I'm at the heart of Meta's security & privacy infrastructure, focusing on building frameworks and implementing foundational changes across our family of apps to deliver scaled security benefits. Here are some highlights:

* Drove Instagram's migration to 100% HTTPS, a critical move to secure user data.

* Authored Instagram's cookie management framework, strengthening privacy controls.

* Enhanced Django's CSRF prevention framework, a key aspect of web security.

* Collaborated on Trusted Types for Python in FB, an innovative approach to security.

* Built infrastructure for securing TLS keys and led code signing security initiatives.

* Developed authentication infrastructure for Reality Labs, enabling the rollout of Meta accounts that operate at the company level.

I've had the opportunity to work with technologies like Python, Hack/PHP, & C++, crafting solutions that uphold our commitment to security and privacy.

* Developed automation to detect subdomains vulnerable to hostile takeover, allowing us to remediate them proactively.

* Co-managed the company's Whitehat Bug Bounty program, leveraging crowdsourced ethical hackers to identify and remediate bugs.

* Conducted security reviews to ensure our products are polished, high-quality, and shipped with minimal security vulnerabilities, reflecting our commitment to excellence.

Tutored CS1010FC (Programming Methodology; Python), CS2020 (Accelerated Data Structures & Algorithms; Java), CS2107 (Introduction to Information Security), and NUS Orbital (Workshop on Web Security).

Developed a JavaScript source code analyzer that outperformed existing open-source alternatives. Using taint analysis and pattern matching, it detects vulnerabilities and security misconfigurations in NodeJS applications.

Enhanced the detection capability of FireEye's MVX™ engine through insights gleaned from in-depth malware analysis and research on malicious URL classification. Main technologies include IDA Pro, Wireshark, Python and WinDbg.
