Work Experience
06/2022 - Present • Senior Software Engineer - Ad Hoc
- Senior Software Engineer on HealthCare.gov responsible for developing TypeScript/React and Ruby/Rails applications that enable millions of Americans to enroll in healthcare and minimize insurance costs. Spearheaded efforts in collaboration with Dev Ops team to containerize our backend Rails application, and migrate from a legacy webserver (unicorn) for full encryption over transit. Led a front-end migration from react-scripts 4 to 5 which reduced the lines of code in our application by 1237 lines, and enabled a migration to Vite. Introduced a performance enhancement by memoizing computationally expensive components on HealthCare.gov, reducing the render time of a major component by 80%. Created multiple enhancements to our deployment and testing pipeline such as: ANSI color outputs in our CI, disabling concurrent pull request builds to reduce CI load; enabled a workflow to only test affected libraries during CI; and authored a job to automatically build Docker images containing our dependencies to reduce time spent waiting for
npm installs on our jobs.
