About me
I am a Senior Backend Engineer with 17 years of experience building and delivering software for fintech, banking, and enterprise environments. My background is centered on Java, Spring Boot, clean architecture, and secure system design.
I have led full SDLC delivery across complex, high-impact projects, from requirements gathering and architecture to implementation, deployment, and support. I enjoy working on systems that need reliability, scalability, and strong integration with business processes.
My technical strengths include Java, Spring, Spring Boot, REST and SOAP web services, ETL, SQL optimization, AWS, Docker, CI/CD, and event-driven and microservice-based architectures. I have also worked with Flutter, Dart, Node.js, C#, JSF, JPA, Oracle, and Pentaho Data Integration.
Throughout my career, I have delivered solutions that improved operational efficiency, reduced manual work, and accelerated business outcomes. Examples include transaction automation, credit scoring systems, debt collection workflows, payments alerts, manufacturing execution systems, and banking platforms.
I have also taken on leadership responsibilities by guiding development teams, training junior engineers, coordinating with stakeholders, and ensuring technical alignment across projects. I value clear communication, code quality, and practical architecture decisions.
I hold an MBA and a Computer Science degree, and I have earned certifications in Scrum, Oracle SOA/BPM, and AWS AI. I am based in El Salvador and continue to focus on backend engineering, architecture, and technical consulting.
