RUBY ON RAILS TAKEOVER & SUPPORT

Rails app takeover and long-term support for inherited apps.

For founders and operators who need someone to take over a Rails app after the original developer or agency moved on. We audit the codebase, secure access, stabilize production, then maintain and upgrade the app for the long term.

SOUND FAMILIAR?

You inherited a Rails app nobody on the team fully understands.

The developer who built it left, and the knowledge left with them.
The app runs on an old Rails or Ruby version you are afraid to touch.
Deploys are manual, risky, or only one person knows how.
Small changes break unrelated parts of the app.
Gems are outdated and security patches keep piling up.
You are not sure who has access to servers, keys, and accounts.

WHY CHOOSE STACKWORX

Rails is what we have shipped for 10+ years

We take over existing Rails codebases and keep them running. The work starts with understanding the app as it is, not rewriting it into what we would have built.

Understand before changing

We read the code, map the data model and integrations, and document how the app actually works before we change anything in production.

Upgrades without a rewrite

Old Rails and Ruby versions get upgraded in steps, with tests added around the risky parts, so the app keeps running while it moves forward.

Long-term ownership

After the takeover we stay on as the team that maintains, monitors, and extends the app, the way we do with long-term partners like Zentap.

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 we contract with US clients through Stackworx LLC, our Wyoming company. We work across time zones with regular overlap hours, async updates, and long-term ownership of the systems we build.
