ABOUT ME

Beyond the Frontend.

Hi, I’m Batuhan Kadoğlu, a Shopify and Frontend Developer based in Istanbul. I bring nearly five years of full time remote experience at a U.S. based company, building and maintaining DTC and B2B storefronts. As a dual U.S. and Turkish citizen, I am authorized to work in both countries.

I specialize in Online Store 2.0 theme architecture and ecommerce UX using Liquid, JavaScript, and Shopify APIs. My work includes architecting customer dashboards, implementing subscription based access controls, and developing reusable theme components that merchandising teams can configure. I extend established storefronts while preserving Theme Editor compatibility and existing business logic.

My broader frontend work includes responsive, accessible interfaces built with React, Next.js App Router, and TypeScript, emphasizing reusable component architecture, API integrations, and automated testing with Vitest and Playwright. Across my projects, I prioritize long term maintainability, performance, and technical SEO.

Two brands. Shared foundations.

Lynda Kids: Subscription, Membership and Connected Device Platform (lyndakids.com)

Designed a five tier subscription entitlement system mapping Shopify customer tags to profile, usage, and history limits; led the transition to pooled family allowances while preserving backward compatible limit resolution.
Architected a customer dashboard within the Shopify Liquid theme using JavaScript ES modules, client side routing, and a shared state store, delivering app like account navigation without a separate frontend build pipeline.
Implemented authentication and customer profile synchronization between the storefront and backend, including request signing with HMAC using SHA256, JWT refresh and revocation, and profile updates that account for time zones.
Delivered automated cart discounts through a Vercel serverless service using Shopify Admin GraphQL, with rate limiting, token caching, discount code collision retries, and offer expiration and cooldown controls.
Built customer interfaces for connected device status, conversation history, on demand audio playback, and usage tracking, with scoped dashboard styles isolated from the storefront.

Developed and maintained an Online Store 2.0 furniture storefront, extending a commercial theme across product and collection templates while preserving existing extension points and Theme Editor schema compatibility.

Developed coordinated product discovery across search and collections, combining live suggestions, shared faceted filtering, contextual navigation, mobile filter controls, and persistent grid preferences.
Standardized registration, quote requests, trade applications, and project submissions through reusable form components with validation, file uploads, serverless submission, and reCAPTCHA protection.

Across Both Storefronts

Consolidated duplicated Liquid into reusable snippets and standardized Theme Editor schemas so merchandising teams could configure storefront sections, with consistent linting and formatting across both codebases.
Optimized storefront resource loading through prioritized hero media, deferred noncritical third party scripts, and image loading based on viewport visibility.
Built reusable structured data generators for products, collections, articles, FAQs, and breadcrumbs to support technical SEO across both storefronts.
