Faster stores, fewer manual hours
Ecommerce Engineering
Engineering for the commerce side of your business — from store speed and checkout conversion, through Shopify automation and API integrations, to custom storefronts, payment flows, and the back-office that runs them.
Designed, built, and operated end to end by Fawad Hussain Syed — one person accountable from diagnosis to production.
Where Online Stores Get Stuck
Slow Store, Lost Sales
App bloat, render-blocking scripts, and heavy templates cost you visitors before they ever see a product.
Checkout Friction
Complex checkouts, surprise costs, and poor mobile UX leave buyers with items still in the cart.
Data Trapped in the Admin
Numbers live in Shopify, the numbers you need live in a spreadsheet, and somebody rebuilds the gap by hand every week.
Manual Order & Stock Work
Inventory reconciled by hand, stockouts found after they cost you an order, fulfilment status copied between systems.
Multi-Store Chaos
Several stores, several currencies, several exports — and no single view of what the business actually did this month.
The Platform Won't Do It
The feature you need does not exist as an app, and the workaround has become the bottleneck.
What I Do
Three levels of engagement. Most clients start at the first and move up as the return becomes obvious.
Optimise — make the store you have perform
Speed & Core Web Vitals
Diagnose the real bottleneck first — app overhead, render-blocking resources, image weight, or Liquid template cost — then fix that, rather than working through a generic checklist.
Checkout, Mobile UX & Conversion
Reduce friction where buyers actually drop off: checkout steps, product page structure, CTAs, and touch-first mobile flows — driven by analytics and real behaviour, not opinion.
Automate — remove the manual work around it
Reporting Pipelines & Custom Dashboards
Scheduled sales, inventory, and margin reports pulled straight from the Shopify Admin and GraphQL APIs — delivered as email, spreadsheet, or a live self-updating dashboard your team opens instead of asking you.
Inventory, Order & Fulfilment Sync
Webhook-driven pipelines that keep stock, orders, and fulfilment status consistent between your store, your suppliers, and your back-office — built to survive rate limits, retries, and out-of-order delivery.
Multi-Store & Cross-Platform Data Layers
One reporting API over several stores and platforms (Shopify, WooCommerce, marketplaces), so the business has a single set of numbers instead of four exports that disagree.
Alerting & Bulk Catalogue Operations
Stockout and store-speed alerts that reach you before a customer does, plus bulk catalogue work — AI-assisted product descriptions, price monitoring, mass updates — run as safe, resumable jobs.
Bookkeeping & Payment Reconciliation
Automated matching of payouts, fees, and refunds against orders — with receipt capture and export shaped for your accountant rather than for a generic template.
Build — when the platform cannot do it
Headless & Custom Storefronts
Next.js, Astro, and React storefronts on top of a commerce backend — for catalogues, merchandising, or performance requirements a theme cannot reach.
Payments & Checkout Systems
Stripe and Stripe Connect integrations, multi-currency checkout, subscriptions, split payouts, and identity verification (KYC) — built and operated as production payment flows.
Marketplaces & Auction Platforms
Two-sided platforms with real-time bidding or booking mechanics, seller onboarding, payouts, and the moderation tooling that keeps them running.
Admin Back-Offices & Internal Tools
The system the people running the business actually use all day: order oversight, catalogue management, customer records, role-based access, and reporting in one place.
Platforms I Work With
Shopify
Admin & GraphQL APIs, webhooks, bulk operations, Liquid themes, app overhead
WooCommerce
REST API integrations, plugin and query performance, server-side fixes
Custom & Headless
Next.js, Astro, React, Python and Node APIs, PostgreSQL, Stripe

Frequently Asked Questions
+ Do you only optimise stores, or can you build ecommerce features too?
Both. The work runs from targeted store optimisation (speed, checkout, conversion) through automation and integrations (order and inventory sync, reporting pipelines, custom dashboards) to full custom builds — headless storefronts, payment and checkout flows, marketplaces, and admin back-offices.
+ Can you automate Shopify reporting and inventory workflows?
Yes. I build Python pipelines against the Shopify Admin and GraphQL APIs — scheduled sales and inventory reports, multi-store data consolidation, stockout alerting, webhook-driven syncs, and self-updating dashboards. Bulk operations and cost-aware query design keep these stable at volume rather than breaking on rate limits.
+ Can you fix slow Shopify stores?
Yes. I diagnose the real bottleneck first — render-blocking resources, app overhead, unoptimised images, or Liquid template cost — then fix what is actually causing the delay rather than applying a generic checklist.
+ Do you build custom storefronts and checkout flows?
Yes. I build headless and custom commerce systems with Next.js, Astro, and React — including payment integrations (Stripe, Stripe Connect), multi-currency checkout, marketplace and auction mechanics, identity verification, and the admin back-office that runs them.
Ready to fix what your store cannot do yet?
Audits and focused fixes typically ship in 3–10 days. Larger automation and build work is scoped and quoted up front.
