What I'm looking for

I’m looking for a role where I can drive operational excellence on AWS—using IaC, CI/CD, and strong security—to improve reliability, reduce costs with FinOps, and respond fast to incidents while continuously strengthening observability and the Well-Architected Framework.

I’m a Cloud Engineer with 2+ years of hands-on experience designing, deploying, and operating AWS infrastructure in high-availability production environments for the financial sector. I focus on operational excellence, reliability engineering, and continuous improvement aligned with the AWS Well-Architected Framework.

At LibelulaSoft CIA. LTDA., I deploy, manage, and support AWS infrastructure (EC2, S3, RDS, IAM, VPC, ALB/ELB) in 15+ production accounts. I’ve delivered 100% reduction in infrastructure provisioning time through Infrastructure as Code automation (Terraform + AWS CDK/CloudFormation), and achieved 10–20% monthly cloud cost savings via FinOps (Savings Plans, rightsizing, and resource cleanup).

I lead incident response for P1/P2 production outages (Level 3 support) while maintaining SLA compliance for 15+ financial and insurance clients. I’ve also implemented end-to-end observability (CloudWatch alarms, EventBridge rules, and automated notifications), designed scalable microservices on ECS Fargate, and enforced cloud security controls (IAM policies, AWS WAF, GuardDuty, KMS, and Secrets Manager) with reusable IaC modules and runbooks.
