JULIUS OTEGA

I’m a Cybersecurity and Cloud Security professional with 3+ years of hands-on experience securing cloud, identity, infrastructure, and enterprise environments across AWS and Microsoft Azure.

My experience spans both defensive security and cloud engineering. I’ve worked with Microsoft Sentinel, Defender for Endpoint, KQL, Tenable, threat hunting, incident response, vulnerability management, DISA STIG hardening, and security automation. On the cloud and DevSecOps side, I’ve built and secured AWS/Azure environments using Terraform, Kubernetes, Amazon EKS, Azure AKS, Docker, CI/CD pipelines, and security controls integrated throughout the delivery process.

I have hands-on experience with IAM and identity security, including AWS IAM, IRSA, Microsoft Entra ID, Azure RBAC, managed identities, Active Directory, least-privilege access, HashiCorp Vault, and Azure Key Vault. I’ve also worked on authentication monitoring, identity threat detection, SIEM investigations, and security automation using PowerShell, Python, and Bash.

Some measurable outcomes from my work include a 100% reduction in critical vulnerabilities, 90% reduction in high-severity vulnerabilities, 76% reduction in medium-severity vulnerabilities, and a 100% reduction in brute-force login attempts through security controls and remediation.

I’m particularly interested in hands-on roles involving Cloud Security, Cybersecurity, IAM, DevSecOps, Security Engineering, Cloud Infrastructure, and Security Operations. I enjoy solving complex technical problems, improving security through automation, and building secure, reliable cloud environments while continuing to grow as an individual contributor.
