Implement Shopify Billing API and fix OAuth issue for Public Shopify App
Karan was able to address our challenges with Shopify quickly, was able to work within a team that he hadn't previously met, and answered all questions that I had in relation to the issue. It was a pleasure to work with him!

Job Success
Nabha, India - 4:33 pm local time
Since 2020, I have logged 5,000+ hours on Upwork. I take ownership from architecture and implementation through launch, review, and maintenance. I can build a new system end to end, join an existing codebase, or resolve a release blocker.
SELECTED RESULTS
• My work includes 7 apps published on the Shopify App Store, including 3 public apps I own and operate
• Shopify Scripts-to-Functions migration completed in 4 days
• One rejected App Store submission approved within 48 hours after I resolved its privacy and UI/UX blockers
• Mobile PageSpeed improved from 35 to 90+ and LCP was reduced below 2 seconds; across several measured projects, clients also recorded 20–30% conversion gains alongside the performance improvements
SHOPIFY APPS, FUNCTIONS, AND SHOPIFY PLUS
• Public and custom Shopify apps: React Router, App Bridge, embedded admin and B2B workflows, OAuth, Billing API, subscriptions, GraphQL Admin API, webhooks, theme app extensions, app proxies, data migration, and maintenance
• Rust and WebAssembly Shopify Functions: unified Discount Function API, cart and checkout validation, custom discount logic, and shipping discounts
• Shopify Plus and Checkout Extensibility: legacy Shopify Scripts migrations, checkout logic, protected customer data approval, and API integrations
• Shopify App Store submission, compliance, rejected-app rescue, and post-launch development
STOREFRONTS, PERFORMANCE, AND CRO
I build custom Liquid themes and headless Shopify storefronts using Hydrogen or Next.js with the Storefront API. I also migrated my own store from a Shopify Liquid theme to a custom Next.js platform.
My performance work covers Core Web Vitals, mobile PageSpeed, LCP, CLS, INP, JavaScript and Liquid bottlenecks, app and theme audits, responsive UX, and conversion rate optimization. I implement the improvements—not just deliver an audit.
AI AND COMMERCE AUTOMATION
I build production AI systems connected to Shopify data and business actions, not standalone demonstrations.
• Production AI support agent with 25 action tools for refunds, replacements, address changes, discounts, cart updates, and ticket creation across 5 LLM providers
• WooCommerce-to-Shopify importer using Shopify Bulk Operations, AI enrichment, human review, and reliable background processing
• Returns and exchanges automation with approval workflows, EasyPost return labels, and proportional multi-gateway refunds
• Open-source Shopify Model Context Protocol server for the Shopify Admin API
SHOPIFY OPERATOR EXPERIENCE
I own and operate Stars In Hands, a 9-language personalized-product platform with 7 live product editors and configurators, 300-DPI print rendering, 4 print-on-demand fulfillment providers, a published ChatGPT App, and a Model Context Protocol server.
Running my own commerce products gives me firsthand experience with merchandising, conversion, customer support, fulfillment, app maintenance, and the operational consequences of technical decisions.
CORE STACK
Shopify Functions, Rust, WebAssembly, Liquid, GraphQL Admin API, Storefront API, React Router, React, Next.js, TypeScript, Node.js, Python, Django, Prisma, PostgreSQL, and AWS.
WORKING WITH ME
I provide 6–7 hours of overlap with U.S. Pacific Time, usually respond within 4 hours, and work on hourly contracts.
Send your store or app URL, the current issue, and the result you need. I’ll review the scope and reply with the likely implementation path, key risks, and next step.
