New York, New York, United States
Summary
🤩
Rockstar🎓
Top SchoolKyle Nekritz is a software engineer with 12 years of production experience, currently building secure, high-performance backend systems at Facebook in New York. He specializes in C++ systems programming and TLS/HTTP transport layers, with notable open-source contributions to widely used Facebook projects like fizz, fbthrift, proxygen, wangle, and folly. His work focuses on hardening security, improving TLS implementations, and refining server transport and session handling—often addressing portability, edge cases, and performance trade-offs. Trained as a computer engineer (BSE) with an MSE in CSE from the University of Michigan, he has a background that blends low-level networking, protocol correctness, and pragmatic engineering for large-scale services. An underappreciated strength is his attention to subtle operational details—build portability and Android-specific fixes—that keep complex distributed systems reliable in the real world.

Aug 2015 - Jun 2020
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 & Security Engineer
Back-end Developer & Security EngineerContributions:42 commits in 4 years 10 months
Contributions summary:Kyle's contributions primarily involve enhancing the security and functionality of the Wangle framework, specifically focusing on TLS (Transport Layer Security). Their work includes logging TLS signature algorithms, enabling client hello parsing by default, and adding a framework for switching certificates based on the signature_algorithms TLS extension. Additionally, the user refactored the acceptor code to allow for more flexibility and also removed older APIs in favor of newer alternatives.
