Hello! My name is Jessica Sachs.

I go by jess she/her pronouns.

I write open-source developer tools for the web.

I’m currently at Cypress as a Staff Eng. where I design and lead the development of the Cy Component Test Runner. I’m a Vue team member, working on the Vue testing ecosystem. I’m a contributor and enthusiast of both Vitest and Vite.

Recently I re-launched a fork of Faker.js after it was (infamously) abandoned in January 2022.

You’ll find me on Twitter (my DMs are always open, here’s how to get a good response) and Discord.

I speak about testing, open source tools, and Vue.js. I’m also a fan of Vite, WindiCSS, and Vitest.

A few times a year, I teach workshops at conferences in the US and sometimes abroad. Usually about Vue, but sometimes about other stuff – working with bundlers, building style guides, or refactoring legacy code.
