Auckland, New Zealand Open to junior infrastructure & network roles NZ open work visa

I’m an AUT Networks and Cybersecurity graduate looking for hands-on infrastructure and network operations work in Auckland. Most recently I was an IT Engineer in Beijing, where the job ran from endpoint support to administering DLP and zero-trust platforms, upgrading a firewall over a serial console and handling a server-room cooling failure. At home I run a NAS-based lab I’ve been building on for over a decade. I like the problems that start as “it just stopped working” and end in a packet capture or an event log.

Experience

IT Engineer — Hanshow Technology Co., Ltd.

Jan 2026 – Jul 2026

Beijing, China

  • Administered the IP-guard endpoint security / DLP platform across a mixed Windows, macOS and Ubuntu fleet; deployed and troubleshot zero-trust endpoint clients.
  • Upgraded a blade-server next-generation firewall via serial console.
  • Handled an emergency server-room cooling failure, avoiding equipment overheating and downtime.
  • Root-caused a Linux workstation video-signal drop to an MDM agent contending for DRM master.
  • Resolved Microsoft 365 authentication failures, Windows domain trust breakdowns and BitLocker recovery issues.
  • Worked with endpoint-security and zero-trust platform vendors on fault investigation and escalations.

Home Lab & Projects

INFRASTRUCTURE

Self-hosted service stack

QNAP QuTS hero on ZFS running Docker workloads behind a hardened reverse proxy, with automated container update monitoring and per-service access rules.

NETWORKING

Home network & remote access

A virtualised router appliance (iStoreOS) running on the NAS as a bypass gateway, with external access through a TLS reverse proxy. Assessed CGNAT limits for remote access and evaluated tunnelled and mesh-VPN alternatives to exposing ports.

PERFORMANCE

Media transcoding bottleneck

Traced stuttering 4K60 playback past the obvious server-side suspects to a client codec level incompatibility that was forcing a 4.5 fps server transcode — measured with VAAPI benchmarks against disk and RAM-disk sources.

FORENSICS

Anomalous egress investigation

Investigated a 209 GB upload spike using Windows SRUM data and proxy topology analysis to separate a compromised credential from a local device exfiltrating data.

ACADEMIC PROJECT · AUT

Windows domain migration

Five-person team project: replaced a peer-to-peer network with a Windows Server 2016 Active Directory domain — DHCP scopes, DNS, role-based groups, roaming profiles, Group Policy firewall rules and Windows Server Backup to a remote share. Co-authored the 20-page operating manual.

PERSONAL PROJECT · C++ · OPEN SOURCE

QuadDeck — multi-video player

A native Windows player for up to five videos with synchronised or independent playback, D3D11 hardware decoding via FFmpeg, ASS subtitles, Emby library browsing and read-ahead caching for NAS sources. I designed the features and directed AI coding assistants (Codex, Claude Code), then tested it against my own NAS and Emby server, fixed the bugs that turned up and packaged the release. GPL-3.0.
