Northbank Digital Banking Platform

Overview

Northbank needed one coherent product surface for accounts, payments, and support instead of four disconnected legacy tools. We rebuilt the front end as a server-rendered React platform with a shared design system and a hardened API layer.

The client's problem

Four separate legacy portals meant duplicated logins, inconsistent data, and a support team switching between systems on every call. Page loads averaged 6.8 seconds and mobile usage was effectively unusable.

Project goals

• Consolidate four portals into one product
• Cut time-to-interactive below two seconds
• Make the whole experience usable on mobile
• Give the internal team a design system they own

Challenges

• Strict financial compliance and audit requirements
• Zero-downtime migration of live customer sessions
• Legacy SOAP services with inconsistent contracts
• Accessibility conformance across 60+ screens

Our solution

We introduced a typed API gateway in front of the legacy services, rebuilt the client as a server-rendered React app, and shipped a documented component library. Migration ran feature-by-feature behind flags, so customers moved across without a single maintenance window.
