At 7Net (Credicard), I architected and contributed to a Gateway Backend in NestJS that serves three web platforms and a mobile ecosystem. I also developed payment capabilities including SoftPOS, Mastercard card tokenization, QR and P2P payments, and digital KYC onboarding.
At 7Net (Banco de Venezuela), I built backend systems for institutional key management, internal request workflows, approvals, and vulnerability management. I also built a Java 21 and Spring Boot card endpoint using an IBM iSeries stored procedure, and I'm developing an inventory, sales, and debt management web app.
