Own and build the greenfield B2C backend: schema-first TypeScript BFF, OpenAPI contracts, Cognito-based auth, Postgres domain models with forced RLS, durable asynchronous operations (transactional outbox, SQS, worker leases), Python worker integration, observability, compatibility/versioning, tests, runbooks, and handoff documentation.

Contract frontend engineer to build a greenfield B2C patent-intelligence UI using React/Next.js and generated OpenAPI clients. Responsibilities include onboarding flows, Cognito sign-in, guided streaming exploration with resumable SSE, account/membership UX, public-graph visualizations, Stripe test-mode billing UI, performance optimization, and test/E2E coverage.

Lead end-to-end product design for verticals or platform surfaces, turning ambiguous regulatory workflows into build-ready prototypes and reusable design systems. Drive accessibility (WCAG 2.2 AA), conduct remote user research and usability testing, pair with front-end engineers on component-driven implementations, and raise design craft across the team.
