what matters.
Digital possibilities need trust. I help you understand risks and strengthen the security of your applications, cloud and AI.
Where I can help
Security with substance.
From a single permission to the way your systems work together.
Cloud & AI
New possibilities, clear boundaries. Together, we examine identities, permissions and data flows across cloud and AI integrations.

Operations & resilience
Security needs to work every day. Useful logs, clear responsibilities and tested procedures help your team stay ready to act.

Independent security research
Curious about the details.
Responsible with the findings.
Bug bounty and open-source analysis are part of my independent security research. I focus on access control, tenant isolation and the points where systems trust each other.
I work within agreed boundaries, document findings so they can be understood and reproduced, and disclose them responsibly to the relevant teams.
