Goldman Sachs

As a Senior, and later Principal Software Engineer at Care.com, Jae works on the front end Platform Team, maintaining and extending shared TypeScript-first React and Node libraries that power feature development across the organization. Her work emphasizes developer experience: authoring documentation, improving type hinting, running internal workshops, and leading engineering guilds to drive adoption and consistency.

Throughout both roles she operated as a bridge between design and engineering — translating design intent into precise, intentional front end implementation.

She brought accessibility into the development process and communicated directly with client stakeholders to align technical decisions with product goals.
