Daramola was incredibly helpful with my website payment problems. He was obviously very well-informed and has answers to all my questions. He's an absolute professional - you really feel like you're in good hands. I'll definitely be using his services again.

The real problems often happen afterward. A webhook arrives twice. A database update fails halfway through. A customer is charged but receives no access. A canceled subscription remains active inside the application. Stripe shows one payment status while the internal system shows another.
I help SaaS companies, marketplaces, and online businesses prevent and fix these problems.
My work covers the complete payment flow, from Stripe Checkout or Billing to webhooks, application logic, database records, customer access, fulfillment, refunds, and internal operations.
I can help with:
- Stripe payment flow audits
- Checkout and subscription debugging
- Stripe Billing and subscription lifecycle handling
- Signed webhook implementation
- Idempotency and duplicate event protection
- Failed payments, cancellations, refunds, and upgrades
- Multi-currency payment issues
- Payment status and customer access synchronization
- Third-party API and automation integrations
- Existing Stripe integrations that need to be understood or repaired
I am also a senior full-stack developer, so I can investigate problems outside Stripe when the payment flow depends on the wider application.
My core stack includes:
- Next.js, React, TypeScript, and JavaScript
- Node.js APIs and backend services
- PostgreSQL, Supabase, and MySQL
- Authentication, roles, and permissions
- Admin dashboards and internal tools
- AWS, deployment workflows, testing, and documentation
- Mobile Application development with React Native
- Web Development
When taking over an existing application, I first trace how money and payment events move through the system. I review the relevant webhook handlers, APIs, database writes, authentication rules, subscription logic, and failure scenarios before changing the code.
I then make focused, reviewable improvements. Depending on the project, this can include tests, safer retry handling, clearer event logs, recovery paths for failed processing, and documentation for future maintenance.
I communicate clearly, work carefully around live systems, and raise concerns when a shortcut could lead to duplicate charges, lost access, incorrect subscription states, or difficult production failures.
If you have a payment issue, send me the Stripe event involved, what your application did, and what it should have done. That is enough to start.
