Enterprise SaaS Platform
Precision-engineered web services and reactive event-driven pipelines built for scale.
Project Description
High-Throughput Architecture
The client required an ultra-responsive, multi-tenant B2B platform capable of processing complex transaction calculations in real time without sacrificing UI fluidness or data isolation.
Citi Solution engineered a high-velocity web platform powered by Next.js 16, TypeScript, and Node.js microservices. The architecture leverages partitioned PostgreSQL schemas for tenant isolation and Redis message streams for event-driven synchronization.
The resulting system delivers a 10x throughput increase, upholding sub-100ms Core Web Vitals and providing enterprise clients with customizable dashboards, strict role-based access control, and bank-grade data security.
