Cyber Security Intern

Foster City, California, Us

I primarily worked on developing a Web Application Firewall coverage analysis tool that provided capabilities to query and visualize the existing rules for various public facing endpoints. This helped bring down security vulnerability risk triage time by almost 50%.I also helped develop an in house Open Source Vulnerability alerting system which eliminated vendor dependence and cost.

Jun 2018 - Sep 2018

Graduate Teaching Assistant

La Jolla, Ca, Us

Worked as a Teaching Assistant (TA) for the Database System Applications undergraduate course. In this course students are expected to create from scratch a fully functional web application that makes heavy use of persistent data for querying and report generation. My responsibilities as a TA broadly involve clarifying questions brought up by students regarding the course material or general course logistics, coming up with evaluation rubrics and grading project demos and exams.This role has given me the opportunity to work as a team with my fellow TAs and professor to enhance the learning experience of a diverse group of students and in parallel to brush up on and hone my database and web application development skills.

Apr 2018 - Jul 2018

Software Development Engineer

New York, New York, Us

I primarily worked on developing software based end to end automation solutions in the database engineering space. This involved both front-end and back-end development along with DevOps. Worked as part of a diverse global team under rigid deadlines which demanded top notch collaboration and communication skills.

Jun 2014 - Aug 2017

Software Development Summer Intern

New York, New York, Us

I got the unique opportunity to work with the database engineering team as part of this internship. I was able to successfully deliver two projects within this span.As part of the first I developed a generic REST client in java, that could be used to interact with any web based API exposed within the firm. This helped reduce the team’s dependency on legacy SOAP based services and embrace the benefits which the REST architecture provided. This was a significant learning experience for me as I was new to both Java and the concept of web based services.The second involved performing network analysis in order to ascertain how much of load different data servers had to handle and allocate compute resources accordingly. I primarily worked on coming up with a proof of concept for the tool that would best suit this purpose. This involved researching and learning about various packet capture C libraries and Linux utilities.
