• Designed FlexoGraph: an ACID-compliant Graph Database that uses WiredTiger as the storage engine that performs better than existing specialized graph processing systems or graph databases. We provide multiple optimized data layouts, persist algorithmic state for bootstrapping future computations on new snapshots, and use lockless algorithms.

• Studied the implications of translation architecture on the performance of SMR drives and showed that a host-based log-structured translation layer can reduce the p99 latency by 50×.

• Benchmarked graph processing systems to understand the latent impact of statistical properties of the datasets on the performance of these systems and identified a set of best practices for benchmarking graph processing systems

I worked on the Trusted Capsules project. Trusted Capsules provide graduated access control on remote devices.

• Uses Linaro OP-TEE to manage fine-grained and trackable access to data on remote devices by linking the data to its access policy and encrypting them together
• Leverage FUSE to intercept operations on encrypted files to facilitate their on-demand decryption and re-encryption using the trusted application running in the Secure World
• Prototype written in C using a LeMaker Hikey board with ARM TrustZone and Linux 4.15.

Responsibilities include:

• Worked on Unified Host Utilities Kits for Linux and Unix – a tool for checking the health of storage on the OS when connected to NetApp storage controllers. It provides path and state information for all NetApp LUNs present on a host by issuing queries to the Host Bus Adapter API libraries.
• Handled infrastructure orchestration and configuration management for interop QA infrastructure.
• Designed and developed SAN Host Remediation Tool that automates the tasks to be performed on hosts when the storage migrates from NetApp 7Mode Data ONTAP to Cluster Data ONTAP. Supports all major host OS variants
• Designed and developed iLAB – a framework that handles dynamic testbed creation, resource allocation and initialization, test execution, and testbed tear-down. Increased execution efficiency by 95%
• Wrote Python and Perl scripts and libraries to test the interoperability of new Linux host and Data ONTAP features Depths, etc

I was the Teaching Assistant for CPSC 508: Advanced Operating Systems This seminar-style course introduces students to the theory and practice of conducting systems research. The papers discussed cover the history of operating systems research with a special emphasis on understanding what constitutes systems research and how it has evolved.

As a Teaching Assistant, I help students with their assignments and term projects - right from defining scope to finding the right compute resources for them to use. I also ran tutorials to bring the undergraduate students up to speed so that they can have a richer learning experience.

I was the Teaching Assistant for CPSC 319: Software Engineering Project at UBC from September 2017 to April 2018. This course provides an opportunity to undergrad students to design, implement and test on a large software system for an industry sponsor. The focus in this course is to apply waterfall SDLC methodology to the solution from inception to production, producing key documentation artefacts while working in a team.

I acted as the industry sponsor liason and “engineering manager” to the teams. Over the course of the year, I overlooked two projects and managed about 40 students.

• Managed two teams implementing a self-service tool for Uniserve clients and IT support staff.The tool allows the IT staff to manage their devices and see real time information about their network health and usage trends.

• Supervised two student teams implementing a self-checkout and payment portal for ChainXY.
