Cover image for Planet Console is a local-first
Planet Console is a local-first React and TypeScript workflow console for coordinating complex engineering task returns, review gates, and next-action handoffs. I built the modular UI, typed state and validation layers, local persistence safeguards, and verification workflow. The current implementation passes 16/16 automated checks, including lint, TypeScript build, persistence and contract tests, and UI regression coverage.
