Shopify / Full-stack / Automation

Shopify development for stores that are already feeling the limits.

Themes, apps, integrations, migrations, and automation built with full awareness of how ecommerce systems break in production.

Capabilities

Where Shopify work usually breaks

Shopify themes that behave

Clean Liquid architecture, custom sections, product templates, and storefront logic that do not collapse under edge cases.

Apps and integrations with clear boundaries

Private apps, app architecture, admin workflows, OAuth, GraphQL, webhooks, sync systems, and merchant-facing interfaces.

Data, scraping, and migration

Product imports, multilingual data mapping, redirects, collection structures, external database migration, and ecommerce data cleanup.

Automation attached to operations

AI tools, product enrichment, classification, content workflows, and repetitive admin-task automation built around real business movement.

Technical rescue

Broken themes, failing API integrations, tangled metafields, half-finished apps, and undocumented changes reconstructed into a system that can be worked on again.

Clear communication without hand-holding

Scoping, tradeoffs, handoff notes, and technical decisions explained clearly without turning the client into a developer.

Shopify work is rarely only a theme problem.

It is usually a data problem, integration problem, workflow problem, performance problem, content-model problem, or production ownership problem.

Mirakle treats Shopify as an ecommerce system: storefront, admin workflows, APIs, apps, product data, automations, and the human process around it.

Technical shape

The work behind the storefront

Shopify frontend

Liquid, custom sections, product templates, collection pages, metaobject-driven content, and theme architecture.

Shopify backend

Admin API, Storefront API, GraphQL, webhooks, OAuth, app architecture, and sync logic.

Full-stack systems

Rails, Node, React, PostgreSQL, MongoDB, TypeScript, and the glue code ecommerce teams actually rely on.

Automation and AI

Python scripts, scraping, ETL, product enrichment, prompt systems, RAG prototypes, and AI-assisted ecommerce tooling.

Typical problems

Good reasons to bring this in

The theme is hacked together

Sections work until a campaign, variant, market, or content change exposes the shortcuts.

Apps do not agree with each other

Data, webhooks, metafields, and external systems need boundaries and sync logic.

Migration risk is blocking progress

Products, redirects, collections, content, and data structures need a controlled move.

AI ideas need production discipline

The useful version is tied to product operations, content workflows, or admin tasks - not a demo.

Fit

Good-fit Shopify work

  • A custom storefront or section your current theme cannot handle cleanly.
  • Product, collection, redirect, or content migration into Shopify.
  • A Shopify app, internal tool, integration, or automation around the store.
  • API, data model, metafield, metaobject, or production debugging work.
  • AI features attached to real ecommerce operations.

Send the broken version. That is the useful one.

Broken theme, unclear migration, half-built app, strange API problem, AI idea, or a storefront workflow nobody wants to touch anymore.
