Hi, I’m Nick.

I am a Networking & Infrastructure Specialist with a core foundation in Computer Networking, actively developing expertise at the intersection of Cybersecurity, Artificial Intelligence (AI), and Electronics. My focus is on bridging physical hardware deployments, secure network architectures, and intelligent automation.

I am currently completing my Diploma in Computer Networking at University College TATI (UC TATI), and I recently finished my industrial attachment at Jabatan Perkhidmatan Teknologi Maklumat (JPTM). There, I supported enterprise-grade network operations, from deploying production-ready LAMP stacks on bare-metal Dell PowerEdge servers to executing core switch migrations across campus facilities.

My approach to technology is multidisciplinary. I apply sound networking principles alongside proactive security verification methodologies to design, audit, and harden resilient systems. My passion for electronics drives me to analyze and engineer at the physical hardware layer, from configuring custom router firmware to examining modem chipset architectures. I also leverage AI tooling and locally hosted models to streamline infrastructure workflows and strengthen system analysis. Within my homelab, I rely on open-source solutions to replicate real-world enterprise scenarios in controlled, isolated environments.

Beyond formal coursework, I regularly evaluate network policies, orchestrate virtualized environments, and assess emerging open-source tooling, continuously refining my homelab architecture to remain current with evolving security trends.

Technical Snapshot:

  • Networking & Systems: VLAN Segmentation, Subnetting, Core Switch Migration (Ruijie, H3C, Cisco), Ubuntu Server, LAMP Stack
  • Cybersecurity (Purple Team Approach): Enterprise Firewalls & Hardening (Fortinet, UFW), Proactive Security Verification & Network Traffic Auditing (Responder, Bettercap, used in authorized lab environments to identify and remediate protocol-level weaknesses), Digital Forensics & Incident Analysis (Wireshark, REMnux, Flare VM)
  • Hardware & Electronics: Bare-Metal Provisioning, Custom Router Firmware (OpenWrt), IoT & Network Hardware
  • Virtualization, Containers & AI: Proxmox, VMware, Docker, Kubernetes (K8s), Local LLMs (Ollama)

I am currently expanding my homelab environment and documenting my technical journey, continuously refining my infrastructure and security methodology in preparation for enterprise environments.
