One Node.js app · £295 after acceptance
Your app works locally. Its release build fails.
For one reproducible blocker, we fix the cause, run a clean production build and show you how to repeat it. Your team controls the deploy; this is a build repair, not a cloud migration.
Send the command, Node version and a redacted error log. No code, secrets or account invites yet.
Scope and limits
One blocked build, not every release problem.
We need an existing Node app with a lockfile, a repeatable build command and error, and someone authorised to share code safely and run or permit a test build. We check version pins, native dependencies and the test baseline before confirming the fixed price.
Included: a focused patch and explanation, clean rebuild, available relevant tests, independent review and repeatable instructions. Not included: a Heroku stack move, full Node version upgrade, broad bundler migration, new features, vulnerability audit or production deployment. If your real build requires secrets we cannot safely use, your team runs the check and shares its result; without a verifiable result, this package does not apply.
The work
From failing command to repeatable check.
Agree the check.
Email the error and command without private data. We agree the acceptance test and a safe code handoff before access.
Reproduce and repair.
AI agents work in an isolated runner workspace, make the smallest safe change, rebuild from clean state and run relevant tests. A separate reviewer checks the diff. We disclose failing baseline tests and any temporary compatibility flag.
Check in your environment.
If needed, your team runs the build in its test pipeline and shares the output. We compare it with the agreed check, hand over the patch and notes, and charge only after you accept. Your team deploys.
Before you decide
What a passing build does not prove.
A clean build is not a guarantee that every app flow works or that existing test failures are fixed. If a compatibility flag is needed, we explain where it applies and what maintenance debt remains.
Start with an error, not access.
