RESEARCH

Ovid: A Software-Defined Distributed Systems Framework

2015 - Present
Designed and built a new framework for building software-defined distributed systems. The design includes a theoretical model of such a framework and an implementation that is able to transform existing large-scale systems automatically.

Chain Replication

2015 - Present
Reworked the chain replication protocol to support reconfigurations and different consistency guarantees. Currently implementing a complete chain replication library.

Paxos Made Moderately Complex

2013 - 2015
Clarified the Paxos consensus protocol using easy to understand invariants for systems programming, along with a correct and reconfigurable open source implementation.

Scalar & ScalarUp

2008 - 2009
Worked on a scalable and reactive data replication framework, SCALAR. Later, enhanced the proposed framework to take data updates into consideration. The study employed extensive simulations on Scalable Wireless Ad hoc Network Simulator (SWANS).

WORK EXPERIENCE

• Research Intern at Microsoft Research Silicon Valley (Distributed Systems Lab) May - Aug 2013
Designed and implemented an infrastructure service for building modular storage systems in a cloud environment. The service creates the most optimal, matching storage system to support desired data size, access frequency, and read or update frequency using pluggable modules.
• Software Engineering Intern at Google, Inc. (MapReduce Infrastructure Team) May - Aug 2012
Worked on the messaging layer of a new implementation of MapReduce, resolved coordi- nation issues using Google’s coordination service Chubby.
• Software Engineering Intern at Airties (R&D Department, Wireless Video Transfer) Aug - Sep 2008
Worked in a project for designing an open, extensible wireless home router intended for academic research. Took part in structural design and testing of the project. Prepared usage guidelines and documentation.
• Software Engineering Intern at Mobilera (Software Development Department) June - July 2008
Designed and implemented an online, interactive game software. Prepared documentation for continuation and linking of the project.
• IT Intern at Alcatel-Lucent (IT Department) July - Aug 2007
Worked in a project for creating a personal inventory of employees. Took part in the design and creation of the dataset and the database system.
