Leo Prasath Arulraj


I work on Virtual Storage Performance (more broadly on Software Defined Storage) under the wonderful guidance of Prof.Andrea Arpaci-Dusseau and Prof.Remzi Arpaci-Dusseau while simultaneously spending significant time trying to explain myself the flawless magic they create every single time. They are amazing advisors and I am more than fortunate to have them as my academic parents.

Writeups


Work Experience

  • 2011-2012 : I worked on the Monitoring, Metrics, Alarming, Periodic Actions and Hadoop/Hive based large scale log processing parts of the AWS DynamoDB NOSQL database service
  • 2006-2008 : I worked for 2 years at the Amazon.com Development Center in Chennai, India with wonderful colleagues in the Digital Technology (Kindle) Team and learned a lot on Product development, testing, deployment, people skills. [ sometimes, the hard way. ;) ]

Internship Experience

Teaching Experience

  • I was a Lab Teaching Assistant for an Introductory Programming in Java course for a semester during which I monitored undergraduate students during lab sessions, held office hours to help students learn better and creating lab assignments along with other Teaching Assistants. It was a fun and rewarding experience to interact with new undergraduate students from various departments who are mostly just getting introduced to Computer Science / Programming.
