What I'm Building

Source-linked security patterns and consulting services for AI systems

TopFlow

Govern and build secure AI

Inspect a working OSV vulnerability scanner and the Untrusted Reasoning Worker pattern: source-backed findings, constrained model output, and explicit security boundaries.

  • •OSV findings remain the source of truth
  • •URW validates selected IDs against actual findings
  • •Cached demo results are not live scans
  • •Deterministic reports or optional BYOK reasoning
  • •Read the implementation and its limitations

Consulting & Advisory

AI security architecture & compliance

Help teams build secure AI systems from the ground up.

  • •AI security architecture reviews
  • •Compliance automation (GDPR, ISO 21434, SOC 2, HIPAA)
  • •Threat modeling & security assessment
  • •Product security advising
  • •Team workshops & training

About Me

Security-First AI Development

I build secure AI systems. As a former CISO, I've seen too many companies rush AI adoption without considering security implications.

That's why I created TopFlow—a platform demonstrating security-first AI patterns. It's not just code; it's a reference architecture for building AI systems with security baked in.

Today, I work with security teams and enterprises helping them navigate AI safely. Whether it's architecture reviews, compliance automation, or team workshops, I focus on making secure AI the default, not the exception.
