Cencosud

I set technical guidelines for multiple development teams, leading the implementation of scalable, event-driven, decoupled solutions with AWS as the primary cloud provider. I design and build the infrastructure to deploy AI agents on AWS Bedrock —AgentCore Runtime, Gateway, Memory, Policy Engine, and Guardrails— using Terraform (HashiCorp) as the infrastructure-as-code standard. I establish AWS security policy standards, provide technical support across business lines, prepare migrations, and estimate effort for new initiatives.

IBM Chile - Banco Estado

I led the end-to-end development of Casaverso.cl from the ground up, the critical transactional digital platform for a leading bank in Chile. I designed and established its foundational architecture in the cloud (AWS/Kubernetes), implementing microservices with Nest.js, frontend with Angular, and atomic libraries of reusable components that ensured decoupled, maintainable development aligned with best practices. I directed agile and multidisciplinary work cells, aligning business objectives with strategic technical decisions, and managing the complete product cycle — from conception and architecture design to production operations — ensuring a robust, scalable, and secure platform.
