My core backend stack includes PHP, JavaScript, MySQL, Node.js, Shopify Liquid, Admin API, Storefront API, GraphQL, REST API, Webhooks, WordPress/WooCommerce hooks, custom plugins, cron jobs, product and order metadata, inventory workflows, subscription logic, shipping rules, database work, and backend debugging. I also handle server migration, hosting migration, DNS, A/CNAME/MX/TXT records, nameservers, SSL/TLS, Cloudflare, CDN, caching, backups, database migration, and staging-to-production deployment. For modern applications, I work with TypeScript, Next.js, React, JavaScript, GSAP, and ScrollTrigger for Shopify apps, headless commerce, custom storefronts, interactive product experiences, and performance-focused web applications. I also work with LMS, xAPI, learner tracking, and AI-assisted development using Cursor for coding, debugging, refactoring, prototyping, and API implementation. On Upwork, I have completed Shopify work involving rental workflows, domestic and international shipping, custom store functionality, and third-party integrations, as well as a Next.js + GSAP project.
