The challenge
top.legal manages the full contract lifecycle (creation, negotiation, signing, analysis) for enterprise teams. Contracts are unforgiving: extraction has to be accurate, collaboration has to be real-time, and downtime is a dealbreaker for legal workflows.
The platform needed to process a growing document volume reliably while supporting live multi-party contract negotiation.
What we built
A distributed processing pipeline
Node.js/TypeScript microservices handling 1,000+ documents per day at 99.9% uptime, with automated data extraction feeding the platform's contract intelligence.
A legal knowledge graph
A Neo4j graph of 100K+ legal entities with custom Cypher queries, powering portfolio-wide contract queries and risk identification.
Real-time negotiation
Collaborative contract editing via Operational Transformation (TipTap + WebSocket) supporting 20+ concurrent users in live dealrooms.
Event-driven re-architecture
Led the migration to AWS EventBridge and Step Functions, cutting processing time 70%, while mentoring a team of six engineers.
Results
- 1,000+ documents/day processed at 99.9% uptime
