Infrastructure & Security Highlights
- TrueNAS + Zero Trust deployment Designed and deployed a TrueNAS SCALE storage platform secured with an NGINX reverse proxy and Cloudflare Zero Trust tunnels, enabling authenticated remote access to NAS services while masking internal network exposure and enforcing identity-based access controls.
- Zero Trust architecture implementation Implemented a layered Zero Trust access model using Cloudflare WARP, device posture checks, and DNS-level filtering to protect internal and externally exposed services across the homelab environment.
- Enterprise network transition support Supported production network infrastructure upgrades during fulfillment-center environment transitions, contributing to hardware lifecycle deployment and service continuity with zero operational downtime.
- Cybersecurity CTF and incident response work Completed Capture-the-Flag cybersecurity exercises and developed structured incident response reports analyzing attack vectors, detection methods, and mitigation strategies as part of undergraduate cybersecurity training.
