Teams at Infinity Constellation

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.

Work directly with customers to map regulated operational workflows, implement production-ready full-stack slices (frontend, backend, data, integrations), verify with tests and logs, demo results, and translate field learnings into reusable product primitives and roadmap decisions.
