (June 17, 2026) added 150+ updates around agentic commerce, including Shopify Catalog and checkout inside Copilot. I help stores use this properly with clean product data and practical AI features, and I pair Shopify with Laravel when you need a custom portal or back office.

Why brands hire me as their Shopify developer

I'm a freelance Shopify developer in Pakistan, based in Lahore and working with brands worldwide: 12+ years of delivery, 150+ clients, 500+ projects and 95% repeat or referral. Because I build full-stack products too, I know when a Shopify app is the right answer, when a small Function or theme section beats another monthly subscription, and when WooCommerce on WordPress fits your store better. You get written notes on everything I customise, so you are never locked in. Most brands hire a Shopify developer for one of three reasons: a new store or migration, a store that is slow or broken, or custom logic that stopped working after Shopify's 2026 changes.

Have a Shopify store to build or fix? Let's ship it.

Send me your idea or your store URL and tell me where it stands. I'll come back with a plan, a realistic timeline and a custom quote.

1.Research
I start with your catalogue, markets and currencies, must-have apps, current theme and any custom logic (Scripts, script tags, checkout tweaks), plus who edits the store every day. Output: a short written brief with assumptions, risks and a proposed theme, app and Functions plan you can challenge.
2.Concept Design
Before building, we lock the templates (home, collection, product, cart), sections and blocks, metafields, the app shortlist and a definition of done for the first milestone. Every app has to earn its place, because each one adds cost and page weight.
3.Implementation
I build on an unpublished theme and a development store in slices you can click through: sections, templates, Functions, checkout extensions and integrations. Code lives in Git, and API tokens and secrets stay out of the theme.
4.Testing
Nothing ships untested: test orders on desktop and mobile, discount codes, payment success and failure, shipping rates, app conflicts and a Core Web Vitals pass. We publish with the old theme kept as a rollback, and your team gets a short handoff.

Vibe-coded Shopify app or theme? I'll make it production-ready

AI tools like Cursor, Claude, ChatGPT, Lovable and Bolt can write a Shopify app, a theme section or a headless storefront in an afternoon, and Sidekick can now generate custom admin apps from a prompt. That speed is useful, but AI-generated code often skips the checks that keep a store, its customer data and its checkout safe. I review and fix vibe-coded Shopify code so it is safe to launch and easy for the next developer to maintain.

Vibe code cleanup

Your app or theme works, but nobody wants to touch the code. I refactor it without breaking what already sells.

  • Structure: sections, blocks and snippets where Shopify themes expect them
  • Custom logic moved into Shopify Functions or a proper app instead of theme hacks
  • Theme Check and linting on every change
  • Metafields and metaobjects instead of hard-coded content
  • Deploy: Git, Shopify CLI, a development store and a repeatable release

Vibe coding security audit

AI-generated Shopify code often leaks access or trusts requests it shouldn't. A security audit finds the gaps before someone else does.

  • Exposed secrets: Admin API tokens or app secrets in theme JavaScript or the repo
  • Unverified webhooks and app proxy requests (missing HMAC checks)
  • Over-broad API scopes and missing session checks on app routes
  • Unescaped Liquid output (XSS) from metafields and customer input
  • Customer data handling and missing privacy webhooks

How I fix AI-generated Shopify code

1

Audit report

I review the theme, apps, API access and integrations, then send a written report ranked by severity: what is risky now and what can wait.

2

Fix critical issues

Security holes go first: tokens rotated, webhooks verified, scopes reduced and output escaped. The store keeps selling while I work.

3

Hardening and handoff

Cleanup, a safe release process with a development store, monitoring, then a handoff doc so your team can keep building safely.

Shopify developer FAQ

What Shopify work do you take on?

New stores and redesigns, custom theme sections and blocks, product and collection templates, metafields and metaobjects, Shopify Functions, checkout and customer account extensions, custom and private apps, ERP, CRM and 3PL integrations, migrations, speed work and ongoing support. I handle the whole build, from catalogue structure to launch.

Can you migrate my store from WooCommerce or another platform to Shopify?

Yes. I move products, variants, collections, customers and order history where the platform allows it, set up 301 redirects so you keep your SEO, and rebuild custom features as theme sections, Shopify Functions or apps. We test the new store with real orders before switching the domain.

My Shopify Scripts stopped working. Can you rebuild them with Shopify Functions?

Yes. Shopify Scripts stopped running on June 30, 2026. I go through your Scripts customizations report, decide which rules are still needed, and rebuild them as Shopify Functions for discounts, shipping and payment customisations, or replace them with a reliable app where one already does the job.

Do you build custom Shopify apps and checkout extensions?

Yes, when a real workflow can't be covered by settings or a good off-the-shelf app. I build custom apps with the Shopify CLI, checkout and Thank you page extensions, customer account extensions, theme app extensions and web pixels, and I replace old script tags before storefront script tags stop on March 1, 2027.

Can you make my store ready for AI shopping and Sidekick?

Yes. Shopify's Agentic Storefronts can show your products inside ChatGPT, Microsoft Copilot and Perplexity, and that only works well with clean product data: clear titles, complete variants, metafields and good descriptions. I tidy up the catalogue, set up the channels, and build AI features like smart search or support assistants where they help.

Shopify or WooCommerce: which should I choose?

Shopify when you want hosted commerce, a secure checkout and less maintenance. WooCommerce when content, SEO and deep custom features matter and you want to own the whole stack. I build both, so I recommend based on your catalogue and team, not habit. See WordPress development for the WooCommerce side.

Can you clean up or secure a vibe-coded Shopify app or theme?

Yes. If your app, theme or headless storefront was built fast with Cursor, Claude, ChatGPT, Lovable, Bolt or Sidekick, I start with a code and security audit: exposed API tokens, unverified webhooks, over-broad scopes, unescaped Liquid output and unsafe handling of customer data. You get a written report ranked by severity, then I fix the critical issues first. Details are on the vibe code security audit page.

Can you really launch a Shopify MVP in 1 week?

Yes, when the MVP is scoped to one core buying flow: a focused catalogue, product pages, cart and checkout, live on your domain. Extra features move into the next milestone instead of stretching the week. A full catalogue or a migration fits the 2-week idea-to-market sprint. We agree what fits on a 30-minute call, and I confirm the timeline then, not before.

How do we get started?

Send me a short brief through the contact form: your store URL if you have one, your theme and must-have apps, what you want to build or fix, and your timeline. I work remotely from Lahore, Pakistan with clients worldwide, and I reply with questions or a proposed plan and a custom quote. For ongoing updates after launch, see support and maintenance.
