About Luis E. Ramirez

AppSec for the AI-native stack.

I work where application security, AI security governance, and agentic engineering meet. My focus is helping teams turn ambiguous AI/product risk into clear architecture, bounded automation, reusable evidence, and controls that engineers can actually operate.

Working thesis

Turn security drag into infrastructure.

I am strongest in environments where the security function is still being formed: the controls are not all mapped, the AI workflows are still fluid, and the organization needs someone who can define what good looks like without slowing engineering to a crawl.

Bounded automation

I combine manual security judgment with automation that stays bounded, reviewable, and evidence-backed. Repeated work such as questionnaires, vulnerability routing, AI control mapping, and evidence collection should become a reusable system with human accountability at the final decision point.

High-trust product teams

I fit teams building high-trust software: SaaS platforms, AI-enabled workflows, regulated products, and organizations that need practical security leadership before they have a large formal security department.
