Hi, I’m Phichit Sapnan - most people call me Wang, and online I go by Synapse.
I’m a Computer Science student from Thailand working at the intersection of offensive security and agentic AI systems. By day I break web apps, networks, and Active Directory in CTFs and lab environments; by night I’m engineering multi-agent AI ecosystems and writing down everything I learn along the way.
“Breaking systems to learn, writing code and context to remember.”
This site is the casual side of my portfolio - a public lab notebook of challenges I’ve solved, competitions I’ve joined, tools I’ve built, and notes from a journey that bounces between red team work and AI research.
Focus Areas
Offensive Security
- Web application security (OWASP Top 10, business logic flaws, auth bypasses)
- Network & internal penetration testing
- Active Directory attacks & defense (Kerberos, ACL abuse, lateral movement)
- Digital forensics & incident response
AI & Automation
- Multi-agent AI ecosystems and agent federation
- LLM-powered tooling for security workflows
- Building autonomous agents that actually ship
CTF
- Web, crypto, forensics, reversing
- Active player, learning by competing
Currently
- Studying Computer Science
- Sharpening pentest skills against AD labs and web targets
- Building an agentic federation framework
- Writing up everything worth remembering
