Overview

Digital Banking PLC was founded in 1983 as global markets's first private commercial bank. Over the past four decades, it has grown into one of the country's most prominent financial institutions, serving millions of individuals and businesses across a wide range of banking products.

As the bank expanded, its operations became increasingly dependent on two third-party platforms - Finacle and Ababil. These platforms handle everything from treasury bonds and loan approvals to account management and card processing. The problem was the pricing model. Both platforms charged per user, so every time Digital Banking added staff or expanded access, the licensing cost went up with it.

To solve this, Digital Banking started building a unified banking platform that would bring all these operations under one system. The platform had a wide scope, covering over 30 modules, and the internal team needed more engineers to keep up with the timeline. That's when they approached Prime Horizon for staff augmentation support.

Prime Horizon joined the project in January 2025, embedding six engineers directly into Digital Banking's development team. The engineers worked alongside Digital Banking's team to build and improve the platform, following the bank's technical direction while actively contributing to development. The project is still ongoing, with two Prime Horizon engineers continuing to work on the platform today.

Challenges faced by the Client

From initial discovery to ongoing support, Prime Horizon Technologies brings structure and care to software delivery. We translate business needs into maintainable applications designed to evolve.

1.A licensing model that kept getting more expensive

Work with a focused engineering team that fits your way of working. Shared priorities, open communication and regular reviews keep everyone moving toward the same goal.

2. No single place to see the full picture

With operations spread across multiple platforms, there was no centralised system of record. Data sat in separate silos, and teams often had to jump between tools just to complete one workflow. This made day-to-day operations slower and more error-prone than they needed to be.

3. Customers with multiple accounts were hard to manage

Many Digital Banking customers hold five or six accounts at the same time. Without a system that linked these accounts to a single customer identity, relationship managers had to look up accounts individually to piece together a full picture of any given customer. It was time-consuming and left room for things to be missed.

4. The platform scope was too large for the existing team alone

Work with a focused engineering team that fits your way of working. Shared priorities, open communication and regular reviews keep everyone moving toward the same goal.

5. Requirements kept shifting during development

How Prime Horizon Solved It

Prime Horizon came in as a staff augmentation partner, which meant working within Digital Banking’s existing team structure and following their technical direction rather than coming in with a separate approach.

1. Adding engineering capacity quickly

Prime Horizon deployed six engineers. Primarily backend developers, along with a full-stack engineer, who joined Digital Banking’s team and started contributing right away. This gave Digital Banking the extra capacity they needed without the time and overhead of hiring and onboarding new permanent staff.

2. Building the API layer that reduced licensing costs

From initial discovery to ongoing support, Prime Horizon Technologies brings structure and care to software delivery. We translate business needs into maintainable applications designed to evolve.

3. Building the 360 module for unified customer identity

Prime Horizon worked on the 360 module, which ties all of a customer’s accounts to a single customer ID. Instead of treating each account separately, the system now links everything under one identity. This makes it straightforward for relationship managers to see a customer’s complete profile without having to search across multiple accounts or platforms.

4. Taking ownership of key modules

Keep essential systems dependable with structured maintenance, clear documentation and responsive technical support. We help your team manage change with confidence.

5. Staying adaptable as requirements changed

Throughout the project, requirements evolved as stakeholder discussions progressed. Prime Horizon’s engineers adjusted to these changes without stalling delivery, staying in close communication with Digital Banking’s product team to keep development aligned with what was actually needed.

Core Features of The Unified Banking Platform

Unified multi-account management

Customers who hold multiple accounts can have all of them managed through a single interface. This removes the friction of handling accounts separately and gives staff a cleaner, more consolidated view.

360-degree customer identity

All accounts and interactions are tied to one customer ID. Relationship managers can pull up a complete view of any customer instantly, regardless of how many accounts they hold.

Treasury bond management

From initial discovery to ongoing support, Prime Horizon Technologies brings structure and care to software delivery. We translate business needs into maintainable applications designed to evolve.

Account lifecycle management

Account opening, maintenance, and closing are all handled inside the platform, covering the full lifespan of any account.

Loan workflow management

From initial discovery to ongoing support, Prime Horizon Technologies brings structure and care to software delivery. We translate business needs into maintainable applications designed to evolve.

Card and cheque handling

Card management and cheque requisition, processing, and approval are handled end-to-end within the platform.

API gateway to legacy systems

From initial discovery to ongoing support, Prime Horizon Technologies brings structure and care to software delivery. We translate business needs into maintainable applications designed to evolve.

Performance infrastructure

Elasticsearch handles search across the platform, while Redis manages caching. Together, they keep the system responsive as transaction volumes increase.
