Featured Projects & Tools

Proven Shopify Plus client stores and custom developer software I architected solo with React & Next.js.

Shopify Developer & Merchant Toolkit (Enterprise SaaS)
Solo Enterprise SaaS Built by Me
Comprehensive real-time technical audit & CRO roadmap generated in under 60 seconds with zero server bloat.

Shopify Developer & Merchant Toolkit (Enterprise SaaS)

Role: 100% Solo Creator & Full-Stack Architect
The Problem: Merchants and agency developers lack an all-in-one technical platform to audit live storefront performance, evaluate app bloat, and automate technical developer tasks without expensive subscriptions.
What I Engineered: I engineered this enterprise-grade technical performance audit, CRO analyzer, and developer automation suite built from the ground up for modern Shopify merchants and agency developers.
Core Capabilities I Developed:
Autonomous Store Audit Engine: Crawls public Shopify storefronts delivering deep PageSpeed insights, Core Web Vitals (LCP, CLS, INP, TTFB), and an 8-pillar deterministic CRO heuristic evaluation.
AI-Driven Action Plans: Integrates OpenAI gpt-4o-mini (with strict Zod schema validation) and deterministic fallback engine to produce prioritized sprint roadmaps (Quick Wins, High Impact).
Single-Crawl Orchestration: Unified Scan Orchestrator with in-memory TTL caching and SSRF protection to prevent redundant crawls and ensure zero server overload.
12+ Specialized Modules: Shopify App Detector, App Cost Analyzer, SEO Manager, Speed Optimization Planner, Image Optimizer, Theme Intelligence, and 9 standalone developer utilities.

Product Scrapper Bay
Solo Tool Built by Me
Automated migration of 500+ SKUs in minutes, eliminating weeks of manual data entry errors.

Product Scrapper Bay

Role: 100% Solo Creator & Engineer
The Problem: Merchants migrating products to Shopify waste weeks manually copy-pasting product titles, variant options, high-res images, and pricing history from existing catalogs.
What I Engineered: I architected and developed Product Scrapper Bay as an automated e-commerce extraction and catalog migration pipeline. It crawls product URLs, extracts complete product schemas, and exports clean, Shopify-ready CSVs and structured JSON in seconds.
Core Capabilities I Developed:
Automated Variant & Image Extraction: Captures complex color/size variants and full-res gallery assets.
Shopify-Ready CSV Export: Formats extracted catalogs directly into Shopify's native bulk import schema.
Real-time Crawl Engine: Handles dynamic JavaScript rendering and pagination automatically.
Clean React Dashboard: Gives merchants instant preview and schema validation of extracted data.

Shopify Audit AI

Role: Creator & Full-Stack Developer
The Problem: Store owners struggle to diagnose why their checkout rates are dropping or where customer friction points exist on mobile.
What I Engineered: I created this free AI auditing tool that scans Shopify storefronts for speed, Core Web Vitals, and mobile UX bottlenecks, generating actionable conversion-rate optimization (CRO) reports.
Core Capabilities I Developed:
Real-time Core Web Vitals profiling (LCP, CLS, FID) via Google Lighthouse API.
AI-generated CRO suggestions tailored to mobile shoppers.

High-converting Liquid themes, sub-second speed optimization & React/Next.js engineering.

I'm Muhammad Ehtesham Ayyaz, a Shopify developer and front-end engineer based in Pakistan, working remotely with brands and digital agencies worldwide.

For 5+ years I've specialized in custom Shopify 2.0 themes, Liquid templating, and Core Web Vitals speed optimization for stores like Tiletopia, Exercere, Anya Active, and Hanne Bloch. My focus is the technical core of the store that drives revenue: mobile page speed, checkout friction reduction, and conversion rate optimization (CRO).

Alongside Shopify, I have deep front-end engineering expertise in React 19 & Next.js 16. I use this to architect custom merchant tools, interactive dashboards, and developer automation suites like Shopify Developer & Merchant Toolkit and Product Scrapper Bay.

I work exceptionally well with agencies as a white-label developer: disciplined communication, clean Git PRs, documented code, and zero surprises on deadlines.
