Integrate and maintain payment gateways (Stripe, Adyen, PayPal, Visa/Mastercard, etc.) and ensure PCI compliance.
Write clean, scalable, and secure code following best practices (TDD, SOLID principles, etc.).
Work closely with the QA and DevOps teams for CI/CD integration, automated testing, and deployment.
Monitor, troubleshoot, and optimize microservices performance using AWS CloudWatch, X-Ray, or similar tools.
5+ years of experience in .NET development, with at least 2+ years in .NET Core / .NET 6/7.
