Event-Driven Backends for Real-Time Business

We build high-throughput, low-latency Node.js backends that power mission-critical APIs and streaming workloads.

Node.js apps built without proper patterns risk memory leaks, scaling issues, and inconsistent performance under load.

Our Approach

Framework Excellence

Use NestJS or Fastify for structured, high-performance APIs.

Event-Driven Architecture

Leverage Redis/Kafka for messaging and streaming.

Contract Testing

OpenAPI and Pact tests ensure integration reliability.

Observability Hooks:

Implement OpenTelemetry and autoscaling from day one.

Key Differentiators

Banks and NBFCs need a smart, scalable platform that treats DSAs like extended partners — with speed, transparency, and compliance at the core.

High Throughput Design

Worker pools and clustering for performance.

Security Baked In

Secret management and threat modeling included.

Scalable Integrations

Designed to plug into complex enterprise ecosystems.

Latency Monitoring

SLIs and SLO dashboards embedded in pipelines.

For today’s banking growth channels, the portal is no longer back-office tech — it’s the sales engine.
