    Senior Frontend Software Engineer

    Mar 2026 – present · 7 months

    Rebuilding the frontend from its foundations: off Create React App, onto React 18, Vite and Tailwind in a Turborepo monorepo.

    What I did

    • Built the shared UI, lint, types and docs packages the other apps use
    • Kept Cassandra’s data-heavy graphs shipping through the whole move
    • Planning the state migrations off Redux: TanStack Query, faster loads

    What I did

    • Built the Polls sub-product: the builder, the views and its billing
    • Ran the board in Asana, reviewed the code, mentored the engineers
