Experience
Software Engineer
Jul 2024 — Present · Delhi, IN
Developed a Kernel Module for optimally storing CPU usage stats similarly to TOP command during cold boot with minimal overhead using a complex multi-threaded design while using just 4-5 MB of memory.Implemented PMU monitoring kernel module which monitors and report culprit processes that are consuming system resources.Added a feature in Vlogger module which stores logs upto 32MB of memory and implementation is purely lockless to avoid CPU overhead Applied learning based approach to dynamically alter the behaviour of kswapd and kcompactd as per the current kernel state. It reduces memory stalls by around 60% under intensive memory stress test.Implemented IRQ latency analyzer which provides interrupt details and provided a feature which allows it to change CPU deadline stuck time using user space interface.Implemented KZM (Kernel zero page Merging) which merges zero pages present in memory to avoid de-duplication.Development of KCSAN (Kernel Concurrency Sanitizer) which reports data races on linux 4.9 and 5.4Worked with vlogger kernel module which implements logger without using any locking in its implementation to reduce extra time due to locking mechanism.Integrated Ureadahead package on linux 4.9 and linux 5.4 kernels to reduce the boot time by 10-15%.Automated AVAS review website for CVE using selenium web driver.
