PROFILE
Carlo Szelinsky
Developed and integrated advanced hardware support and management features for OpenWrt in the DragonBluep and namiltd repositories, focusing on network switch platforms. Delivered kernel-level enhancements such as PoE subsystem backports, Realtek MDIO PSE support, and watchdog drivers for external management MCUs, using C and device tree source (DTS) for robust device integration. Expanded hardware compatibility by adding support for Hasivo switches, implementing I2C-based presence detection for SFP modules, and enabling sensor monitoring and fan control. Demonstrated depth in Linux kernel development, embedded systems, and driver programming, emphasizing maintainability, upstream readiness, and improved reliability across diverse hardware environments.
