Jacqueline Firth’s Résumé🔗

jackhfirth@gmail.com, (760) 902-4112

Experienced software engineer specializing in developer tooling, compilers, CI/CD systems, programming language theory, functional programming, automated refactoring systems, macro systems, microservices, and large-scale distributed systems. Currently based in the San Francisco Bay Area.

1 Experience🔗

• 2017 to Present — Software Engineer at Google on the Test Automation Platform (TAP) Postsubmit team in Mountain View and Sunnyvale, CA. I worked in Java on backend microservices implementing the test scheduling system Google uses to execute all of Google’s unit tests, running billions of tests per day. I’ve designed and implemented queueing systems, ML-based predictive scheduling systems, high-throughput stream processing systems, and numerous libraries and tools to manage our team’s multi-million-line codebase. I am the team’s resident expert on asynchronous programming, concurrency, data structures, static analysis, and testing infrastructure.

  In addition to my work for my team, I’ve contributed to Google’s standard Java libraries, frameworks, and analysis tools, including Guava and ErrorProne. I’m also one of Google’s Java readability mentors: a collection of a few hundred engineers who educate the rest of Google’s developers on Java style and best practices through code review and Google’s "readability review" process.

• 2016 to 2017 — Software Engineer at Google on the Google Cloud Elysium team in San Francisco, CA. I implemented various backend server components of Google Cloud’s resource administration APIs, paritcularly the Cloud Project, Folder, and Organization APIs.

• 2015 to 2016 — Software Developer at Mindjet in San Francisco, CA. I did full stack development on Mindjet’s experimental new web platform for business task management. We worked with Mongo, NodeJS, and Angular in a functional programming oriented style. I gave multiple seminars on functional programming concepts generally and on Haskell specifically to our team to educate our developers in this style.

• 2014 to 2015 — Programmer at CenterSoft in Cathedral City, CA. I did full stack development on the company’s flagship accounting software, working with C#, MySQL, and frontend web technologies.

2 Education🔗

Bachelors in Mechanical Engineering with minors in both Math and Physics from SUNY Canton, NY (2009-2013), supplemented by Computer Science courses taken through a cross-registration program at St. Lawrence University, NY (2011-2013). My education was unusual: I was 14 years old when I began taking SUNY Canton classes full time, and at the age of 18 I had to leave my bachelor’s degree program without finishing it due to life circumstances.

3 Projects🔗

• Racket — A Lisp/Scheme-like programming language with an advanced macro system designed for creating entirely new programming languages. I am a frequent contributor to Racket and its ecosystem. I’ve given numerous talks at RacketCon, many of which are viewable on YouTube.

• Resyntax — A static analysis and refactoring tool for Racket that transforms Racket’s macro system into an automated refactoring platform. Multiple core Racket projects rely on its integration with GitHub.

• Rebellion — A collection of core libraries for Racket created entirely by myself. Includes core data structures, stream processing libraries built around transducers, concurrency primitives, and various other useful libraries.

• Rhombus — An experimental research language built on Racket with the intention of bringing Racket’s macro system to non-S-expression languages. I am a contributor and frequent design discussion participant. I am one of the authors listed on the OOPSLA23 paper on Rhombus, although I am listed under my previous name (Jack Firth).
