Zero Trust networking
Identity-aware access, segmentation, and Zscaler ZIA, ZPA, and ZDX at enterprise scale—replacing broad network trust with explicit decisions.
- Secure access architecture
- Identity and device context
- Policy-driven connectivity
Cybersecurity + applied AI
Secure systems.
Useful AI.
Less theater.
I lead enterprise Zero Trust and security engineering programs, then bring the same rigor to applied AI: clear trust boundaries, measurable outcomes, and systems people can operate.

For more than 15 years, I have worked where identity meets infrastructure—from frontline support to enterprise security leadership in regulated financial services.
What I bring
Strategy that can make it into production.
Architecture is only valuable when teams can operate it. My work connects the control plane, the network, the telemetry, and the human experience.
Security operations
Incident response, firewalls, IDS/IPS, IAM, SIEM, endpoint security, and continuous monitoring with an operator's eye for evidence.
Applied AI research
Research into assistants and agents that support analysis and automation—with evaluation, guardrails, and human review built in.
Product engineering
Turning ideas into working web, iOS, and AWS systems; testing the seams where architecture diagrams usually stop.
Independent research
R / 01AI that earns trust.
The useful question is not “Can AI do this?” It is “How do we know when it works, when it fails, and when a person should take over?”
Secure use of AI
Threat models, data boundaries, identity, permissions, and approval points for AI-enabled workflows.
Agent reliability
Evaluation, failure analysis, observability, and feedback loops that make autonomous behavior reviewable.
Practical augmentation
Turning security expertise into repeatable workflows without removing judgment from the humans accountable for outcomes.
Professional experience
15+ years. One through-line.
From hands-on support to enterprise leadership, I have built a career around making complex technology safer, more dependable, and easier to operate.
