PROFILE
Milan Krstic
Milan Krstic contributed to the DragonBluep/openwrt repository by developing and refining firmware and kernel support for Qualcomm-based devices, including the TCL LINKHUB HH500V. He implemented device tree configurations and firmware adjustments to enable dual-band 802.11ax 5G NR CPE compatibility, and addressed kernel scheduling issues by enabling can_sleep on GPIO expanders to resolve ringbuffer errors. Milan also enhanced bootconfig partition management and improved sysupgrade reliability through targeted shell scripting and system administration. Working primarily in C and Shell, his work demonstrated a strong grasp of embedded Linux, kernel development, and practical problem-solving for production hardware environments.
