• Utilized C for implementing features to the Actian Vector, and Python for testing. • Implemented system calls to the database engine to perform basic file system operations on various file system types such as NTFS, ext4, HDFS, and cloud-based. • Implemented an optimization strategy to hash tables used by the database engine for query execution, improving overall query performance by 15%. • Designed and implemented an Automated DBMS Tuning service for the Actian Vector based on system metric predictions.

• Graded weekly assignment submissions and hosted both online and in-person help sessions to support student learning. • Guided students through course topics such as sorting algorithms, data structures, time complexity analysis, and so on.

• Evaluated weekly assignment submissions, led help sessions, and aided students in solving C/C++ problems during tutorial classes. • Covered core C/C++ concepts such as language syntax, memory management, pointers, and object-oriented programming. • Developed a Python script to automate parts of the grading process, reducing evaluation time by 20%.
