It works on your machine. It is failing for your users.
Production bugs are expensive because the team burns days reproducing instead of diagnosing. I work from the evidence you already have — crash reports, logs, the failing build — and tell you where the fault actually is.
Diagnosis
US$149
Delivery target
24–48 hours
Optional implementation
US$499+
Want the fix implemented? Implementation starts at US$499 and is quoted against the diagnosis.
What you get
- The probable root cause, with the evidence that points to it.
- What to verify first if the evidence is not conclusive.
- A correction plan in priority order, separating the stop-the-bleeding fix from the real fix.
- Risk notes: what could regress, and what to watch after shipping.
Who this is for
Teams with a shipped iOS or React Native app failing in production.
What this covers
- Crashes and startup failures
- Regressions introduced by a release
- Login, session and token-refresh failures
- Push notifications not arriving or not routing
- Purchases, subscriptions and restore flows
- Networking and API integration failures
- iOS and React Native errors visible only in production
What I need from you to start
- Crash reports, stack traces or logs — Xcode Organizer, Crashlytics, Sentry, whatever you use.
- Reproduction steps if you have them, plus affected OS and device versions.
- The affected build number and what shipped in it.
- Read access to the relevant repository, if the diagnosis needs to reach the code.
Scope and limits
- The diagnosis depends on receiving sufficient evidence. Without crash reports, logs or a reproduction, I can narrow the search but not conclude — and I will say so rather than guess.
- A broader fix or refactor is quoted separately.
- I do not take incident-response retainers through this page.
How it works
From blocked to a decision you can act on
No discovery calls to sell you a retainer. You send evidence, you get a written answer.
- 01
You send the evidence
The rejection message, the crash report, the failing build — whatever you already have. No forms, no lead-nurturing sequence.
- 02
I diagnose within the stated window
I work from your artefacts and, when access is granted, your code and App Store Connect record. The window starts when the evidence is complete.
- 03
You get a written plan
Probable cause, the correction plan in priority order, and — for App Review cases — a drafted reply you can send as-is or edit.
- 04
Implementation only if you want it
If you want me to make the changes, that is quoted separately against the plan you already have. Never a surprise on the invoice.
