About

As a Senior Software Engineer at Qualcomm, I leverage my expertise in Linux Kernel and CPU scaling to develop innovative solutions that enhance system performance and power efficiency. With over 4 years of experience in the field, I have contributed to multiple projects that involve algorithm development, debugging, and testing. In my current role, I work closely with the Linux Kernel team to design and implement algorithms for scaling CPU frequency based on measured CPU utilization and performance. I also collaborate with other engineers to mitigate wastage of highly stalled CPUs by boosting memory frequency. Additionally, I have developed a circular buffer in kernel side to collect and transfer data efficiently. Prior to this, I interned at Qualcomm as an Interim Engineering Intern, where I designed and developed a smoke test suite for automatic validation of algorithms in CPU utilization. I hold a Master of Technology in Computer Science from Indraprastha Institute of Information Technology, Delhi, and a Bachelor of Technology in Computer Science from JSS Academy of Technical Education, Noida. I am passionate about learning new technologies and applying them to real-world problems.

As Part of Linux Kernel team working on algorithms for scaling of cpu frequency based on measured CPU utilization and performance, checking if all the pmu counters in the CPU is working properly if not then debug.
Also worked on a project to mitigate wastage of highly stalled CPUs cycle provided a solution to boost memory frequency in such a way that the stalls will reduce and benefit power at the same time. Tried ML model like decision tree to find the importance of feature present in the ftrace which helped removing some of the parameters.
Designed and developed a circular buffer in kernel side to collect the data and transfer it after reading the registers in lower sampling period considering the hw timer limits to user space keeping synchronization problem in mind.
Developed many script to automate process of manual work, mentored an intern to work on a Javascript project to parse ftrace data and plot graphs according to the user’s requirement, also POCs in bring up of two chip-sets.
