• Collaborated with research teams (INSTalytics, GSL) to conduct and productize research.
• Contributed to DevOps, mitigating livesite issues and conducted interviews for the Azure Data Org at Microsoft.

Software Engineering Intern

AirMettle (Mentors- Donpaul Stephens and Matt Youill)

• Worked on building a Query Optimizer for semi-structured data (JSON, NetCDF, Tensor)
• Improved the performance of querying atmospheric data provided by NOAA
• Designed novel multi-dumension shuffle operation to enable distributed execution of big-data queries that operate on tensor data

Research Intern

Microsoft Research Labs India (Mentor- Dr Bhargav Gulavani and Dr Kaushik Rajan)

• Worked in the INSTalytics team (Systems Group) on optimizing SCOPE query plans.
• Made smarter use of SSDs to perform more intelligent query optimizations in the SCOPE Engine.
• Productized the work in the SCOPE Query engine impacting ~14% of customer workloads bringing average savings of about ~10% in compute time.

Research Intern

Carnegie Mellon University (Mentor- Dr Jiyuan Zhang and Dr Franz Franchetti)

• Worked on optimizing graph algorithms using SIMD acceleration in the SPIRAL group.
• Designed a set operation based implementation using Intel Vector Instructions of the breadth first search algorithm which beat the benchmark for the breadth first search on some graphs from SNAP.
• Identified the bottleneck of the algorithm to be the SIMD implementation of small-large set operations
