I am Luka Gejak, a 16 years old systems programmer and Linux Kernel Developer (luka.gejak@linux.dev). My core focus is on low-level system architecture, networking subsystems, and driver development.
My expertise includes:
- Linux Kernel Development: Actively contributing patches and improvements to the
rtw88subsystem, as well as reviewing and contributing to various linux related projects. - Driver Porting: Developing modern
mac80211-based ports for legacy drivers. Most notably, ported thertl8723bsdriver to the modernrtw88wireless framework to replace the legacy staging driver. - Android Custom Kernels: Building and optimizing custom kernels, such as my 4.19.x kernel port for the Samsung Exynos990 series, specifically optimized for Kali NetHunter, which is now upstreamed to official Kali Nethunter repository. As well as advanced root methods that use various kernel vulnerabilities to achieve root.
- Systems Engineering: Building high-performance, terminal-based system utilities and engaging in hardware-level security research.
