Featured Work

Outcomes over algorithms. Here's how I've helped teams ship measurable results.

Skills & Expertise

Building outcomes, not artifacts. I focus on small, end-to-end loops—ingest → infer → evaluate → iterate—with guardrails and observability from day one.

  • Threat modeling and VAPT remediation backlogs

Tools:

ISO 27001 controls
GDPR DPIA
SIEM alerts
+1 more

Team Coaching

Rituals, standards, and feedback loops that raise velocity.

Key Outcomes:
