Works on large-scale platform modernization across AWS and Azure environments, with an emphasis on release engineering, Kubernetes adoption, observability, and production reliability for multi-environment enterprise systems.

• →Modernized Dev, QA, Sandbox, and Production AWS stacks using CloudFormation and CDK, improving deployment consistency and reducing release cycle time.
• →Migrated containerized microservices from Amazon ECS to Kubernetes EKS with Helm and Argo CD, reducing deployment lead time and enabling self-service rollouts.
• →Implemented observability with Datadog, Prometheus, and Grafana, and supported backend modernization work including .NET 8 upgrades, Lambda-based workloads, and stronger SSL/TLS enforcement.

Supported finance and backend engineering initiatives at Audible, connecting frontend and backend systems while improving service security, testing coverage, and operational reliability for internal workflows.

• →Extended finance tooling by integrating React interfaces with Java Spring Boot services using AWS SWF, SQS, and Lambda.
• →Replaced a bypass authorization mechanism with a secure OAuth 2.0 Java Spring client to close a critical security gap.
• →Implemented Selenium-based functional testing in AWS and participated in 30+ interview loops spanning coding, system design, and hiring evaluation.

Contributed to a large migration effort from on-premise infrastructure to AWS, standardizing provisioning, deployment automation, and service containerization for a multi-phase modernization program.

• →Migrated more than 15 service repositories from Angi data centers to AWS using Terraform, cutting provisioning time and reducing manual setup.
• →Containerized legacy services with Docker and standardized machine configuration through Ansible.
• →Rewrote deployment scripts from Bash to Ansible, reducing environment drift and improving incident response during the migration.

Focused on AWS cost optimization, database resilience, and the introduction of foundational SRE practices for a growing engineering organization.

• →Reduced AWS infrastructure costs by more than 25 percent through Cost Explorer analysis, Glacier archiving, and application resource optimization.
• →Introduced RDS read replicas and improved resilience patterns across AWS Elastic Beanstalk deployments.
• →Rolled out Datadog to EC2 infrastructure and established documentation, on-call rotation, and postmortem practices to strengthen reliability culture.

Worked on internal tooling and operational support for Oracle's global cloud support organization, with responsibilities spanning Java services, observability, Kubernetes operations, and SLA support.

• →Developed and maintained internal Java tooling, including Jira and Atlassian integrations used by global business units.
• →Monitored cluster services through Prometheus and Grafana dashboards while supporting SLAs through on-call rotations and ticket-driven operations.
• →Provisioned Oracle Container Engine environments for custom projects, including compliance and approval workflows.

Joined as one of the earliest engineers and helped scale the product and engineering organization during a period of rapid growth, contributing across DevOps, mobile delivery, frontend systems, and backend product development.

• →Helped scale the engineering team from 3 to 20 developers while contributing to hiring and engineering culture.
• →Led DevOps work behind a free insurance app experience launched during COVID-19, supporting more than 2,500 weekly medical video consults across Mexico.
• →Automated Android and iOS releases with Travis CI, CircleCI, and AppCenter, and built product features with React, Redux, Apollo, GraphQL, Django, and WebRTC tooling.
