Dev4ager fixes bugs and untangles messy codebases, including abandoned projects and unreviewed AI-generated code. A short paid audit sizes the problem honestly; then we fix hourly, with a regression test on every fix so the bug stays dead.
What we do
Rescue work has one rule: stabilize before you beautify. We find what's actually broken (often not what it looks like), fix the bleeding, add tests around the critical paths, and only then clean up, so the app keeps running while it gets healthier.
- Bug diagnosis and fixes with regression tests attached
- Project takeovers: access recovery, audit, stabilization plan
- Cleanup of unreviewed AI-generated and freelancer-spaghetti code
- Dependency upgrades and security patching without breakage
- Error monitoring setup so future bugs announce themselves
- A written map of the codebase, so it's never hostage to memory again
How we work
- Audit. A few paid hours reading code and logs. You get an honest report: what's solid, what's risky, what it costs.
- Stabilize. Highest-impact fixes first, each with a test that proves it.
- Clean. Refactors module by module. The app never stops working.
- Hand back. Documented, monitored, and optionally on a care plan.
Stack we reach for
TypeScript React/Next.js Node.js Playwright Sentry GitHub
A great fit if…
- Something's broken in production and your last developer is unreachable.
- You vibe-coded an app that works, mostly, and want it made trustworthy.
- Every new feature breaks two old ones and nobody knows why.
Bug fixing FAQs
Our developer disappeared mid-project. Can you take over?
Yes, this is a third of our rescue work. We secure access and accounts first, audit what exists, tell you honestly what's salvageable, then stabilize before building anything new. Most abandoned projects are more recoverable than they feel.
How do you charge for bug fixes?
Hourly, with a short paid audit up front for anything non-trivial. The audit tells you the real size of the problem before you commit, no open-ended "we'll see" invoices. See hourly options.
Can you clean up AI-generated or spaghetti code?
Yes, unreviewed AI output is the fastest-growing category we rescue (here's why that happens). We add structure incrementally: tests around critical paths first, then refactors module by module, so the app keeps working throughout.
How do you make sure the same bug doesn't come back?
Every fix ships with a regression test that reproduces the bug and proves it's dead. Fixes without tests are just bugs on vacation.
