About Me
I am an information security student and penetration testing software developer. I started learning programming and cyber security in 2019 in Moscow School of Programming and now improving my skills using open resources. I am currently developing several open-source projects on my platform EntySec and participating in cybersecurity conferences.
My goal is to continue educating in the direction of information security and to develop my skills non-stop.

Skills
Software Development
I can develop various software from post-exploitation frameworks in Python and advanced payloads in C and Assembly to Web platforms based on Django and Flask.
Penetration Testing
I have experience in finding flaws in different systems from IoT (Internet of Things) to more advanced ones.
iOS Security
The interest in iPhone jailbreaking lead me to the development of tweaks and payloads for iOS.
CTF & A/D Olympiads
My interest in CTF started in Moscow School of Programming where my friends and I found a ShadowLegacy team and participated in lots of olympiads. On most of them we took the first place.
Low-level Programming
I am an author of payloads which I wrote in Objective-C for macOS/iOS and in C for POSIX-based platforms and Windows. Moreover, I wrote shellcodes in Assembly for MIPS, arm, x86 and x64.
Portfolio
Below is the list of my open-source projects that I've developed and currently working on. Most of them are connected to each other, creating a digital ecosystem that can be used to conduct penetration tests, provide a convenient workspace for security research, or participate in CTFs.
