I am Ziyahan from Turkey/Istanbul. I am working in a company as QA Tester, Security Researcher. I have developed web application since 2006, and I have been working as a professional developer since 2008. To date I have been working various company from different industries, for instances media, retail, construction, HR, etc. I consider myself as a security enthuisastic. I like to test open source applications against to latest web flaws and report them to vendors/their community.
Addition to above, I am an Esperantist who believes that people should have a common language that does not belong to any nation. I think Esperanto can solve this problem. In future I want to translate OWASP articles to Esperanto and Turkish.
