Lit Sign is a full-stack platform for AI-assisted legal document creation and digital signing. I developed the Node.js backend handling contract generation, versioning, multi-party signing, and LLM-based clause negotiation. The frontend, built with React and Redux, enables users to manage contracts seamlessly.
