SOUND FAMILIAR?

Your storefront has outgrown the plugins holding it together.

Off-the-shelf apps almost do what you need — but never quite.
Inventory, orders, and returns drift out of sync across tools.
Someone reconciles storefront data by hand every week.
You pay for a stack of apps that don't talk to each other.
The store can't scale past the plugins holding it up.
You need logic no Shopify app in the store offers.

FAQS

Before You Get Started

What does Stackworx do?

We build and take ownership of the systems your business runs on: custom Shopify apps, Ruby on Rails platforms, third-party integrations, and practical AI workflows. Most clients come to us when off-the-shelf apps and quick fixes stop scaling.

Do you only build new products, or can you take over an existing system?

Both. A large part of our work is taking over existing Rails and Shopify codebases, stabilizing them, and then extending them. We start with a technical audit so you know exactly what you have before anything changes.

How do you add AI to a business that already has software?

We add AI inside the systems you already run rather than bolting on a separate tool. Typical work includes content generation, document and data extraction, product recommendations, and support automation, shipped as a focused AI Integration Sprint with measurable outcomes.

How do engagements usually start?

Most clients start with a Technical Audit or an AI Integration Sprint. From there we move to an MVP build or a dedicated product team on a monthly retainer, depending on how much ongoing work you have.

Which industries do you work with?

Mostly ecommerce brands on Shopify and SaaS companies in PropTech, InsurTech, and FinTech. Our platforms have processed 32M+ transactions and serve 20,000+ real estate agents.

Where is your team, and how do you work with US clients?

Our senior engineering team is based in Lahore, Pakistan and works with US clients across time zones, with regular overlap hours, async updates, and long-term ownership of the systems we build.
