I use to play CTFs with OpenToAll. Other than that I did HackTheBox or Vulnhub. Also wrote loads of writeups, mostly Vulnhub machines.

Now I make rooms on TryHackMe and VMs on Vulnhub. The series that I started on Vulnhub is called djinn.

Also I am an eJPT(google that) and preparing for OSCP.

Recently I started to do bug bounty on various platforms like Hackerone, BugCrowd and intigriti.
