The resume of a passionate & curious problem solver.

My Code and Contributions

“The more that you read, the more things you will know. The more that you learn, the more places you'll go.” -- Dr. Seuss

From work to recreation I take pride in what I do. These are just a few examples of times I went the extra mile, and what I learned from it.

I started learning Python and Java independently in 2009. Since then I have kept up a rapid pace; Learning, experimenting and playing. I consider my ability to learn and desire to grow as my biggest assets.

Ask me what I'm learning now?

libc++ is a C++ standard library that ships on Apple, FreeBSD, Android, and inside Google. I'm a primary contributor to libc++. Along with bug fixes and maintenance I focus on adding support for newly standardized libraries. This includes a large section of the library fundamentals technical specification. I also contribute patches to other projects under the LLVM umbrella.

C++ Contracts
Clang Implementation

Contracts are new feature targeting C++26 allowing safer and more expressive code.

I'm excited to bring a production ready implementation to a compiler near you!

The C++ Standard
Documentation

I'm a member of the C++ Standard Committee. I work to improve standard C++ and it's libraries. I usually sit in the Library Working Group and help standardize libraries for new versions of C++. I also help triage and fix issues in the existing standard.

constinit
C++20 Feature

`constinit` is a C++ keyword which I designed and implemented in Clang before proposing for C++ standardization. The feature was accepted into the C++20 standard and is now available in all major C++ compilers.

Having your own C++ keyword is pretty cool

Experience & Responsibilities

Bloomberg LP (Contract)

C++ Contracts In Clang

I'm chiefly responsible for the implementation of C++ contracts in Clang. This requires both a deep technical understanding of the C++ standard and Clang's internals, and communication & community management skills to ensure the feature is well received.

Healthier Code

Overall, my work focused on producing a healthier codebase using changes to the C++ standard, hardening of the standard library, and deploying clang tooling at scale.

  • C++ Core Libraries & Large Scale Changes

    Contributed to the development of core libraries, focusing on enhancing performance and stability.

  • Large Scale Changes & Clang Tooling

    Created & Deployed new tooling for analysis and refactoring of Google's 100M+ lines of C++ code.

  • C++ Performance Improvements & Microbenchmarking

    Investigated, designed, and tested performance and memory improvements across Googles most widely used and performance sensitive C++ libraries.

  • Libc++ Releasing

    Supported & unblocked the weekly toolchain integrate & release with time-critical debugging and bug fixes of libc++ & other core C++ libraries.

  • Libc++ Kubernetes Infrastructure

    I maintain multiple Kubernetes clusters for libc++, supplying most of the testing infrastructure. This taught me how to manage, upgrade, and maintain services at scale.
