About Me

Currently pursuing an MS in Computer Science at the University of Illinois Chicago, with a focus on advanced data engineering, distributed systems, and big data technologies. I hold a Bachelor’s degree in Computer Science from R.V. College of Engineering, Bangalore, and am an AWS Certified Data Engineer – Associate.

Previously, I worked as a Senior Software Engineer at Fivetran, where I specialized in building efficient ETL pipelines and high-performance database connectors. My contributions include optimizing the BigQuery data writer to significantly reduce customer costs and designing fast, reliable connectors for DynamoDB and MongoDB. I also led the development of the widely adopted Isolated Endpoint Sync (IES) framework and mentored interns in 2023.

Passionate about building scalable, reliable, and innovative data solutions, I enjoy solving complex engineering problems that help organizations make data-driven decisions. I'm actively seeking opportunities to contribute to impactful backend and data engineering teams.
