Work experience

Android engineer

from 10.2022 to now (3 years 7 months)
Samsung R&D Institute Ukraine, Київ (IT)

My main experience is focused on designing and developing system tools for Android security validation according to MDFPP (Mobile Device Fundamentals Protection Profile) requirements. This specifically includes TLS/HTTPS communications, Key Storage (RSA, EC, AES), Crypto API and X.509 certificate validation, access control and app privilege levels, and system event auditing.
Working on this project required me to work deeply with AOSP (OneUI) source code, reverse-engineer some system services, and implement non-standard ways of interacting with Android at the system level. To make the application flexible and stable, our team developed a custom engine based on Kotlin Coroutines, and I made a significant contribution to it. Within this project, I was also responsible for UI/UX implementation.
