Selected work

Stores that needed more than a theme and an app.

What the brief was, what I built and how I proved it worked.

2400 mmlive price
Made-to-measure worktops · Denmark, Danish and English

A worktop price calculator that is right to the øre

Customers design a custom-cut worktop, see the exact price as they go, and check out. Every order carries each choice, a technical drawing and the right freight weight.

504 / 0price checks against the live store, zero mismatches
Search 14,400 watchesfitsfitsno
Luxury watch winders · US store, client in Australia

A 14,400 watch compatibility search, with no backend

26 design mockups turned into a fully editable theme, and a search that tells a buyer in about a second whether a winder fits their watch.

Custom photobooks · Mexico, Spanish store

A paid membership the cart gets right

Members save 40% across the store. The cart now shows what joining is worth, keeps every price right as items change, and tracks each member’s lifetime savings.

Supplements · United States

A relaunch, then a measured SEO and AI visibility lift

A store pivoting to 58 supplements, rebuilt in days for launch, then made readable to search engines and AI assistants, with a before and after for every change.

47.9 to 79.9SEO and AI visibility score across 31 pages

Florist, local delivery · United States

The cart that kept reloading

A florist’s new theme was ready, but their delivery date app made the cart flash and reload. I found the loop inside the app’s own code and fixed it with one small change to the theme.

4 to 0page reloads, and the new theme could launch

A 36 question quiz with no quiz app

A two-part Ayurvedic assessment that scores each answer, recommends products for the result and sends every lead to Klaviyo, all editable from the Shopify admin.

★★★★★
“I have been using Fiverr for years and this has genuinely been one of the best experiences I have had on the platform. ... What I appreciated most was that he cared about the final result and not just finishing the order.”
★★★★★
“Hafiz felt like an extension of my team providing valuable and timely support. Hafiz even assisted on completing a task on time in the last 30mins leading up to our store launching on Shopify.”
★★★★★
“Hafiz built out a set of custom cart drawer blocks for our membership program ... Everything works the way we spec’d it. He also set us up properly with GitHub instead of editing theme files directly, which I appreciated.”

“Best Shopify Freelancer. It’s always a pleasure working with Hafiz. His work is always perfect, he recommends solutions and delivers always on time. We worked on multiple shopify projects together and I wouldn’t choose another one.”
★★★★★
“Hafiz did an outstanding job resolving a complex compatibility issue between two apps on my Shopify store, which the respective app developers were unable to solve themselves.”

Root causes

Bugs I’ve tracked down that others couldn’t.

A lot of my work starts where another developer stopped. A few of the real causes I have found, in plain English.

Coffee roaster, US

Prices showing $0.00, seemingly at random

Cause
The price block applied the money filter to a translation key that did not exist, so every product with variant prices rendered zero. Fixed-price products looked fine, which made it look random.
Fix
Rewrote the price block with the right keys and proper sale price handling.
Supplement brand, US

Blurry product photos on phones

Cause
The image size hint told the browser each photo would fill half the screen, so phones downloaded a picture half the size they needed.
Fix
Corrected the sizes so phones load a sharp image, with no extra weight on desktop.
Watch accessories brand, US

Every colour added the first colour to the cart

Cause
The custom colour picker never told the theme which variant was chosen, so the hidden add to cart field kept the first one.
Fix
Synced the variant, price and URL directly from the picker.
Show 3 more
Florist, US

The cart kept reloading on a new theme

Cause
A delivery app reloaded the page whenever its widget went missing, and the new theme kept replacing the cart markup the widget lived in.
Fix
Added one stable placeholder for the app to mount into. Reloads went from 4 to 0.
Bedding brand, US

Add to Cart invisible on mobile

Cause
The sticky buy bar sat outside the wrapper that set its colours, so the button rendered white on white. An accessibility widget covered what was left.
Fix
Scoped the colours correctly and moved the widget out of the way.
Worktop maker, Denmark

The order backend was using months-old prices

Cause
The custom app was missing one API permission, so it quietly fell back to a hardcoded copy of the prices. Nobody noticed, because the copy matched until prices changed.
Fix
Added the permission and made the fallback impossible to miss.

Process

How I work, every time.

Your live store keeps selling while I work. You see everything before it goes live.

  1. 01

    Plan

    A short written plan with phases, a fixed price and what done looks like. Nothing starts until you approve it.

  2. 02

    Build on a copy

    I work on a duplicate of your theme with Shopify CLI and GitHub. Your live store is never touched while I work.

  3. 03

    Prove it

    Every change gets before and after proof on desktop and mobile. Even invisible changes, like structured data, get evidence.

  4. 04

    Launch and support

    You check everything on a preview link. I publish once you are happy and stay on hand after launch.

About

Hi, I’m Hafiz.

I started writing software in 2015. I spent almost five years building a production accounting platform in Ruby on Rails, worked on Shopify Plus stores at FullStack Labs, and have run my own Shopify practice since 2021, with clients in 24 countries.

My Fiverr tagline has said the same thing for years: honesty and transparency is the key. I tell you what something will cost before I start, I explain every fix in plain English, and I say no to work I cannot do properly.

Things I build for myself.

Running my own apps keeps my client work sharp. I run the servers, the billing and the testing myself.

FAQ

Questions clients usually ask.

Do you work on Shopify Plus stores?

Yes, including checkout extensions and Plus-only features. I will also tell you honestly when something needs Plus and when it does not.

Will you work on my live store?

No. I work on a copy of your theme using Shopify CLI and GitHub, send you a preview link, and only publish once you are happy.

How do you price?

Small fixes have a fixed price. Bigger builds start with a short written plan, then a fixed price per phase, so you know the cost before work starts. Care plans are a flat monthly fee.

Can you build it without another monthly app?

Often, yes. Configurators, bundles, quizzes and pre-orders can usually live in your theme, so you own them and pay no monthly fee. When an app really is the better choice, I will say so.

What time zone are you in, and how fast do you reply?

Lahore, Pakistan (UTC+5). My day overlaps UK and European mornings and Australian afternoons, and I usually reply within a few mins on working days.

Do you work with agencies?

Yes. I can work under your agency on your clients’ stores, with the same process and the same proof.

Who owns the code?

You do. Everything lives in your theme and, if you like, in your own GitHub repository.

Can I hire you through Upwork or Fiverr?

Yes. If you already use either platform you can hire me there on the same terms. The links are just below.

Contact

Got something your theme or apps can’t do?

Tell me what you are trying to build or fix. The quote form takes about a minute, and I reply within 24 hours with honest next steps, even when the answer is that you do not need me.

What can I help with?

You will hear back within 24 hours.
