I have direct professional involvement with IT security since 2003, when I had professional IT security training in the USA and Canada. Since then, I have paid special attention to secure programming practices and caveats.
In the last decade, I have had (through official contracts) very strong involvement with payment systems, authentication, authorization, session management, secure API design, and related aspects.
Currently, I strive to increase my software development and security knowledge(please see my detailed CV on the Contact page).
