AI cloud security architect at SAP NS2 securing Azure and AWS AI platforms with threat modeling, guardrails, and production observability.

United States
Message

At SAP National Security Services (SAP NS2), I lead architecture and delivery for secure Azure and AWS platforms, including AI-enabled services built with Azure AI Foundry, Azure OpenAI, Amazon Bedrock, and SageMaker.

I implement AI security guardrails for prompt injection, unsafe tool use, data exfiltration, model access, and sensitive-data protection. I also develop evaluation, logging, and incident-response patterns for AI workloads.

At SAP NS2, I established production observability with Azure Monitor, Log Analytics, Application Insights, and Splunk, improving detection-to-triage time by approximately 45% for recurring platform events.

Earlier, at Tata Consultancy Services and on its Boston Scientific and Pfizer engagements, I delivered secure Azure and AWS platform engineering. On the Caterpillar engagement, I designed and operated Azure services for containerized workloads; at Progress Computer Training Center, I developed and supported Python web applications and SQL/Azure database services.
