Node.js Platform Rebuild
SaaS Platform
Voodoo AI rebuilt a struggling monolithic platform into an event-driven Node.js architecture capable of significantly higher throughput, lower latency, and faster product delivery.
Challenge
The existing monolith was struggling with poor latency under load, limited scalability, and feature delivery cycles measured in months.
Approach
We decomposed the system into 14 event-driven services, built a hardened API gateway, introduced observability and distributed tracing, and reworked critical data paths for scale.
Impact
The platform now supports materially higher traffic, better reliability, and a much faster delivery cadence for new features and integrations.
Results
10× throughput improvement (2,000+ RPS)
50ms p99 latency
Feature delivery in weeks, not months
99.97% uptime
