About Me

I hold a Bachelor’s degree in Cybersecurity with a concentration in Computer Science from California State University, Fullerton. My academic background combines security, systems, networking, and software development, supported by coursework in machine learning, artificial intelligence, blockchain technologies, malware analysis, networking, and web security.

My technical focus is centered on cloud infrastructure, identity, DevOps, and cybersecurity. I am particularly interested in building practical, security-aware systems and developing hands-on experience through labs, projects, and technical experimentation.

This site serves as both a technical portfolio and a learning journal. I use it to document what I study, what I build, what breaks, and what I learn from fixing it.

Web Application Project: Reel Reviews

I designed and deployed a full-stack movie review platform using the MERN stack.

Hands-on Cybersecurity Labs

I have completed practical labs across platforms such as TryHackMe, Hack The Box, OffSec Proving Grounds, INE SkillDive, and PentesterAcademy.

Experience

Information Technology Support

Chung Yin Hong Limited
2017 – 2019

Designed and maintained the company website and hosting services
Provided technical support for desktops, printers, software, and network devices
Monitored web services for uptime and performed troubleshooting and updates as needed

How I Learn

My learning style is strongly hands-on. I prefer to combine:

official documentation
guided labs
technical experiments
project-based learning
troubleshooting real issues
writing notes and technical summaries

Long-Term Direction

My long-term direction is to continue building deeper capability in:

cloud infrastructure
DevOps and platform operations
identity and access management
automation and infrastructure as code
cloud and infrastructure security
offensive security as a complementary technical skill

I aim to develop into a well-rounded technical professional who can work across infrastructure, security, and automation with a practical, engineering-focused mindset.
