What I Provide
I handle the full integration lifecycle for payment gateways used in Serbia and the region. Whether you need WSPay for Croatian-Serbian cross-border payments, CorvusPay for card processing, or Raiffeisen's e-commerce gateway — I take your project from initial API documentation review through to production deployment and PCI compliance verification.
My focus is on reducing the time between signing your payment provider contract and processing your first live transaction. Most integrations are completed within 2–4 weeks, including test environment setup, error handling, and reconciliation logic.
How Integration Works
Assessment & Provider Selection
I review your business model, transaction volumes, and target markets to recommend the right payment provider. If you already have a contract, I audit the API documentation and identify integration requirements.
Technical Integration
I implement the payment flow end-to-end: checkout initiation, redirect handling, callback processing, transaction status verification, and error recovery. All code follows PCI DSS best practices.
Testing & Go-Live
Comprehensive testing in the provider's sandbox environment, followed by production deployment. I verify successful transactions, failed payment handling, refund flows, and reconciliation with your accounting system.
