Description

BriefOS is an AI platform for performance marketing teams. It breaks down why an ad converts — scene by scene — and turns those insights into creative briefs their team can actually produce against.

I built the web platform from the ground up in Next.js as the sole frontend engineer, owning architecture, the design system, and a reusable component library on top of Material UI. The platform serves 150+ paying brands.

Responsibilities

  • Platform foundation — Built the web platform from the ground up in Next.js, enabling 150+ paying brands to run AI-powered ad analysis and creative brief generation.
  • Frontend ownership — Owned the entire frontend as the sole frontend engineer: architecture, design system, and a reusable component library built on Material UI, with server state managed via Redux and RTK Query.
  • AI video analysis view — Developed the interactive analysis view that shows brands why an ad converts: scene-by-scene marketing breakdown of video frames and the audio script.
  • Stripe subscriptions — Implemented the full subscription experience with tiered plans (Core / Pro / Agency) and usage-based plan limits surfaced across the app.
  • Creative brief workflow — Shipped the brief generation workflow along with a chat interface for AI-powered brief revision.
  • Spy competitor tool — Created the competitor research tool on top of the Meta Ad Library API, enabling page tracking and filtered ad discovery.
  • Infrastructure & observability — Set up authentication with Clerk, deployments on Vercel via GitHub Actions, product analytics with Posthog, and error monitoring with Sentry.
