Your Rails app is live. Your developer is gone. Something is broken.

You inherited a Ruby on Rails application that real customers depend on, and the person who built it is no longer around. Maybe the freelancer disappeared, the in-house engineer left, or the original agency moved on. Now the app throws errors you cannot explain, deploys make you nervous, and every quote you get to fix it assumes a full rewrite. You do not need a rewrite. You need a senior engineer who has seen this exact situation many times and can take ownership of it this week.

Let's Talk

What we do

We adopt the codebase as it is, no judgment about how it got here. The first phase is a read-and-stabilize pass, usually one to two weeks. We read the code at scale with AI tooling, map what the app actually does, find the live fires (the crashes, the silent data issues, the unpatched security holes), and put them out first. You get an honest written assessment: what is healthy, what is fragile, what is genuinely at risk, and what it costs to fix each.

From there we become the team. One named senior engineer fronts the relationship and stays on it, so there is no handoff to a junior who does not know your product. We backfill the missing test coverage so changes stop being scary, ship the fixes your users feel first, and only then talk about the bigger structural work. Old Rails version, no documentation, original author gone - that is the normal starting point for us, not a blocker.

Proof, not adjectives

This is what we do. Volodymyr has 17+ years of Rails depth, going back to authoring the first versions of products like MoveitPro (now 2,000+ moving companies, 40,000 daily users) and HappyCo (now a substantial PropTech company in the US). VeViDi has been the ongoing engineering team behind LionWheel, which today powers deliveries for 1,000+ businesses worldwide at 4.8/5 on G2 and Capterra.

The clearest rescue receipt is one we cannot name. We took over an inherited, live fintech product (under NDA) that had real customers and was shipping bugs to those users. We stabilized the Rails backend in place. It now runs with zero error alerts for months. That is the shape of the work: a buggy live product walked in, a quiet stable one walked out, no rewrite, no drama.

The economics

Rescue work used to mean putting a full team on a codebase for months. With senior judgment plus AI amplification, reading the code at scale and generating the test safety net happen in a fraction of that time. The cost math has also shifted in your favor: an in-house developer now costs salary plus a monthly AI tooling bill on top, while one senior engineer with AI amplification through us can land under the cost of that local hire alone, because we already run the AI tooling as our default workflow. Numbers depend on your market and scope, so we scope honestly before you commit.

Who this is not for

If your app is a two-week tweak you can hand to a freelancer or do yourself with a tool like Claude Code, you do not need us, and we will tell you so. If you want a body to fill a seat for six months with no defined outcome, we are the wrong shop. We take on rescues where senior judgment changes the result: a live product that matters to your business and cannot afford a guess.
