CRM SaaS Platform with Transactional Payment Flows

Engineered high-performance multi-tenant platform infrastructure written in Go and TypeScript capable of supporting concurrent real-time actions for 1,000+ active users.

01. The Problem

Legacy monolithic architecture failed to scale horizontally during peak loads, resulting in cascading failures across downstream services. Thread contention in the primary message broker and lack of backpressure mechanisms.

  • Critical scaling constraints required immediate re-architecture.
