Future-Proofing Procurement Tech: How HattiOps Scaled Notifications Seamlessly

Meet Mr. Shasedaran KKS, the founder of HattiOps, a company on a mission to simplify procurement processes for corporates. With over five years in business, HattiOps has helped streamline sourcing and purchasing across industries.

The Problem: Flexible Notifications

When we first met Shasedaran and his team, they had a clear vision: to build a digital platform that could manage RFQs and estimates between corporate purchasing heads and vendors.

But they had a smart approach—they wanted to build the system in phases, integrating key capabilities one step at a time. One such feature on their roadmap was notifications.

At launch, only email notifications were needed. But they knew this would expand: WhatsApp and SMS were in the pipeline. So the challenge was clear: design the system to be flexible enough to support future channels—without rewriting the application every time.

The Solution: Event-Driven Notification Service

We got to work by designing a notification service built on an event-driven architecture.

This means the core application doesn’t directly handle how notifications are sent. Instead, it emits events—like “RFQ Created” or “Estimate Approved”—and independent listeners handle what to do next. Initially, we wired up the email notification listener. Later, when the client was ready, we plugged in SMS and WhatsApp listeners—without touching the core logic.

The Result: A Scalable, Modular Notification System

Because we architected the system with future growth in mind, HattiOps was able to seamlessly add new notification channels as business needs evolved. There was no need to refactor or rework the application. Just plug-and-play.

Why This Matters

Too often, early design decisions limit future flexibility. But in this case, a future-proof architecture gave HattiOps the ability to move fast, stay lean, and adapt as their platform grew.

At its core, this is what good software design should enable: agility, not rigidity.
