I am a Java backend engineer specializing in enterprise digital identity platforms, with expertise in IdP integrations, authentication flows, and service reliability. My experience ranges from modernizing legacy JBoss/Tomcat services to implementing solutions on Spring Boot, Kafka, and container infrastructure. Most recently at Innowise, I improved system throughput, implemented observability, and engineered resilient authentication bridges. I focus on fault tolerance, performance testing, and infrastructure automation, always striving for robust and scalable software. Motivated by challenging environments, my career goal is to architect secure, high-performing backend systems.

Raised system throughput by about 50% under fault conditions through timeout overhaul. Designed per-request deadline propagation to ensure fail-fast for slow requests. Introduced observability using Micrometer, Prometheus, and Grafana for metrics at multiple granularities, and presented dashboards to clients. Owned a secure auth bridge federating a Spanish payment gateway with the core IdP. Built a resilient proxy for event delivery between Azure Queue and RBA service, ensuring retry/backoff and exactly-once semantics. Refactored logging for asynchronous dispatch and dead-letter capture. Identified and resolved a race condition affecting PKI certificate tasks. Provisioned testing environments with Terraform/Ansible and modernized Jenkins CI/CD.
