I'm Muhammad Yasir Majeed, a Senior E-commerce Developer with 7+ years of experience creating custom digital commerce experiences.

I work across Shopify, Magento 2 and WordPress. Most of what I do is custom: theme development and customization, complex store functionality, integrations, UX improvements and performance optimization.

I don't just build websites. I create high-performing e-commerce experiences focused on design, usability, performance and conversions.

Case studies

How these features came together: the problem, the solution, the technology and what the shopper ends up with.

Problem

Pillow covers are bought in combinations, and it is hard to judge from separate product photos how a set will look together on a sofa.

Solution

An arranger where shoppers pick a room scene or upload their own photo, then place pillows on it and resize, rotate, duplicate or remove them.

Technology

Shopify, Liquid and JavaScript, with the store's live products, sizes and prices feeding the tool.

Final experience

Shoppers filter by color and size, style the scene and see a running subtotal for the arrangement they have built.

See it live on coteriebrooklyn.com

Problem

Subscribers want to choose what arrives. A fixed subscription product can't offer that choice.

Solution

A build-a-box flow where shoppers pick the products for their box and subscribe to that selection.

Technology

Shopify, Liquid and JavaScript, connected to the store's subscription setup.

Final experience

Choosing products and subscribing happen in the same place, as one decision.
