At TATA Consultancy Services, I lead development and ongoing maintenance of Citi Bank’s COSMOS system for international operations in Colombia and Puerto Rico. I’ve improved modules for loans and deposits, cashier’s checks, current accounts, and payment orders.
At Experian Services Chile, I led software delivery and maintenance for Portfolio Management Systems (PMP), supporting financial institutions in the U.S. and energy-sector clients. I optimized batch and online processing, helped modernize PMP architectures through migration to AWS, and supported critical production platforms around the clock.
Earlier, at ISBAN and Banco Santander Chile, I worked on core banking platforms, including automated credit lines, current accounts, and the migration of SAFE to ALTAMIRA. I also contributed to CMM and CMMI quality certifications and provided mission-critical production support.
