Gabriel Robles

Security Automation Engineer | DevSecOps

Engineer specializing in defense automation and critical infrastructure protection. I transform manual security operations into efficient code (Python) to orchestrate vulnerability detection and remediation in Cloud and Banking environments.

Tech Stack

My professional evolution combines a solid foundation in Software Development with Cybersecurity Engineering. Unlike a traditional analyst, I have the ability to write code to integrate tools, automate workflows, and secure infrastructure from the cloud to the container.

My core engineering toolset:

🛡️ Security Automation

  • Python (Boto3, Requests, Pandas)
  • Qualys (VMDR & API)
  • Kenna Security (Risk Scoring)
  • Splunk (SIEM & Logging)
  • Bash Scripting

☁️ Cloud & DevOps

  • AWS (IAM, EC2, S3, Security Hub)
  • Docker & Kubernetes Security
  • Linux Hardening
  • CI/CD Integration
  • Git & Version Control
