I have been in the IT industry for many years, after I met the internet in 1998 and started to be interested in software, I had experience on corporate solutions first as a hobby. I have been working as a software developer since 2011 at Talya Bilişim company, which currently produces solutions for the tourism sector. Corporate companies allow us to produce solutions to very large and various problems and change our perspective.On the other hand, since I was on the hotspot / firewall side, I continued my interest in cyber security with Cyber ​​Struggle, Akademik Bilişim (new name Mustafa Akgül Free Software Camp) and many more seminars/trainings.I volunteered in various projects to support free software, I used it, I gave training. I have been a Linux user for many years, at the same time I developed projects on FreeBSD, I supported the development of various tools and package preparation in the Milis Linux developer team. I rebuilt Komutan Linux, which I built on Debian, on Milis v1.For the last few years, I have been giving Blockchain 101 training at Mustafa Akgül Free Software Camp.I solve my own needs, I read a lot of documents. I am one of those who think that I share my knowledge and that I learn as I share.On the software side, I have developed and continue to develop various projects with PHP, Pure JavaScript, Golang and Bash.If I do not know enough to explain a subject, I believe that I have not learned. For this reason, there are many subjects that I cannot write here but think I know, but I cannot claim to know because I am not at the level to tell.The most important trainings I have received are available in my profile. The technologies that I have an idea about and that I use somewhere are also available in the keywords/abilities.
