I was a founding engineer on the JavaScript Infrastructure team at Stripe. I did whatever it took to make JS devs at Stripe write higher quality code, be more productive, and worry less about maintaining their own tooling. Over the course of my four year tenure, I led and contributed to many projects that established JavaScript as a first-class supported language. Here are some highlights:

• Created a JavaScript CLI tool used daily by ~600 engineers. It managed JS projects integrated with pnpm, Bazel, and our remote execution infrastructure. It enabled a true monorepo setup that previously was not possible at Stripe.
• Created and maintained a set of centralized JS dependencies used by monorepo projects. Folks could use the shared tooling without worrying about managing their own test runner, linter, code formatter, build tooling, and typechecking. Customer teams got upgrades for free.
• Migrated our largest JavaScript codebases (over 4 million lines of code) to a new development optimized bundler that sped up initial development times by 20x.
• Improved our remote execution system (featured in this YouTube presentation) that decreased Bazel memory (20GiB -> 10GiB), sped up JS execution by 10% (in common cases), and improved sandbox setup up to 5x for JS projects. This involved writing low-level Go code that performed syscalls within Firecracker VMs.

Originally hired on as a front-end engineer to work on the main UI product that was written in PHP and jQuery. Helped form a grassroots movement to convert UIs to React. Helped drive React adoption that ultimately decreased bugs and improved developer velocity. Authored two large React component libraries: Lucid and its extension that was proprietary and internal. Gave two (1, 2) public presentations about Lucid.

Helped evaluate and was the first engineer to run production services on Kubernetes at the company. Helped lead a large project that migrated the entire UI stack to Kubernetes; the net result was a geographically redundant system that was more reliable than our previous homegrown solutions. Other highlights:

• Worked on a TypeScript, Hapi, Node.js API that was in the critical path for all our microservice UIs.
• Authored and contributed to the Ankh tool written in Go which became the de-facto deployment tool for Kubernetes services within the company.
• Wrote and maintained a CLI that bootstrapped UI apps when the company moved to microservice UIs.

Built a web application to manage thousands of internet connected Android devices in the field around the US. The web app was written in Angular and backed by Node, a Java API, and Elasticsearch. It was built using Node, Hapi, Angular, and Bootstrap CSS.

Rebuilt the company's EC2 infrastructure by implementing Ansible to build and mange all servers on CentOS. This enabled the company to have isolated, reproducible, and automated environments. Also introduced and championed the use of HipChat and hubot to deploy applications.

Helped manage and prioritize scrum sprints. Mainly involved triaging tickets in Jira and discussing software development priorities with management.

Built a new responsive website for CSG based on designer specifications. Used the following technologies: Node, Express and Azure. Built the company's first HTML5 dashboard with a Node back-end. Used client side JavaScript to create rich interaction and data filtering using AJAX, JavaScript, and JSON over HTTP.

Moved web development forward at CSG by educating peers and introducing client-side MVC and CSS frameworks to several projects.

Worked as a consultant on various kinds of analytical projects ranging from enterprise data warehousing to real-time dashboards. Built OLAP cubes and data visualization solutions. Worked as the lead consultant for several companies in the Portland area on data projects relating to supply chain management, logistics, political canvassing, manufacturing, and distribution. Improved internal reporting and visibility for CSG through a series of automated reports and ETL processes.
