What I do

Shopify development services, end to end

Pick a single task or the whole transformation. From Shopify theme and app development to integrations, Shopify Plus and SEO, the areas below cover most Shopify work — and they often overlap on a real project.

Custom development

Shopify app development and custom features built around how your store actually works.

  • Custom Shopify app & plugin development (public & private)
  • Theme sections, blocks and app extensions
  • Checkout & cart customizations (Functions, UI extensions)
  • Performance, SEO-friendly markup and Core Web Vitals

Theme development & customization

I handle theme customization and tweaks solo; full custom theme development from scratch is delivered together with a trusted design & dev team.

  • Theme customization, tweaks & design adjustments (solo)
  • Custom Liquid templating and reusable sections
  • Responsive and accessibility fixes, Online Store 2.0 migrations
  • Ground-up custom Shopify theme development — as part of a team

Integrations

Connect Shopify to the tools that run your business so data flows without manual work.

  • ERP, CRM and accounting (e.g. QuickBooks) integration
  • Marketplaces & channels: eBay, Square, WhatsApp, Google
  • Payment, shipping, tax and inventory sync
  • Custom APIs, webhooks and Google Analytics setup

  • Shopify Plus setup and scripting
  • Headless / composable commerce (Hydrogen)
  • Replatforming and data migration
  • B2B, multi-store and multi-market

Shopify SEO

Shopify SEO optimization that helps your store rank — technical fixes, on-page structure and the tooling to track it.

  • Technical SEO audit & Core Web Vitals / speed
  • On-page SEO: metadata, structured data, internal links
  • Google Search Console & Google Analytics setup
  • SEO apps, redirects and migration-safe SEO

FAQ

Frequently asked questions

Still unsure about something? Ask me directly.

What Shopify development services do you offer?
The full stack: Shopify theme development and customization, custom app and plugin development, third-party integrations, Shopify Plus and headless builds, and Shopify SEO. You can hire me for a single task or an end-to-end project.
How much does Shopify development cost?
It depends on scope. After a short discovery call I give you a fixed, written estimate before any work starts — no open-ended hourly surprises. Small theme tweaks are billed by the task; larger apps and Plus projects are quoted per milestone.
Can you customize an existing theme or build one from scratch?
I customize and extend your current theme solo — clean, maintainable Liquid, design tweaks, new sections and performance fixes. For a full custom theme built from scratch I bring in a trusted design & dev team and lead the project, so you still have a single point of contact.
Do you work with Shopify Plus and headless / Hydrogen?
Yes. I handle Shopify Plus development — scripts, Functions, B2B, multi-store and multi-market — as well as headless / composable commerce with Hydrogen for high-volume stores.
Can you integrate Shopify with my other tools?
Yes. Common integrations include accounting (e.g. QuickBooks), marketplaces and channels (eBay, Square, WhatsApp, Google), ERPs, CRMs, payment and shipping providers, plus custom APIs, webhooks and Google Analytics setup.
Do you offer Shopify SEO?
Yes — focused on what a developer controls: technical SEO audits, site speed and Core Web Vitals, on-page structure and metadata, structured data, Google Search Console and Analytics setup, and migration-safe redirects.
How long does a Shopify project take?
Theme customizations are often a few days to a couple of weeks. Custom apps and integrations typically run two to six weeks. Plus and headless builds are scoped individually. You'll get a timeline with the estimate.
Are you a freelancer or an agency?
I'm an independent, expert Shopify developer. You work directly with the person writing the code — faster decisions, no account managers, and no hand-offs between teams.
