Payments and integrations are the part of a build where "mostly works" isn't good enough — a double charge or a lost webhook is a real customer and real money. I integrate the gateways (Stripe, PayPal, Razorpay and more) and connect your systems to each other, built idempotent and reconciled, the same way the money flows in my live booking platform. Remote, worldwide.
Integrations are judged on the failure cases — the timeout, the retry, the disagreement between two systems. Here's the integration work I build, with those cases handled, not hoped away.
Stripe, PayPal, Razorpay and others — checkout, saved cards, subscriptions and payouts, wired to the same money logic I run in production.
Reliable webhook handling with signature checks, retries and deduplication — so a delayed or repeated event never double-charges or loses an order.
Refunds, partial refunds and reconciliation against gateway settlements — so your books and the gateway actually agree.
Connecting your app to ERPs, CRMs, accounting, shipping and supplier feeds — REST, SOAP or GraphQL, kept in sync reliably.
Supplier and GDS connections for travel and booking platforms — the deep integration work I do every day. See travel work →
Every money operation idempotent and logged, so a retry is safe and there's always an audit trail when someone asks "what happened to this payment?"
An integration is trustworthy when it survives the network being flaky and the other system being down. Every build ships with that built in.
My live multi-GDS platform takes payments, applies markup, moves money between agent wallets and issues refunds — every day. Integration and payment reliability isn't theory for me; it's what I already operate.
What has to move between the systems, in which direction, and what happens when they disagree. We agree the scope and the edge cases up front.
The integration contract, the idempotency and retry strategy, and the reconciliation approach — decided before code.
The integration built behind a clean adapter, with webhooks, retries and logging, tested against the provider's sandbox.
Timeouts, duplicate events, partial failures and refunds — the money paths tested deliberately, not discovered in production.
Switch to live keys carefully, watch the first real transactions, and stay on to add providers or flows. See support options →

The server-side layer every integration lives in — auth, jobs and reliability, built for correctness under load.
A whole platform of payments and supplier integrations — the production system this reliability comes from.
How one system talks to many external providers at once — normalisation, failover, price drift and refunds.
