Payment flows that keep working after checkout.
I build payment integrations around the full lifecycle, including billing states, webhooks, subscriptions, invoices, refunds, failures, operational visibility, and customer communication.
A successful payment is only one state in the system.
Real payment workflows must handle pending states, delayed confirmation, failed renewals, duplicate events, refunds, cancellations, disputes, account verification, reconciliation, and the actions your team needs to take when something changes.
What can be built.
Stripe Checkout integration
Subscription billing, plans, and recurring payments
Custom pricing and plan logic
Invoices and payment links
Stripe Connect for marketplaces and platforms
Customer billing portals
Robust webhook processing
Refund and cancellation workflows
Failed payment handling and dunning
Payment status reporting
Integration with PayPal, HitPay, Xendit, and other supported gateways
Payment state should come from reliable events, not assumptions in the browser.
I design payment workflows with server-side verification, idempotent processing, clear status models, operational logs, and recovery paths for events that arrive late, fail, or repeat.
Frequently Asked Questions
Can you add Stripe to an existing application?
Yes. I can integrate Stripe into an existing product, review the current implementation, improve webhook handling, or extend the billing model.
Do you work with subscriptions?
Yes. Subscription work may include plans, trials, upgrades, downgrades, renewals, cancellations, failed payments, invoicing, and customer billing portals.
Can you build Stripe Connect for a platform or marketplace?
Yes, when the business model and account flow are clearly defined. Connect projects require careful decisions around onboarding, account ownership, charges, fees, payouts, refunds, and compliance responsibilities.
Do you support payment gateways other than Stripe?
Yes. I have experience with additional payment providers, and the right choice depends on the country, business model, currencies, payment methods, and operational requirements.
