Stripe &
payments integration.
Stripe integration connects an application to Stripe for payments — one-off checkout, recurring subscriptions or marketplace payouts with Stripe Connect. I implement it with verified webhooks as the source of truth so the app's access rules always match billing state.
Payments are where bugs cost real money. I integrate Stripe subscriptions, one-off checkout and Stripe Connect marketplaces with webhook-driven state, so your app always agrees with what Stripe says.
What I build
Subscriptions
Plans, trials, upgrades, proration and a self-serve customer portal.

Technical approach
- →Webhooks as the source of truth, verified by signature and processed idempotently.
- →Access checks on the server based on stored subscription state.
- →Dunning and failed-payment flows configured before launch.
Frequently asked questions
Can you fix an existing Stripe setup?
Yes. I audit webhooks, subscription state and access checks, then fix gaps without disrupting current customers.
How long does a typical project take?
It depends on scope. A focused feature or fix can take days; a first production version of a product usually takes several weeks. I give a written estimate after a short discovery call.
Do you work with US companies?
Yes. I work remotely with startups and businesses across the United States and internationally, with overlapping working hours for calls and async updates in between.
