Practical, recruiter-ready penetration testing writeups and sanitized PoC. All published work is performed in controlled lab environments or on retired training machines (see Legal & Ethics).
- Focus: Web, Linux containers, Windows privilege escalation — short, sanitized writeups aimed at hiring managers.
- Featured writeups:
- Planning — Grafana RCE → container → cron → root. (Lab)
- Devel — Windows FTP / webshell → PrivEsc. (Lab)
- Toolbox — SQLi → container pivot → host. (Lab)

🚧 Under Construction 🚧
Like any good exploit chain, this site is being built step-by-step. Stay tuned.
- Scroll-triggered animations
- Responsive layout for all devices
- Semantic HTML and clean CSS
- Custom branding and favicon
- HTML5, CSS3, JavaScript
- Jekyll + GitHub Pages
This portfolio was designed from scratch with a focus on clarity, creativity, and technical polish. I iteratively refined the layout, animations to ensure smooth UX across devices. Every element — from the favicon to the scroll-triggered fade-ins — reflects my attention to detail and passion for visual storytelling.
I used semantic HTML and modular CSS to keep the codebase clean and scalable. The site is deployed via GitHub Pages using Jekyll, allowing for easy updates and version control.

I'm Jing Xian — a full-stack developer turned cybersecurity explorer. I approach both technical and interpersonal challenges with emotional intelligence, strategic reflection, and a touch of creative flair. This portfolio is more than a showcase; it's a space where curiosity meets code, and where I experiment with visual storytelling, subtle animations, and authentic branding.
Whether I'm decoding vulnerabilities or refining UX, I believe in thoughtful design, iterative growth, and building genuine connections — online and off.
All public writeups describe exploitation performed in controlled labs or on retired machines where disclosure is permitted. PoC included here is sanitized — no live credentials or destructive exploits.
