• Architecting a highly available, disaster-resilient, multi-cluster secrets management platform.
• Driving Vault from PoC to enterprise-grade production, establishing standards, reliability, and scalability.
• Collaborating with Cloud Engineering, DevOps, and SRE teams on secure secret management workflows.

• Implementing Policy as Code using Sentinel to automate guardrails and access decisions.
• Engineering Vault infrastructure using Terraform with fully automated, reproducible deployments.
