For a semester, I was a TA for the Computer Security class at Berkeley (https://cs161.org). This involved running weekly a discussion section, my own office hours, and generally being available - Piazza, in person - to help students with their homeworks, projects, and other questions they might have on class material. We cover topics such as (but not limited to):

• Software vulnerabilities (taught primarily in C) and how to exploit them

• Software defenses (ASLR, NX, canaries, memory safe languages)

• Cryptography (block ciphers, encryption schemes, public key, signatures)

• Network security (TCP/TLS, DNS/DNSSEC, SQL injections)

• Web security (CSRF, XSS, cookies, phishing)

• Miscellaneous security topics

My primary project at Facebook involved working with Marketplace image enhancement code. I first had to generalize Marketplace image enhancement code in order to work for more objects. I modified code on the objects themselves, the code that the frontend used to query for these objects, as well as the image enhancement code itself. After the generalization, I backfilled the ~40 million objects newly eligible for enhancement, and ran an A/B test to confirm the new code creating and serving enhanced photos was generating only neutral or positive results.

I finished my project early, and so had time to work on a few other tasks. The significant one out of these was a mini-project to add additional logging to Marketplace's composer. I added frontend click logging for when users selected certain options on the composer for mobile (iOS and Android) and on web, and added fields to existing backend logging after users submitted their items to Marketplace. This new data is used in Marketplace metric analysis.

I worked with Pantheon, a website-hosting platform, through one of my organizations at Berkeley. We agreed to build a project manager dashboard for them through the semester using Go, React.js, and Firestore as our database. This dashboard combines several software management services including GitHub, Jira, and Pantheon's own platform data in order for project managers using Pantheon to more easily oversee progress and completed work. We received data from service webhooks on our backend, and simultaneously piped that data into our database and sent the data along websockets to our active clients for real-time updates on the dashboard.

My role in this project was first as the project architect. Along with my co-project manager, we discussed and planned out the full tech stack, file organization, deployment/development pipelines, and any other smaller technical details.

We onboarded 5 developers to the team and acted as project managers for the rest of the semester. We broke down the project into week-by-week tasks, provided technical workshops and office hours for our developers, and generally managed the project to ensure smooth and steady progress through the semester.

I worked with BetterCloud, an operations management platform provider, through one of my organizations at Berkeley. I worked to integrate BetterCloud's service for creating/executing IT workflows into ServiceNow, another IT management tool - I used ServiceNow's extensive API to combine the two services into one seamless experience. For example, their GlideRecord API serves as a delegate to send and receive BetterCloud IT workflow objects to and from the database. This project follows a serverless architecture using Google Cloud Platform.
