I build Shopify storefronts, custom apps, and business systems that are ready to run.

}_I can own a complete build, join an existing codebase, rescue a difficult feature, or provide ongoing development and production support.
Complete storefront themes built from scratch, or focused improvements to an existing theme without losing merchant content and settings.
Best fit: New stores, redesigns, theme rebuilds, and conversion-focused fixes
Private and custom apps that connect Shopify with the workflows, data, and services a business actually needs.
Best fit: Manual workflows, store-specific features, integrations, and automation
Custom storefronts and multi-brand platforms when a standard theme cannot support the required customer experience or business model.
Best fit: Complex catalogs, custom buying journeys, and connected commerce platforms
Full-stack systems for sales, operations, and production, delivered with the infrastructure and documentation needed to keep them healthy.
Best fit: Internal tools, legacy modernization, integrations, and production support
Featured projects lead with Shopify theme and app work. Private client systems are clearly labelled where source code and live access cannot be shared.
I built a complete Shopify Online Store theme for a fashion storefront using Liquid, reusable sections, merchant-controlled theme settings, and responsive product, collection, search, cart, and editorial templates. The work includes native product-option swatches, accessible interaction states, structured SEO, performance tuning, and a controlled unpublished-theme workflow for review before release.
I built a production Shopify app for GST-compliant invoices and credit notes. The embedded React Router app authenticates with Shopify, stores sessions and document records in an isolated Azure SQL schema through Prisma, renders deterministic PDFs, validates supplier and customer tax details, and ships through a documented AWS Lightsail release and rollback process.
I developed a Shopify theme and custom Cloudflare Worker app for a school-uniform business. Schools submit kit designs or registrations, staff convert requests into school-specific products and collections, parents order with student and name-printing details, and the embedded admin app supports pricing, reports, packing, delivery, and store configuration.
I developed a private Shopify product-personalization app for custom merchandise. It combines an embedded template editor, a storefront customizer, a theme app extension, Shopify Functions for pricing and cart validation, secure design storage, order webhooks, and print-ready rendering for multiple decoration methods.
I built a multi-tenant e-commerce platform for Indian apparel brands: a Next.js 16 App Router storefront with an 84-page admin console, and an Express 5 REST API over Azure SQL. The API is EXECUTE-only, so every data access runs through one of 391 stored procedures, and the GST pricing engine exists twice - a JavaScript reference implementation and a byte-identical SQL port kept in step by a fuzzing differential test. Each brand resolves from its own domain and carries its own theme, settings and Razorpay account. I also wrote a browser garment designer that composites SVG print panels and removes artwork backgrounds in a Web Worker using a self-hosted ONNX model.
Yoode 365 is an internal CRM I built to move a garment-decoration company's Windows desktop system into the browser for sales reps, the production floor, and management. It runs on Laravel against an existing Azure SQL Server schema, so I wrote the whole data layer with the query builder and the legacy stored procedures instead of Eloquent, letting SQL Server own all tax and pricing maths. I implemented WebAuthn passkeys and TOTP as second factors with device approval, rolling expiry and per-user device caps, quotation delivery over the Interakt WhatsApp API, HTMX partial refreshes, a Vue product picker, and Monolog critical-log alerts. It deploys to AWS Elastic Beanstalk behind nginx with CloudWatch log streaming.
I help e-commerce brands and operations teams turn complex requirements into dependable software. My work covers Shopify themes built from scratch, custom Shopify apps and extensions, headless storefronts, internal CRM and ERP workflows, API integrations, and AWS delivery. Since 2018, I have taken projects from discovery and architecture through implementation, testing, release, production troubleshooting, and documented handoff. I use AI-assisted development where it improves speed and coverage, while keeping decisions, code quality, and verification human-led.
