Summary
👤
Senior🎓
Top SchoolAnirudh Ramachandran is a seasoned software engineer and tech lead with 15 years of experience specializing in systems and network security, currently leading Edge Security and Anti-DDoS efforts at Meta in the San Francisco Bay Area. He blends deep research roots—a PhD from Georgia Tech—and startup experience as a Y Combinator-backed founder with hands-on engineering across transport security, TLS, and large-scale server infrastructure. An active C++ open-source contributor, his work has improved TLS/SSL handling, async OpenSSL support, and probabilistic cipher selection in high-profile Facebook projects like folly, proxygen, wangle, and fbthrift. Colleagues rely on him for pragmatic, low-level fixes that materially harden connection security and performance, from session-ticket handling to flow-control tweaks for HTTP/2. Not actively looking for opportunities, he nevertheless continues to shape foundational networking security primitives used in production at web scale.

Jan 2016 - Oct 2018
Wangle is a framework providing a set of common client/server abstractions for building services in a consistent, modular, and composable way.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:18 commits, 29 comments, 4 issues in 2 years 9 months
Contributions summary:Anirudh primarily contributed to the `wangle` framework, focusing on SSL/TLS-related features and configurations. Their work involved modifying SSL context configurations to support key offloading, improving the handling of ECDSA async/offloading for proxygen, and refactoring OpenSSL-specific code. Furthermore, they made several updates and improvements to the SSL context and related utilities, including adding support for probabilistic cipher selection.

Nov 2015 - Dec 2019
An open-source C++ library developed and used at Facebook.
Role in this project:Back-end Developer & Security Engineer
Back-end Developer & Security EngineerContributions:25 commits, 2 comments in 4 years 1 month
Contributions summary:Anirudh primarily contributed to the `folly` repository, focusing on enhancements to the `AsyncSSLSocket` class. Their work involved modifying and refactoring OpenSSL-specific code, including the implementation of features like server-side certificate getters and the ability to probabilistically choose server ciphers. Furthermore, they made modifications to support OpenSSL 1.1.0's async API and addressed security concerns by introducing a SHA-256 digest for certificates and adding application-generated alert strings during handshake, indicating expertise in securing SSL/TLS connections.
