The Challenge
A core system that couldn't keep up
The client’s lending platform built over twelve years as a single monolithic application had become the biggest brake on the business.
Every release was slow and risky, scaling for peak demand was painful, and the architecture simply couldn’t support the AI and integration capabilities their roadmap demanded. A full rewrite felt too risky to attempt.
No digital presence
Window displays relied entirely on printed paper costly, error-prone, and impossible to update without a physical visit to every location.
Connectivity had to be bulletproof
Displays needed to stay online under all conditions; uneven 4G coverage demanded a dual-stack failover architecture with local offline caching.
Manual content updates were costly
Staff spent hours printing and physically placing flyers, with any content change requiring a visit to every display location.
No cloud-to-screen integration existed
No available tool could sync cloud content directly to physical window displays — content was always lagging behind reality.
End users were entirely non-technical
The full workflow had to work via drag-and-drop with a near-zero learning curve.
The Solution
A phased, zero-downtime
transformation
The client’s lending platform built over twelve years as a single monolithic application had become the biggest
brake on the business.
Every release was slow and risky, scaling for peak demand was painful, and the architecture simply couldn’t support the
AI and integration capabilities their roadmap demanded. A full rewrite felt too risky to attempt.
Cloud SaaS dashboard
Delivered a zero-install, browser-based dashboard with real-time content push, drag-and-drop media scheduling, role-based access, and custom brand templates per client.
IoT & connectivity layer
Engineered embedded 4G SIM and Wi-Fi auto-failover hardware that always switches to the strongest signal, with offline content caching so displays are never blank plus remote firmware OTA updates.
Platform integration engine
Built a content engine compatible with all major sources, auto-transforming content to each display's layout with seconds-level delivery and zero manual re-entry.
