I will fix revenuecat capacitor supabase subscription testflight capacitor integration
Augustus
About this gig
Your app works in dev but subscriptions break in TestFlight. Anonymous RevenueCat users, subscription sharing across accounts, sandbox entitlements that won't clear, or a Capacitor wrapper that never got Apple's guidelines right. Sound familiar?
I fix existing RevenueCat, Capacitor, and Supabase setups. Not a from-scratch rebuild, a correction of what's already there so it ships.
What I check and fix:
- RevenueCat App User ID + login/logout flow
- Subscription sharing between accounts (entitlement leaks)
- Sandbox vs production entitlement mismatches
- Capacitor wrapper config for Apple submission
- Supabase auth tied correctly to RevenueCat identity
- Restore purchases + purchase transfer behavior
- App Store guideline blockers (3.1.1, 4.2, 5.1.1)
You get a working TestFlight build your subscriptions actually behave correctly in, not just one that compiles.
Message me before ordering with your current setup (RevenueCat dashboard access helps) so I can confirm scope before you pay for the wrong tier.

Full-stack developer specializing in AI-assisted development, vibe coding and traditional software engineering. I help businesses audit, fix, and scale apps built on platforms like Base44, plus custom stacks (React, Node, Supabase, Stripe). My work covers production-readiness audits, bug fixes, API and payment integrations, and finishing MVPs that stalled mid-build. I blend hands-on coding with practical AI tooling for fast, reliable results without sacrificing quality. Clear communication, honest technical assessments, and clean handoffs, every project treated like production from day one.

FAQ
Do you build the app from scratch?
No. I fix and finish existing RevenueCat, Capacitor, or Supabase setups that are already mostly built.
What if my app has no RevenueCat issues, just a Capacitor/TestFlight problem?
Fine, message me first with the specifics so I scope the right tier before you order.
Do I need to give you my Apple Developer account credentials?
No. I work as a collaborator inside your own accounts. I never need your passwords.
What's included in the Basic audit?
A live review of your RevenueCat dashboard and Capacitor config, plus a written report on what's actually broken and why.
Can the Basic tier turn into Standard or Premium later?
Yes, the audit fee counts toward the next tier if you upgrade within 7 days.Yes, the audit fee counts toward the next tier if you upgrade within 7 days.
My subscriptions work in sandbox but weirdly renew for free in TestFlight, is that you?
Yes, that's a classic sandbox/entitlement mismatch. Standard tier covers it.
Do you handle Apple rejections like Guideline 3.1.1 or 5.1.1?
Yes, in the Premium tier, including help through resubmission until approved.
What do you need from me to start?
Repo access (or collaborator invite), RevenueCat dashboard access, and a short description of what's broken.
Does this include building a Capacitor wrapper from a Base44/Lovable/Bubble app?
If it's already wrapped and needs fixing, yes. If you need a wrapper built new, message me first.
What if you can't identify the root cause?
That's still useful information and part of the deliverable, I'll tell you plainly and won't pad the report to justify the fee.
