Software engineer on the MySQL HeatWave:
Designed and developed a consistent hashing that maps data partitions to nodes in the HeatWave cluster
Designed and developed elastic resize for the HeatWave cluster, allowing the cluster to resize (add or remove compute nodes) while experiencing no downtime
Designed and developed new features that enhanced HeatWave's query execution throughput, leveraging techniques like dynamic thread-level parallelism to increase compute utilization.
Developed support for many MySQL functions on the HeatWave cluster.
Contributed to testing suites, debugging, and maintenance of the HeatWave code

Investigated use-cases of Heterogeneous Memory in GPUs:
Investigated Heterogeneous Memory architectures that could provide both high memory capacity (through NVM) and high memory bandwidth (through HBM) for Deep Neural Network training on GPUs.
Proposed runtime extensions to support and manage data transfers between NVM and HBM.
Tested and evaluated our implementations using hipCaffe (a HIP port of Caffe) for various DNNs (CaffeNet, NiN, SqueezeNet, GoogleNet, ResNet, VGG).
