What I'm looking for

I’m eager to leverage my expertise in Kubernetes, Terraform, and Python to modernize infrastructure and enhance development environments at Devlane.

At Carsales, I architected self-hosted GitHub Actions runners on AWS EKS using Helm and Terraform, optimizing CI/CD pipelines for QA and mobile development teams.

I developed Python automations with Lambda and EventBridge to remediate AWS resource issues identified through CloudWatch metrics. I also implemented New Relic monitoring for applications and RabbitMQ services, helping reduce incident detection and resolution times.

At Carsales, I contributed to agentic AI tooling for root-cause analysis and collaborated on RDS/Aurora database migrations and engine upgrades. I also migrated a telephony platform to a nearby AWS region, reducing network expenses by 13% and latency by over 100 ms.

Previously, as Lead SRE at Aligare, I established its Terraform and CloudFormation IaC repository and helped define its CI/CD strategy and deployment standards. I also created an automated Kubernetes node-recycling service and configured observability dashboards that improved incident detection and response times by 40%.
