05 / SKILLS & EXPERTISE

Every capability.
Clearly explained.

A complete, text-first overview of the Shopify, application, full stack, performance, SEO, and delivery skills I use for ecommerce projects.

01

Shopify storefront development

Building flexible, maintainable storefronts that merchants can operate confidently and customers can use easily.

Shopify Liquid

I use Liquid to build clean templates, reusable theme components, product experiences, collection pages, cart behavior, and merchant-controlled content.

Shopify Online Store 2.0

I create JSON templates, app blocks, dynamic sections, metafield-driven content, and flexible theme architecture for modern Shopify stores.

Custom Shopify themes

I translate brand and UX requirements into responsive, accessible, conversion-focused themes without unnecessary code or heavy page builders.

Shopify theme customization

I extend existing themes safely, improve section flexibility, repair technical problems, and preserve maintainability for future updates.

02

Shopify app engineering

Extending Shopify with secure applications and integrations built around real operational needs.

Custom Shopify apps

I build embedded, public, and custom-distribution apps for automation, merchant workflows, subscriptions, reporting, and unique commerce features.

Shopify Admin API

I work with products, orders, customers, inventory, fulfillment, discounts, metaobjects, and other Shopify resources through GraphQL APIs.

Shopify Storefront API

I build custom shopping experiences that retrieve catalog data, manage carts, and support headless or highly tailored storefront journeys.

App Bridge and Polaris

I create Shopify-native admin experiences with App Bridge patterns and Polaris components so applications feel familiar to merchants.

Webhooks and background workflows

I design reliable event-driven systems for order events, app lifecycle events, inventory changes, customer updates, and data synchronization.

Billing and subscriptions

I implement Shopify app billing flows, recurring plans, usage-aware product logic, and secure entitlement handling.

03

Full stack development

Connecting polished interfaces to dependable server-side systems, databases, APIs, and deployment infrastructure.

React and TypeScript

I build component-based interfaces with clear types, predictable data flow, accessibility, and performance-conscious client behavior.

Node.js and server development

I create backend routes, authentication flows, business logic, scheduled work, integrations, validation, and secure data operations.

GraphQL and REST APIs

I design and consume APIs, handle pagination and rate limits, validate payloads, manage errors, and keep integrations observable.

Postgres and data modeling

I design relational schemas, migrations, indexes, reporting queries, audit trails, and serverless database access for scalable applications.

Git, GitHub, and CI/CD

I use version control, focused reviews, deployment previews, repeatable builds, and production workflows that reduce release risk.

Vercel deployment

I deploy Next.js applications with environment management, preview deployments, caching, analytics, performance monitoring, and production domains.

04

Shopify Plus and multi-market commerce

Helping growing brands operate across markets, channels, teams, and complex commerce requirements.

Shopify Plus development

I support advanced storefronts, checkout extensibility, automation, integrations, expansion architecture, and enterprise delivery workflows.

Shopify Markets

I plan domains, currencies, languages, catalogs, regional merchandising, localization, and market-aware customer experiences.

Hydrogen and headless Shopify

I build React-based storefronts with Hydrogen, Remix, and the Storefront API when brands need greater frontend control and flexibility.

Third-party integrations

I connect ERPs, CRMs, fulfillment systems, subscriptions, reviews, search, analytics, marketing tools, and custom business platforms.

05

Performance, SEO, and conversion

Improving technical quality and customer journeys so storefronts can be discovered, trusted, and used efficiently.

Core Web Vitals

I optimize loading, responsiveness, and visual stability through lean JavaScript, efficient Liquid, asset strategy, rendering decisions, and measurement.

Technical SEO

I improve metadata, canonicals, structured data, crawlability, sitemaps, internal linking, semantic HTML, redirects, and ecommerce search signals.

Conversion rate optimization

I evaluate navigation, product discovery, product pages, carts, trust, calls to action, and friction using evidence rather than decoration.

Accessibility

I build keyboard-friendly, semantic, readable interfaces with useful labels, focus states, contrast, and screen-reader-aware behavior.

Analytics and measurement

I configure privacy-conscious analytics, event tracking, search performance data, and reporting that connects engineering work to outcomes.

06

Professional delivery

Technical work supported by the communication and structure modern teams need.

Technical discovery

I turn business requirements into practical architecture, scope, priorities, risks, and measurable acceptance criteria.

Code audits

I review Shopify themes, apps, integrations, performance, SEO, accessibility, and maintainability before recommending focused improvements.

Documentation and handover

I document setup, decisions, merchant workflows, deployment, and maintenance so teams are not dependent on hidden knowledge.

Remote collaboration

I work asynchronously with planned time-zone overlap, clear progress reporting, written decisions, and dependable delivery across remote teams.
