What I'm looking for

I'm looking to build and lead resilient, scalable backend and full-stack solutions for high-impact banking, payments, telecommunications, or government platforms, with modern Java, cloud, microservices, event-driven architecture, and strong engineering quality practices.

I've delivered Java microservices, APIs, and event-driven systems for BCP, Interbank, Culqi, SUNAT, Claro Perú, and Scotiabank. My work spans banking, digital payments, telecommunications, and government platforms where availability, security, and scalable integrations matter.

Most recently, I build and maintain financial backend services with Java 17/21, Quarkus, hexagonal architecture, Kafka, and Azure at NTTDATA for BCP. I’ve led legacy-to-microservices migrations, reduced API and batch response times by up to 40%, integrated payments with Yape, Visa, and banks, and led backend teams through production deployments, quality practices, and CI/CD automation.
