Overview

Reusable APIs, event-based integration, containers, DevSecOps automation, and security controls modernized selected applications without replacing every core system.

01

Business Challenge

Older application components, point-to-point integrations, batch dependencies, and manual releases increased support effort and slowed change.

The credit union needed newer digital services to connect with core banking systems without adding complexity.

Solution Approach

A structured path from challenge to delivery

  1. Assess before replacing

    Map applications, databases, interfaces, middleware, batch jobs, and dependencies into retain, rehost, replatform, refactor, replace, or retire paths.

  2. Create reusable connections

    Introduce reusable APIs and event-based integration for selected member, account, payment, loan, authentication, and notification functions.

  3. Automate secure delivery

    Use containers, automated build and testing, security checks, deployment, monitoring, and appropriate identity and data controls.
