You will get a Stripe subscription flow audit from payment to customer access
Project details
Stripe can report a successful payment while your app leaves the customer on the wrong plan, fails to unlock access or stores a different subscription state.
I will trace one agreed subscription flow from Stripe Test Mode through the webhook, backend and database to the result the customer actually sees. You receive up to six reproducible tests, censored evidence, a prioritized issue list and the minimum fix recommended for each finding.
This is a focused diagnostic for an existing SaaS built with React, Next.js, Node.js, Supabase, Firebase or a similar stack. It is not a generic code review and does not require production credentials.
Scope: one subscription flow, up to six test scenarios, a prioritized findings report, censored evidence and a clear map of where payment and customer access diverge.
Not included: code changes or deployment; new Stripe integration; Stripe Connect, marketplace payouts or tax architecture; multiple products, plans, environments or applications; compliance certification or a guarantee that no defect exists outside the tested scope.
Introductory price available for the first five projects.

About David
Stripe & Supabase Expert - Webhooks, Subscriptions, Fast Fixes
Carino, Spain - 6:06 am local time
What I handle:
- Bug fixes: Flutter/Dart apps, Python scripts, JS/TS, REST APIs
- Backends: Cloudflare Workers, D1, Supabase, Stripe integrations
- Automation: web scrapers, data processing, API integrations, bots
- Trading tech: MQL4/MQL5 Expert Advisors and indicators (MT4/MT5)
How I work:
1. You describe the problem (repo access or code snippet helps)
2. I confirm scope and a fixed price - no hourly meters running
3. You get the fix + a short video showing it working
4. You approve when satisfied. That's it.
Working languages: English, Spanish, Galician. I'm also happy to handle all written communication in German, French, Italian, Portuguese or most other European languages - whatever is most comfortable for you.
I keep scope tight and communication fast (responses within the hour, European timezone). If I can't fix it, I tell you upfront - no wasted time.
