About

Hello World...

I'm JacTBB, a software engineer in Singapore.

I have interest in building Roblox assets & related systems. As well as the infrastructure that goes behind a capture-the-flag competition.

I enjoy participating in capture-the-flag (CTF) competitions.
These are the teams I participate with, Glitched Force, Yes But No, Singapore Students Merger.

I love self-hosting applications on Linux.
Some of the services I host include VPNs, hosting platforms (Coolify, Easypanel, Portainer, Kubernetes), monitoring dashboards, DNS, OpenWebUI, my various projects and more!

I am currently a student at a polytechnic, where I study Information Technology.

Away from my battle station, I love hanging out with friends and playing games.
