React Native Release Rescue

A clear path to your next React Native release.

For agencies, fractional CTOs, and product teams. I investigate a blocked release, scope the repair, and hand back changes and instructions your engineers can use.

A focused release problem

An existing app. One obstacle to shipping.

Release problems can persist in capable teams. I focus on a specific blocker when you have access to the app and a technical owner ready to take the work forward.

Potential fit, subject to assessment

  • A previously working release build now fails.
  • Local and CI builds produce different results.
  • A dependency change introduced a release blocker.
  • Signing or provisioning prevents a build or upload.
  • The release version crashes on startup while development builds work.
  • An SDK or build-tool compatibility issue prevents an update.

Work that fits the team responsible for delivery.

  • Agencies and delivery leads

    I work through your technical contact, keep updates concise, and return maintainable changes to your team. Client-facing communication happens only as agreed.

  • Fractional CTOs

    I establish what is broken, whether a targeted repair is realistic, and what your team needs to reproduce the release. Scope and responsibility are agreed before work begins.

  • SaaS CTOs and technical founders

    I build on your engineers’ findings and focus access and onboarding on the blocked step. Your team receives the changes, verification results, and remaining actions.

Two stages. A decision between them.

Diagnose first. Agree the repair before it starts.

01 / Understand the blocker

Release diagnosis

$1,500USD · diagnosis only

One application, one affected platform, and one agreed release blocker.

Effort cap
Up to 8 total hours
Written findings
Within 5 business days

Investigation, documentation, and calls count toward the total. The delivery window begins once the scheduled start and required access are in place.

I reserve time within the effort cap for the written brief and handoff.

A written diagnosis brief, including remaining uncertainty and the recommended next step. I provide a repair quote when a suitable repair can be scoped.

02 / An accepted, quoted repair

Scoped release rescue

$3,000USD total · starting price

The $1,500 diagnosis fee is credited toward the same agreed rescue project.

We agree the remaining price, technical milestone, test coverage, and schedule before implementation.

I accept repairs that can reasonably fit within 1–2 scheduled weeks.

I make the agreed changes, run the agreed checks, and document how your team can reproduce the result.

Diagnosis does not guarantee a simple fix or acceptance of the repair. If broader work is needed, I provide a separate recommendation.

At the starting price: $1,500 diagnosis + $1,500 additional repair = $3,000 total. If you stop after diagnosis, the fee is $1,500.

What you keep after diagnosis.

You receive these findings even if we stop after diagnosis, so your team can decide what to do next.

  • Observed failure

    Where the release stops, the reproduction attempts, and what I could and couldn’t reproduce.

  • Build requirements

    Relevant dependency and toolchain versions, configuration, and constraints identified during the investigation.

  • Evidence and uncertainty

    Explanations investigated, what the evidence supports, and what remains unknown.

  • Recommended next action

    A targeted repair if feasible, a broader migration if needed, or the next useful investigation step.

Start with the blocked step.

I’ll assess fit before we arrange access or schedule diagnosis.

Discuss a blocked release

How the stages are scheduled.

  1. Scheduled diagnosis

    Findings within 5 business days once the scheduled start and required access are in place.

  2. Your decision

    Review the brief and, if a repair fits, decide whether to accept the quote.

  3. Accepted repair

    A separate start date, technical milestone, and checks agreed before implementation.

  4. Technical handoff

    Reviewable changes, verification results, and release instructions for your team.

Diagnosis and repair are scheduled separately. I confirm dates with you before each stage; repair does not start automatically after diagnosis.

One agreed technical contact, a focused kickoff, and a closing handoff.

Targeted changes

A quoted repair may include necessary dependency or SDK changes. A complete dependency upgrade requires a different engagement.

A defined boundary

Whole-app modernization, feature development, extensive native rewrites, and ongoing maintenance require a different engagement. Account disputes and store-policy appeals are outside this technical package.

A technical endpoint

Agree what “done” means before the repair.

Completion is an agreed technical milestone. Depending on the blocker, it could be:

  • A reproducible release build.
  • A signed release artifact that passes the agreed checks.
  • A successful upload to an agreed testing destination.
  • Resolution of a documented technical submission failure.

Building, uploading, store review, and public rollout are distinct stages. Delivering a build does not make the app publicly available. Store approval and review timing are outside my control.

How upload and store release differ

Checks agreed in the quote

The quote defines checks for agreed devices and environments, including appropriate checks for the other platform if shared changes could affect it.

Your accounts. Agreed authority.

Client accounts remain client-owned. Store submissions and public releases require explicit agreement with the client.

The repair handoff

A release your team can understand and maintain.

  1. Reviewable changes

    Code and configuration changes tied to the agreed blocker.

  2. Repeatable release steps

    Documented build requirements and instructions for reproducing the result.

  3. Verification results

    What passed, what was checked, and the devices or environments used.

  4. Remaining actions

    Known limitations, outstanding steps, and clear responsibility after delivery.

  5. Reverting the changes

    Guidance for reverting the repair where applicable.

Before you get in touch

Practical answers about the engagement.

Is this suitable for an existing app that no longer builds?

A failed release build in an existing app is a potential fit. Send the affected platform, a brief error summary, and the last successful release if known. I’ll assess the scope with you.

Can the engagement cover both platforms?

The starting scope covers one blocker on one affected platform. If shared code or configuration may affect the other platform, the quote includes appropriate checks. Repairing separate blockers on both platforms needs an explicitly agreed scope and price.

What if the repair requires a larger migration?

I explain why the work exceeds a targeted repair and recommend a separate engagement. Your diagnosis brief still records the findings, uncertainty, and next step.

Is the diagnosis fee credited toward repair?

The $1,500 diagnosis fee is credited toward the same agreed rescue project. At the starting price: $1,500 diagnosis + $1,500 additional repair = $3,000 total. If you stop after diagnosis, the fee is $1,500. Implementation proceeds only after we agree the quote.

What access is needed?

We agree access to relevant source, build and CI configuration, dependency versions, and redacted failure evidence. Signing or store access is arranged only when needed, using client-owned accounts. A summary is enough for the initial inquiry.

Does this include store submission or approval?

Submission can be included when explicitly agreed with the client. Building, uploading, store review, and public rollout are separate stages. Store review timing and approval remain with Apple or Google.

Can you work through my agency?

Yes. I work through your agreed technical contact and hand changes and release instructions back to your team. Client-facing communication happens only as agreed.

A short email to start

Where does your release stop?

A short summary is enough to check fit. Share what you know; missing version numbers or build details shouldn’t stop you from getting in touch.

Include what you know:

  • Role and company
  • App or store link (if available)
  • Affected platform and failing release step
  • React Native version and Expo/EAS use (if known)
  • Brief error summary
  • Last successful release and desired timing
