• Achieved a 60% reduction in the time taken for upgrade operations in our fleet - we designed and implemented a new mechanism for upgrade in a team of 4.
• Planned and executed the deployment of migration of the OS used across our SaaS fleet in a team of 2 as the current one was nearing EoL.
• Achieved a 90+% reduction in the number of disk full alerts for our SaaS fleet by analyzing and identifying patterns and fixing them. Disk full alerts were a big problem for our SaaS fleet due to legacy reasons and were causing significant operational overhead.
• Improved build times by 40% by identifying inefficiencies and removing them. The build scripts had unnecessary calls for forking and doing an operation that was no longer needed, but the performance penalty was not visible to folks.
• Achieved a 11% reduction in our release size by identifying and fixing redundancies. Ensured that a release size gate was introduced to avoid hitting issues in the field and production while we transform to a different form of delivery.

• Graduate Student Researcher at the PLSysSec Lab at UCSD. Worked under the guidance of Prof. Deian Stefan and Shravan RN in investigating and implementing optimized bounds check for pointers in Chrome. The optimization in this case was a result of hardware advancements - specifically Memory Tagging Extension in ARM. Due to the complex nature of the project, I was unable to see it through completely.

• Interned with the Curated Ads Data team under the Responsibility and Privacy Engineering organization.
• Designed and implemented automation framework to generate, run and validate data pipelines which enabled the creation of curated data sources (standardized, regulated retention, purpose-specific) from the data in the warehouse.
• Increased engineer productivity is 15x with the above automation; additionally, will help team to meet the long-term goal of curating different data sources.
• Ideated, scoped, designed and implemented a purpose policy sync and notification solution for the curated tables that the team had been creating. This involved creating a monitoring dashboard and a bot to take corrective actions on detection of any discrepancies between the decided and applied policies. The completion of the dashboard led to identification of several such discrepancies. Due to time constraints the bot could not be completed.

• Developed a workflow automation tool. It allows users to create workflows specific to vSAN by dragging and dropping elements and connecting them. These workflows can then be executed on testbeds allowing for better productivity of engineers instead of writing test scripts.

Aug 2019 – Jan 2021 · 1 yr 5 mos

• Worked in the security infrastructure team for IOS-XR - handled the attestation infrastructure. IOS-XR attestation allows customers to verify the software and hardware they are using and running is trusted. Defined and implemented workflows using which customers could verify the hardware root of trust, and software running on it.
• Won the SecCon APJC CTF challenge, 2020 in a team of 4. SecCon is Cisco's Annual Security Conference. There were 2 rounds in the CTF challenge - first one was a jeopardy round and the second one was an attack-defence round. We achieved the 3rd position in the first round, and the 1st position in the second round.
• Working on improving the scale and performance of reporting of IMA logging from IOS XR to Cisco Crossworks (Trust Insights) in a team of 4. The kernel was modified to make the logs available to user space as signed protobuf blocks, the user space was modified to read these blocks, perform disk based caching and stream the requested data. As part of this, we also added a configurable CRON job to perform caching instead of doing that only when a request was made from Trust Insights.
• Achieved removal of duplicate symbols of the OpenSSL libraries in XR. This was a long standing problem in the XR security team. The team had made several attempts at achieving this but had been running into road blocks. I came up with a new approach, prototyped it and drove the activity to completion.
• Designed and implemented Secure Storage as a Service on XR. This was picked up by marketing as a feature to be provided to customers post our prototyping for the SP Innovation Challenge. This service aims at providing customers running 3rd Party Applications on their nodes to securely store secrets into Cisco's TAm (Trusted Anchor Module) based secure storage using the well known APIs of Hashicorp's Vault.
• My responsibilities also include maintaining and fixing SSH, MPP (Management Plane Protection) on XR.

• Replaced proprietary implementation of SSH on XR by integrating OpenSSH into XR with complete backward compatibility in a team of 5.
• Focussed on SSH on XR - improving and maintaining SSH on XR.
• Volunteered to be a part of the XR Memory Diet Team, tasked with the objective of reducing the memory footprint of XR processes. As part of the team, built a web-based dashboard that enables the engineers to visualize the memory footprint of the processes. The dashboard consists of various graphs and information that helps the various program and project managers to draw insights from it.
• Won the Service Provider Innovation Challenge, India, 2019: As a team of 4, we designed and prototyped the system to expose XR's Secure Storage (TAM) to 3rd Party Applications via a gRPC interface. This creates a monetizing opportunity for Cisco as it could be sold as a service to customers.
• Won the Service Provider Innovation Challenge, India, 2018: As team of 2, we ideated, designed and implemented a web based dashboard which allows XR engineers to visualize static dependencies and linkages among XR Processes, Libraries and APIs.
• Worked as an engineer in the GMPLS team for IOS XR, Cisco's Operating System for routers catering to the needs of Service Providers.
