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.
