Summary
👤
Senior🎓
Top SchoolUladzislau Rezki is an experienced embedded software engineer with 11 years working on Linux-based systems, currently optimizing power and scheduler behavior for big.LITTLE Qualcomm SoCs on Sony Mobile’s Global Core Team. He has deep kernel and driver expertise—particularly in scheduler tuning, power management, and device drivers—and has contributed to the Linux kernel upstream work on RCU and memory reclaim, showing strong low-level concurrency skills. His background includes designing charging and fuel-gauge algorithms, crafting user-space tools for battery subsystems, and leading Unix/Linux teams earlier in his career. Based in Kalmar County, Sweden, he combines practical embedded systems delivery with proactive customer communication and a track record of shipping stability and performance improvements for mobile platforms. An unusual strength is his blend of power-engineering education and hands-on kernel internals, which informs pragmatic optimizations across both hardware and software.
