Shopify developer for stores that require reliable theme customizations, integrations, and complex bug fixes – without disrupting checkout.
I work safely in a duplicate theme, test on mobile and desktop, and provide clear handoff notes. My experience with Ruby on Rails, FastAPI, React, and APIs is useful when a Shopify request requires custom backend logic or automation—not just another app installation.
I can help with:
• Theme customization and custom Liquid sections
• Custom app development and API integrations
• Storefront bugs, search issues, and JavaScript fixes
• Order, shipping, and app integrations
• Custom Shopify functionality backed by 3rd-party APIs
• Reliable ongoing technical support
Send your store URL and the result you want. I'll tell you the safest practical path to implement it.

I specialize in React and React Native apps - mobile, web, and the backend that connects them. From cross-platform mobile apps deployed to both stores, to complex admin panels with analytics dashboards, personalization engines, and real-time data flows.
🤖 𝐇𝐨𝐰 𝐈 𝐮𝐬𝐞 𝐀𝐈 𝐢𝐧 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐬:
I've shipped AI features that solve real business problems, not demos. Recent examples:
• Automated clinical documentation for physicians using ambient listening. Doctors capture encounters hands-free, AI generates SOAP notes instantly. Reduced documentation time by hours per day.
• AI-powered financial analytics for investors. Real-time market insights, anomaly detection, and AI summaries that surface what matters without manual research.
• Integrated AI assistants into SaaS task management. Helping teams manage projects, generate suggestions, and stay on top of workload without switching tools.
I also use AI heavily in my own development workflow. Claude Code, Cursor, and AI-assisted testing help me ship MVPs 30-40% faster without cutting corners on code quality.
💡 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐩𝐫𝐨𝐛𝐥𝐞𝐦𝐬 𝐈'𝐯𝐞 𝐬𝐨𝐥𝐯𝐞𝐝:
• A healthcare company needed to connect remote clinicians to hospital EHR systems securely. I built the mobile app and backend integration using SMART on FHIR, cutting manual data entry out of their workflow entirely.
• An e-commerce platform was losing $30K/month to fraudulent transactions. I designed and implemented a fraud prevention system across their microservice architecture that stopped it.
• A restaurant marketplace needed to compete with large platforms. I built their mobile app, admin portal, and backend from scratch.
• An EdTech company needed a way to share educational video without YouTube's ads and recommendations. I built a multi-tenant SaaS platform with branded video pages, role-based access, and analytics.
• A fitness brand needed their video library accessible offline and castable to TV. I built a React Native app with custom video players, offline downloads, and casting support.

I cover the full product - mobile app, web frontend, and backend - so you don't lose weeks coordinating between developers who don't share context. I've shipped products across iOS, Android, and web. I work in short cycles, keep communication tight, and treat your launch date as a real constraint, not a suggestion.
If you're building a mobile SaaS, an AI-powered product, or need to move fast without sacrificing quality - let's talk.

💫Living the Shopify ecosystem daily. I am not interested in just building or optimizing Shopify stores and Shopify apps - I breathe life into them with my proactive approach, transforming your digital presence into a high-converting masterpiece.
I am a Shopify developer who actually cares if your store sells, not just if it looks nice. Shopify app developer who's been through Shopify's strict review process enough times to write clean code from the start - there will be no bloated JS and no surprises.
What I’ve achieved as a Shopify developer so far:
🟢 developed 58 Shopify websites, including 28 custom Shopify store setup, 20 on them are on Shopify Plus. My clients, who are fashion, supplement, lifestyle, pet supplies and other brands, earned around 50M$ after my Shopify development assistance averaging a 60% conversion rate lift.
🟢 20 stores built where I was converting Figma designs into Shopify pages with pixel perfect accuracy, cutting launch timelines by 30%.
🟢 developed a lot o Shopify apps - as a certified Shopify app developer, built 50 public or custom apps that pass the strictest "Built for Shopify" standards and maintain a solid 4.9★ rating for years.
🟢 mastered the art of Shopify migration. I’ve completed 27 Shopify migrations - from Wordpress WooCommerce, Magento, and WordPress to Shopify. As a Shopify developer, I guarantee an imperceptible move where your SEO authority and customer data remain untouched with less than 40 minutes site downtime.
🟢 as an expert Shopify developer, I use Liquid to build high-performance storefronts, consistently achieving 95+ PageSpeed scores.
As a Shopify developer, I’ve learned that the difference between a storefront and a powerhouse lies in the architecture. Over the last 5 years, I’ve seen how many businesses hit a "glass ceiling" because of poor technical execution. My mission is to ensure that your Shopify store ecosystem is a driver of growth, not a bottleneck.
Core services delivered by me as a Shopify expert:
☑️ Enterprise Shopify Plus Builds: Full-cycle execution for high-scale brands needing custom logic and API integrations (ERP, CRM, SaaS).
☑️ Public & Custom Shopify App Development: From private integrations to apps listed on the Shopify app Store using the latest React Router stacks.
☑️ Bespoke Shopify Theme Development: Converting Figma design into high-converting Shopify theme. A Shopify developer must ensure every pixel serves the conversion - like a proper Shopify designer.
☑️ Shopify developer - Performance and Audit: Deep-dive technical audits and "trouble-shooting." As a Shopify developer, I specialize in liquid development and regularly boost conversion rate metrics by up to 120% through advanced performance tuning and tech debt fixing.
☑️ Shopify developer - Headless Experience: Within Shopify hydrogen theme stack, I am specialized in modern stacks for brands that want to push the boundaries of the Shopify ecosystem.
Why trust your brand to me as a seasoned Shopify developer?
1 Strategic Thinking. I don't just "fix bugs" - I look at your store through the lens of a Shopify developer expert who understands Shopify CRO, Shopify SEO, google ads and user psychology.
2 No Technical Debt. Many Shopify developers build for today; as a Shopify web developer, I build for your future. I use Git-based workflows and scalable processes so your site can grow with you.
3 Always Transparent Communication. You won't hear "dev-speak" from me. I communicate as a business partner and a Shopify expert who focuses on what actually moves the needle for your ROI.
My Tech Stack (Mastered by a Shopify developer seo marketing):
Shopify Plus | Shopify expert | Marketplace specialist | Shopify App Development | Headless Shopify | Shopify SEO | Shopify designer | Liquid developer | React | Shopify Theme Development | Shopify 2.0 | GraphQL | Node.js | Shopify Migration | Shopify Redesign | Figma to Shopify | Shopify expert | Tailwind | Shopify CRO | Wordpress to Shopify migration | Shopify marketing | Migration to Shopify | Shopify custom coding Shopify web development | Shopify cro | Shopify developer cro | Kajabi | HTML to Shopify | Liquid | Shopify web developer
I know you are looking for a partner who takes as much pride in your Shopify store / app stability as you do in its growth. Let’s talk. My goal as a Shopify designer and Shopify developer is to strip away the technical noise so you can focus entirely on your vision. Send me a message with your challenges, and we’ll build the high-performance foundation your brand deserves. Just elite execution.
