Embed security and compliance into pipelines (DevSecOps), including:
- Policy as code and guardrails.
- Secrets management and identity-based access.
- Automated security validation and compliance checks.
Promote automation first, least privilege, and zero trust principles across cloud operations.
Enable development teams with secure deployment patterns and standardized templates.

Security, Governance & Compliance:

Implement and maintain Azure security controls and platform protections.
Enforce governance using Azure Policy, management groups, RBAC, and tagging standards.
Partner with security, risk, and compliance teams on:
- Risk assessments and threat modeling.
- Audit readiness and control validation.
- Security incident response and remediation.
Ensure cloud environments meet internal security standards and regulatory obligations.

Optimization, Reliability & Continuous Improvement:

Optimize Azure environments for cost, performance, reliability, and security posture.
Improve observability and detection using Azure Monitor, Log Analytics, and alerting.
Contribute to platform roadmaps, technical documentation, and operational runbooks.
Act as a trusted technical advisor and mentor to infrastructure and application teams.

About you

- Azure Solutions Architect Expert.
- Azure Administrator Associate.
