Message

At Indra, I led the technical integration of BancoEstado's payment gateway and coordinated with banking, architecture, DevOps, and cybersecurity teams on secure production releases. I developed Java REST APIs and middleware supporting multi-bank payment processing, along with Spring Batch workflows for settlement files and financial reconciliation.

In my 2026 academic project, Banking Backend Modernization, I developed a four-microservice banking architecture with Spring Boot and Spring Cloud, adding OAuth2/JWT security, resilience patterns, and asynchronous processing with Apache Kafka on AWS EC2. I also developed Angular interfaces for payment workflows at Indra and contributed to responsive web interfaces and a UX/UI redesign at Soasin.
