Ph.D in computer science
My Ph.D. work was a study on bugs and error propagation in Linux kernel. At that time, I used natural language processing and machine learning to extract useful information for verifying device drivers from software repositories.
Now I'm optimizing Apache Spark, MongoDB, NVMe driver with SPDK/DPDK, and other data processing systems. I am also exploring the possibility of POWER systems for high performance data processing.
