At Indra / Minsait, I created and optimized PL/SQL procedures and SQL queries for critical financial processes. I cut mass-report execution time by 30% through PL/SQL rewrites, indexes, and optimizer hints.
I also designed and implemented ETL pipelines connecting transactional systems with analytics platforms. As a database technical lead, I reviewed three teammates’ PL/SQL development and helped new team members apply coding and tuning standards.
At Banco Nacional del Ejército (Banjército), I developed and maintained PL/SQL and Sencha Framework applications connected to Oracle databases and ColdFusion servers. I optimized queries and procedures for banking operations and automated administrative tasks with PL/SQL and shell scripts.
At Grupo Salinas, I analyzed and optimized functions and procedures, translating business rules into production-ready development. My work also includes Oracle performance tuning, execution-plan analysis, ETL optimization, and Oracle database administration.
