KUBRA Innovation & Technology Culture

Describe a project you’re especially eager to tackle in the new year.

On our messaging team, we are excited to architect and deliver a new service responsible for sending timely payment reminders to end users with upcoming bills. This platform will process and deliver millions of notifications per day across multiple channels, which requires a highly resilient and scalable system design.

We’re implementing a multi-stage validation pipeline that performs over a dozen checks on consumer data, billing metadata and delivery eligibility. Each step must execute with low latency and high accuracy to ensure we’re generating the right reminder at the right time. We’re also building robust safeguards to eliminate single points of failure, including distributed message queues, retry logic, redundancy across services and proactive monitoring to detect anomalies before they impact users.

This is the kind of engineering challenge that excites me: high-volume event processing, fault-tolerant architecture and system-level thinking. The work directly supports our broader goals around customer engagement and reliability, and it allows us to meaningfully improve how millions of people interact with their bills and payments every day.

What technologies and/or practices is your team leveraging to tackle this project?

For this service, we’re integrating Temporal.io to significantly increase reliability and consistency across our workflow orchestration. Given the volume of end-user accounts and billing data we need to process, our system relies on a network of microservices that independently manage payments, account details and delivery logic. While this architecture enables scalability, it also introduces numerous potential failure points.

Temporal allows us to solve this in a clean and robust way. We can create durable workflows that maintain state for each notification, pause them for hours or even weeks and reliably resume exactly where they left off. This ensures that any platform outages, microservice failures or transient network issues during the dormant window do not impact the final delivery of a payment reminder.

Another key factor in choosing Temporal is its built-in support for retries, backoff strategies and failure recovery. Instead of engineering our own orchestration and reliability layer, Temporal provides these capabilities out of the box, dramatically reducing development time during a critical phase of the project. In short, Temporal gives us a fault-tolerant foundation for high-volume event processing, which aligns perfectly with the reliability requirements of this system.

How does this project tie into larger company goals?

By designing this service with strong reliability and state management in mind, we can ensure that every notification is delivered on time and with the correct information, no matter what occurs in the system between receiving bill data and the scheduled send. That level of consistency is essential. Even a single missed or inaccurate reminder can create confusion or frustration for an end user.

Providing a high-quality experience is a core priority for us at KUBRA. We want every interaction to reinforce trust and make it easier for people to stay informed and in control of their payments. This project is an important step toward strengthening that commitment and delivering dependable, user-focused solutions at scale.
