I'm a Senior Security Engineer with a real passion to software development and security. I had a chance to work both as a Python Developer and Offensive Security Consultant performing penetration tests of web and mobile applications for external clients. Currently, I'm working as a Security Engineer in Application Security Team.

My professional carreer started with Python and this language stayed with me over last few years. I'm developing various tools with Python and some of them are open-sourced and available on my GitHub profile.

On Medium I'm writing about security, especially in context of SDLC, DevSecOps and API but I'm not limited to those topics! My articles can be also found at devsec-blog.com.
