I speak about AWS in practice: platform engineering, DevSecOps and AI agents operating cloud infrastructure, always with live demos and real failures instead of perfect slides. I’m happy to join AWS User Groups, Community Days, meetups, universities and online events.

Talk topics
Giving AI Agents Prod Access Without Getting Fired
Kiro, Amazon Q and MCP servers can now run commands against your AWS accounts. A threat model for agents with cloud credentials, the IAM guardrails that contain them and how to detect what they did. Live demo: an agent tries to break the account and the guardrails hold.
DevSecOps vs. Chaos: AI in the Real World
What happens when an AI assistant meets broken pipelines, misconfigured settings and real security risks. What it gets right, what it gets wrong and where it should not be trusted.
Native AWS Detection & Response
CloudTrail, GuardDuty, Security Hub, EventBridge and Lambda wired into a response pipeline that actually acts on findings, and what it costs to run.
AWS: First Steps in the Cloud
An introduction to cloud computing and AWS for students and career changers: core services, pricing model, basic security and how to keep learning.
Formats: talks from 20 to 45 minutes, in person or online.
