JOAO COSTA
Systems, Platform & Site Reliability Engineering
$ systemctl status joao.service
I started deep in endpoint engineering and macOS security, then kept following the interesting problems: self-healing compliance, data pipelines, infrastructure automation and reliability.
That path took me from Data Security → Data Engineering → Platform / SRE, where I now work on config-driven AWS automation, event-driven telemetry and infrastructure as code.
$ cat current_focus.yml
platform:
AWS Lambda, Step Functions, Terraform, GitHub Actions, Python and config-driven workflows.
roots:
Jamf-certified macOS engineering, endpoint security and self-healing compliance at enterprise scale.
$ cat certifications.json
