Experience
Security Engineer in Meta's Applied AI (AAI) / Agent Data Optimization (ADO) organization, focused on generating high-quality cybersecurity training data for LLMs. Previously on Red Team X, Meta's former offensive security research team.
At Stratum Security, I provided staff augmentation for a major company, conducting security reviews of high-traffic, externally facing applications. Through manual code reviews, dynamic testing, and threat modeling, my work played a critical role in safeguarding the privacy and security of millions of users worldwide.
I helped Fortune 500 companies secure their networks by performing penetration tests and security reviews of internal and external applications.
I independently identified and gained recognition for finding vulnerabilities in web applications and embedded devices. I wrote comprehensive bug reports and notified vendors under a 120-day disclosure policy. I am credited with finding CVE-2020-8797, CVE-2020-8798, CVE-2020-12123, CVE-2020-12124, CVE-2020-12125, CVE-2020-12126, and CVE-2020-12127. I engaged as a member of the prestigious Synack Red Team (SRT) and contributed to the Google Vulnerability Reward Program (VRP), successfully identifying and responsibly disclosing high-risk vulnerabilities.
In the first summer, I researched and found security vulnerabilities in various commonplace embedded devices and developed tooling to exploit those vulnerabilities. In the second summer, I gained experience with JavaScriptCore and V8 vulnerability research and worked with a team to find high-impact bugs.
I evaluated the security of devices on the Virginia Tech network. I developed tooling to facilitate embedded device research. I found numerous high-impact vulnerabilities, notified impacted departments, and worked with them to mitigate the issue.
I worked under the Virginia Tech Computer Science Department, fulfilling 10 hours a week as an undergraduate TA, and helped students in one of the most challenging courses in the CS curriculum, Computer Systems. I learned how to isolate bugs in student code and effectively teach systems-level concepts. I became an expert in debugging in GDB and programming in low-level C.
In the first summer, I worked on a team to develop a mobile application from scratch. In the second summer, I led a team creating embedded systems to collect data.
