If your Shopify store is slow, broken, losing conversions, needs a custom app built, or needs to connect to an external system — I have solved it before and I can solve it for you. I work 100% inside Shopify. Not a generalist who added Shopify to a skills list — a dedicated Shopify developer with 6 years of focused experience across app development, theme development, speed optimization, integrations, and CRO. I work best with DTC brands, SaaS founders building on Shopify, and agencies that need a reliable specialist for complex projects. CUSTOM SHOPIFY APP DEVELOPMENT I have built and shipped 4 apps through Shopify's full review process — OAuth, billing systems, GDPR webhooks, App Store compliance, and deployment. Most Shopify developers on Upwork have never done this. My published apps: Stock Alert — real-time inventory monitoring, auto-hide sold-out products, auto-republish when restocked, email and Slack alerts, GDPR compliant Shoppable Posts — turns blog posts into shoppable product displays with variant selection and add-to-cart DemandMind Forecasting — Shopify app layer over a client's AI forecasting engine, Python backend, multi-store support BGN to EUR Converter — live currency conversion display for Shopify stores Full stack: React, Node.js, TypeScript, Polaris, App Bridge, GraphQL, webhooks, PostgreSQL. Results clients have seen: Mobile Lighthouse score from 38 to 92 (Kind Laundry — full speed overhaul) OMS API response time cut from 4 seconds to 400ms Full print-on-demand fulfillment platform built from scratch Clean, accurate, matched the design perfectly. He handled technical details without needing constant direction. SHOPIFY THEME DEVELOPMENT Custom Shopify themes built from scratch — Liquid, Shopify 2.0, clean and maintainable code. No page builders, no shortcuts. Figma to Shopify — pixel-perfect conversion from any design file Custom sections, blocks, and templates Homepage, PDP, PLP, landing pages, full store builds Theme customization on Dawn, Prestige, Impulse, Refine and more Shopify Plus theme customization including custom checkout Mobile-first responsive design SPEED OPTIMIZATION AND CORE WEB VITALS A slow Shopify store is losing you money every day. I fix it with real numbers, not vague promises. Lighthouse score improvements with before and after results Core Web Vitals: LCP, CLS, FID fixes JavaScript optimization and cleanup App bloat removal and conflict resolution Liquid performance fixes and image optimization SHOPIFY PLUS DEVELOPMENT Custom checkout extensions and Checkout Extensibility Shopify Functions — discount logic, shipping rules, payment customization Shopify Flow automations B2B and wholesale store setup Multi-currency and international stores API INTEGRATIONS AND CUSTOM SOLUTIONS ERP, CRM, and OMS integrations Third-party payment and shipping systems Webhook architecture and real-time data sync Custom admin tools and automation dashboards GraphQL and REST API development LANDING PAGE DEVELOPMENT AND CRO High-converting landing page development UX audits — finding where customers drop off and why Product page and checkout flow optimization AOV improvements — bundles, upsells, cross-sells Trust signals, social proof, and review integration MIGRATIONS WooCommerce, Magento, Wix, BigCommerce to Shopify Products, customers, orders, metafields — all migrated SEO-safe URL structure and redirect mapping, zero data loss BUG FIXES AND TROUBLESHOOTING Theme bugs, broken layouts, JavaScript errors, app conflicts Liquid syntax and rendering issues Mobile display problems and post-update breakages Broken API integrations and performance regressions STORE SETUP AND ADMINISTRATION Full store setup — products, collections, navigation, shipping, taxes, payments App installation and configuration: Klaviyo, Yotpo, Judge.me, Recharge, Bold, PageFly Ongoing maintenance, analytics setup, GA4 and Meta Pixel tracking I give honest assessments. If something is not worth building or there is a simpler solution, I will tell you. I do not pad hours and I do not disappear mid-project. Code is production-ready before handover. Send me a message with what you are building, what is broken, or what system you need connected. I will give you an honest assessment and a clear path forward within 24 hours.
