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Gems are outdated and security patches keep piling up.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.
