What I'm looking for

I'm looking to build and operate reliable cloud infrastructure, automate delivery and provisioning, and solve production reliability challenges in a collaborative, process-oriented team.

I administer an AWS-hosted Docker Swarm production environment supporting APIs, WebSockets, and static services across 8 nodes and 15 applications.

As a freelance DevOps Engineer, I've built Jenkins CI/CD pipelines, automated infrastructure with Terraform and Ansible, migrated hosts to Amazon Linux 2023, and maintained Gitea backups to Amazon S3. I've also resolved Socket.io scaling failures with Redis, eliminated duplicate scheduled jobs through BullMQ, and fixed a payment-processing race condition using atomic database status transitions.

My 10 years at Unisys Brasil in service desk operations gave me a strong foundation in troubleshooting, incident response, escalation, and clear communication with technical and non-technical users.
