About this gig

Payment and third-party integrations can make or break your application. With over 6 years of backend experience, I specialize in wiring up complex, secure, and idempotent API integrations that don't fail under pressure.


What I can integrate for you:

  • Payment Gateways: Stripe (Subscriptions, Apple/Google Pay, Webhooks), Xendit, Midtrans, and custom local gateways.
  • Authentication: Strava OAuth, Google Sign-in, Firebase Auth, and secure session/token handling.
  • Communication & Mail: Automated email flows (Brevo, SendGrid), SMS, and push notifications.
  • Third-Party APIs: Any REST, GraphQL, or SOAP service.

Why work with me? I ensure your webhooks are strictly validated, your data flow is predictable, and your user experience (like tokenization flows and post-payment automation) is seamless.

Lets secure your apps data flow. Message me to discuss your specific integration needs.
