Focus: AI Platform, Azure Landing Zone, and AI agents.

As Principal DevSecOps Engineer, I own the design and delivery of the AI Platform and Azure foundation that internal teams use to build and run AI agents and automation. I work across platform engineering, security, and governance so the company can scale AI workloads safely and efficiently.

AI Platform

• Building and evolving the AI Platform to support scalable, secure AI workloads and internal AI agents.
• Defining platform capabilities, APIs, and standards so teams can onboard and run models and agents with minimal friction.
• Implementing MLOps practices (pipeline, deployment, monitoring) so AI workloads are reliable and observable.

Azure Landing Zone

• Designing and implementing the Azure Landing Zone (multi-subscription, governance, compliance) that the AI Platform and other services run on.
• Establishing security baselines, policies, and guardrails so all workloads meet company and regulatory standards.
• Automating provisioning and configuration (e.g. Terraform/Bicep) so new environments are consistent and repeatable.

AI Agents & Automation

• Developing and deploying AI agents and automation on the platform to streamline operations and enable self-service for engineering and product teams.
• Integrating agents with existing systems and data sources so they deliver measurable impact (e.g. support, ops, or internal tooling).

Leadership & Collaboration

• Driving technical decisions and standards for DevSecOps, cloud, and AI infrastructure across the organization.
• Collaborating with product, engineering, and security to align platform roadmap with business goals and risk posture.
