Custom storefronts for brands with real complexity

At PIVOT, I worked as part of small dev teams on custom Shopify Plus builds - third-party integrations, content templates, and ongoing feature work.

Timbuk2

Bags & accessories
Custom Shopify Plus Storefront - Built at PIVOT (Shopify Plus Agency Partner)

Timbuk2 is an iconic bag brand with a loyal customer base and a complex product catalog. At PIVOT, I worked on their custom Shopify Plus storefront as part of a small dev team over 14 months. My contributions included custom Liquid templates, responsive front-end implementation, structured data schemas, and integration work across their marketing and analytics stack including Klevu search and Elevar tracking. I also worked on their help center, eco/sustainability pages, store locator, and corporate page system.

Celluma

Health & wellness

Celluma makes FDA-cleared LED light therapy devices - a product that requires a content-heavy storefront with educational pages and a professional vs. consumer audience split. At PIVOT, I contributed 209 commits over the course of this project. My work covered content page templates, blog filtering with author views, Rebuy cart integration for free gift logic and variant backorder messaging, Klaviyo modal and form integrations with GA event tracking, and accessibility improvements including focus traps, alt attributes, and translations. I also worked on theme settings to scope changes between their US and international stores.

Beyond Client Work

A published app and a viral campaign

A published app I built on my own, and a campaign project worth mentioning.

FieldsRaven

Own product
My Own Shopify App - Live on the Shopify App Store

FieldsRaven extends Shopify's Metafields API to the storefront through an app proxy, enabling merchants to collect data on the fly and personalize their theme - functionality Shopify doesn't expose natively. Built with Ruby on Rails, I handle the full lifecycle: ideation, architecture, development, deployment, App Store review, and merchant support. Having a live app gives me platform depth that's hard to get from client work alone - I understand the API constraints, the review process, and how merchants actually use extended functionality in the real world.

Keurig Rivo Launch Campaign

Campaign build
Contest Web App - Built at Le Site (E-commerce Agency, Montreal)

For the Canadian launch of the Keurig Rivo espresso machine, I worked on a contest web app at Le Site, an e-commerce agency in Montreal. The app was delivered in 3-4 weeks from brief to launch, attracted hundreds of thousands of visitors, and generated over 30,000 social shares. I also automated the campaign's email build process, cutting production time from 8 hours to 2 hours using Middleman and the Google Docs API. This predates my Shopify focus, but it shows I can work on high-traffic, time-sensitive projects with tight deadlines.

How I Help

Ongoing Shopify Plus support without the agency layers

I spent nearly 3 years working on custom Shopify Plus storefronts at PIVOT, a Shopify Plus Agency Partner. Now I work directly with brands and agencies. I'm available for ongoing retainers, project-based work, or a mix of both, and I usually work on retainer so I can learn your theme, your integrations, and the edge cases that tend to show up at the worst times.

  • Ongoing backlog work, bug fixes, and theme cleanup
  • PDP and cart work: configurators, bundles, subscriptions, sticky ATCs, and size charts
  • Third-party integrations: Klaviyo, Yotpo, Rebuy, Klevu, Elevar, and Affirm
  • Landing pages, seasonal campaigns, and launch support
  • Structured data, SEO hygiene, and site speed improvements

What People Say

From the people I've worked with

I recently launched my Shopify store and I hired Karim to help with the development of the site. Karim did an amazing job with all of the projects I gave him and he exceeded all of my expectations. I was particularly impressed with Karim's communication, timeliness, receptivity to feedback, and attention to detail. He was very open to change and communicative about creative approaches we could take and the potential impact to the original estimate. I wholeheartedly recommend Karim.

Twice I got told I would have to compromise on the changes I wanted for my website, until I contacted Karim. He implemented a challenging filter change to my delight. If there are more cost effective, efficient and better ways to do what you are trying to achieve he will tell you.

Karim did an excellent job, he met and exceeded all expectations. He communicated clearly at each phase of the project.

Karim is a passionate developer that strives to better himself and improve his craft. He has helped OnlyGrowth with front-end development for Shopify sites. Karim is very responsive and communicates when he will be away or needs an extension. Unlike a lot of developers, Karim is also fairly good with estimating tasks and QA'ing his work prior to saying it is done.

Karim worked with us as a contractor for ~2 years. I was always impressed with his punctuality, organization, problem solving and ability to think outside the box. He was never afraid to push back and make suggestions which would always benefit the projects we worked on together.

Not only he would deliver quality work on time, but also made sure he was improving his source code while keeping it readable and maintainable. His eye for design and his constant curiosity was also very appreciated by our team.

About

A bit more context

I'm Karim, a fullstack Shopify developer based in Victoria, BC. I've been building for the web for over 17 years, with the last 9 focused on Shopify. Most recently I spent nearly 3 years at PIVOT, a Shopify Plus Agency Partner, where I contributed to custom storefronts for 20+ DTC brands as part of small development teams.

"Fast and flexible and dedicated to delivering work that fit our needs."

I’ve also built and published FieldsRaven, a Shopify app on the App Store that extends the Metafields API - so I understand the platform from the app side too, not just the theme side.

Before Shopify, I worked at the ALDO Group, worked on a high-traffic web app for Keurig's Canadian launch, and spent time at Doctors Without Borders managing their UAE web presence. I hold a B.Sc. in Computer Engineering and a Project Management certificate from McGill.

I work best on a part-time or retainer basis, consistent enough to understand your brand, flexible enough to not be overhead you don't need. I'm remote-first and have been for years. I take pride in the work and I'm in it for the long game. Good work leads to repeat business, and that's exactly how I want to grow.
