I am @unixfreaxjp and this is the front-end of my working space in the GitHub.
I am a security engineer, a cyber threat analyst and RE in IR field of cyber incident management. This simple page is explaining my activity in security field for supporting to community, a start of many links for many works I’ve involved. For coding, I am a practical UNIX related coder, I coded in some languages without flavors and I don’t like to do specific indentation. My code environtment is only the shells, mostly on the VT100-base.
I do programming in: Perl, Shell scripts, C, Python, Assembler or a bit of Ruby, with some web programming like: PHP, Java(+/-JavaScript), and also some VB/PowerShell etc. Currently I’m on LUA, Cython and Go for DFIR/RE purpose.
