What I'm looking for

I'm looking to lead strategic technology initiatives involving digital transformation, high-availability platforms, cloud migration, DevOps, and AI adoption while aligning delivery with business goals, compliance, and operational continuity.

I've led transactional core-service operations and migrations for Mercado Pago, protecting continuity and scalability in high-traffic backend environments.

Across fintech, banking, telecommunications, and public-sector projects, I've delivered online banking, payment, core banking, and digital-product initiatives while aligning technology decisions with business goals and regulatory requirements.

I've managed multidisciplinary teams spanning development, QA, DevOps, and data, using Scrum, Kanban, SAFe, PMI, and ITIL practices to run delivery, incidents, service integration, and change.

My technical foundation includes backend architecture, distributed systems, cloud migration, databases, high availability, DevSecOps, and data and AI initiatives. I bring more than 12 years of experience building resilient technology operations for critical environments.
