Home lab
A Raspberry Pi that I run and maintain myself.
- Zero-trust remote access: Tailscale VPN.
- Containers: a Docker stack running Nextcloud and a MariaDB database.
- Segmentation and firewall rules: network segmentation with firewall rules between services.
- Malware analysis isolation: container isolation for examining suspicious files.
- Data pipeline: a Python and Streamlit app that reads from a live MariaDB backend.
Security work
- Access control: redesigned multi-factor authentication for a hospital HR system serving more than 10,000 employees under HIPAA. Unauthorized access fell 30%, and two audit cycles closed with zero findings.
- Security operations: kept incident logs (100+ a quarter), spotted recurring access patterns and flagged them to management, and supported the onboarding of new staff on security procedures.
