Overview
An event execution web app for hosts: plan, invite, collect RSVPs and run the event end to end, with realtime guest updates.
Core features
Public event and RSVP pages, guest lists, sub-events, attendance check-in, payments, seating, custom forms, forecasts and post-event summaries, and a CMS for blog, help and FAQ content. My work covered a responsive-layout pass across the web app, an accessibility colour-contrast pass (a contrast helper plus adjusted colour tokens across the admin screens and shared components), a restructure of the workspace's app packages, and new integrations.
Architecture
A pnpm TypeScript monorepo: an Express 5 API on PostgreSQL with Drizzle ORM and session auth (Google OAuth and email), a Vite and React web app that uses an API client generated by Orval from an OpenAPI spec, Zod validation, Stripe with idempotent webhook handling, and a server-side OpenAI integration package.
