How AI-native orchestration helps here
AI-native orchestration helps map state machines, webhook behavior, retries, idempotency, reconciliation, dashboard/admin flows, and test coverage before touching revenue-critical code.

Payments
Stripe and SaaS Systems Engineering
Payments are where weak backend design becomes expensive. I build Stripe-backed systems with the boring but necessary pieces done correctly: retries, idempotency, webhooks, reconciliation, operator visibility, and product flows that do not fall apart once real money is involved.
What I handle
Subscription, invoicing, or Connect architecture across backend and product surfaces.
Webhook ingestion with retries, deduplication, idempotency, and failure handling.
Admin visibility for payment state, onboarding gaps, and payout operations.
Integration with existing Next.js, NestJS, Node.js, or Flutter applications.
What I usually build
- Subscription platforms, customer billing, and portal flows.
- Connect onboarding, payouts, and business operations workflows.
- Payment pipelines that need durable retries and state integrity under failure.

Questions clients usually ask before starting
Can you fix an existing Stripe integration that is already live?
Yes. That is common. I usually start by mapping the current payment state model, webhook flows, and failure cases, then harden the weak paths without breaking revenue-critical behavior.
Do you handle only Stripe, or the whole SaaS backend around it?
The whole backend around it. Stripe is only one part of a real billing system. The product logic, auth, retries, support tooling, and operational visibility matter just as much.
