About Rohit Kumar

Senior Lead Engineer at Qualcomm specializing in end-to-end display and graphics systems across Android and Linux platforms. I design, develop, and optimize the complete display pipeline - from kernel-mode drivers and DRM/KMS to Android framework components and Wayland compositors - delivering high-performance, power-efficient display solutions for embedded and IoT devices.My core expertise includes Android Display Stack (SurfaceFlinger, Display HAL, HWC, HWComposer, Gralloc) and Linux graphics stack (DRM, KMS, Wayland, Weston, GBM), with deep hands-on ownership of composition, vsync, synchronization, memory management, color processing, and performance optimization. I work closely with GPU, multimedia, BSP, and hardware teams to translate platform capabilities into robust, production-ready features.Previously at Intel, I developed Windows kernel-mode display drivers and GPU software, building strong foundations in low-level graphics architecture, driver design, and complex system debugging. Actively exploring opportunities in:Display Systems | Graphics Architecture | GPU Software | Kernel & System Software | Embedded Linux | Android Platform | IoT Display | Staff / Principal Engineer roles
