Start here

I help Shopify and WooCommerce stores fix slow pages, broken functionality, and conversion-blocking issues.

Most engagements start the same way: something is slow, something broke after an update, or the checkout is quietly losing people. I find the cause, fix it, and show the before and after.

Who it is for

Shopify and Shopify Plus brands with a live store and real orders
WooCommerce and WordPress sites that have outgrown their build
Agencies that need a senior engineer behind their designs

What gets fixed

Slow pages. Core Web Vitals, render-blocking scripts, image and theme bloat.
Broken functionality. Theme and app conflicts, failing plugins, checkout and integration errors.
Conversion blockers. Mobile interaction patterns, product pages, and tracking that does not match the real checkout journey.

How it runs

Technical review of the store and its stack
A written plan: what is wrong, in priority order, with effort
Implementation on staging, reviewed, then shipped
Verification with before and after numbers, plus handover

03 / problems solved

01 — Cosmo Technologies

How a Shopify Plus store improved its storefront and release process

Client type: DTC brand on Shopify Plus
Role: Lead Web Engineer, team of three

Request similar work ↗

Problem

Storefront work and releases had outgrown a single-developer setup, and the product and activation pages needed functionality the base theme could not carry.

What I changed

Took ownership of the Shopify Plus theme. Built custom sections and Shopify 2.0 templates for the JrTrack 5 product and activation pages, added Recharge subscriptions and checkout validation, and put code review and release QA in front of every deploy.

Stack

Shopify Plus · Liquid · Shopify 2.0 · React · Recharge · GA4 · GTM

3 developers led Plus Shopify tier QA on every release

02 — Dewitt Law Firm

How a law firm connected WordPress, Shopify, tracking, and automation

Client type: Professional services firm
Role: Web Engineering Lead

Request similar work ↗

Problem

Two platforms, WordPress and Shopify, ran side by side with SEO and tracking problems and a lot of manual operations work behind them.

What I changed

Took both platforms end to end: design implementation, theme and plugin work, H1 and Search Console corrections, robots.txt, CTA improvements, analytics, and AI-assisted workflows that cut manual operations work.

03 — Creative Dreams Agency

How we reduced page-load time by 30% across a multi-platform web stack

Client type: Digital agency, Melbourne
Role: Full-Stack Developer, 7 years

Request similar work ↗

Problem

Client sites were spread across six platforms, each with its own theme and build. Pages loaded slowly and every fix had to be reinvented per platform.

What I changed

Built custom WordPress and Shopify themes and plugins and React front ends, then ran one optimization pass over assets, scripts and templates that could be repeated on any of the six stacks.

WordPress · Shopify · React · Webflow · Framer · Go High Level

30% faster page loads 6 platforms covered 7yr engagement
