Informazioni su questo servizio
Hi, I'm a backend developer with 4+ years of experience including building payment and financial systems in the banking and insurance industry.
I help businesses connect their backend to the services they depend on: payment gateways, third-party APIs, and external systems securely and reliably.
What I can integrate:
- Payment gateways (Stripe, PayPal, and others)
- Third-party REST APIs into your Spring Boot backend
- Webhooks & event handling (payment status, callbacks)
- Secure token / API key management
- Data sync between your system and external services
Why me:
- Real experience with financial & payment systems I take security and correctness seriously
- Proper error handling for failed payments, retries, and edge cases
- Clean, documented, maintainable integration
Payment and API work needs to be done right, not just "working." Message me with what you need to integrate, and I'll advise the best approach before you order.

How do you handle security and my sensitive payment data?
Security is a priority. I never store card data directly — payment details are handled by the gateway (Stripe/PayPal) following their secure standards. API keys and credentials are kept safe and never hard-coded or shared. Coming from a banking/insurance background, I treat security and data handlin
