Overview
Keyhole Software partnered with a major supply chain organization to modernize a critical internal user interface. The engagement focused on replacing a rigid legacy delivery system with a dynamic, form-driven React application. This effort served as a proof of concept and foundation for broader modernization across internal systems.
Challenge
- Legacy UI components were difficult to scale, modify, and maintain.
- Business rules were tightly coupled and hardcoded, reducing flexibility.
- The client needed to validate a scalable front-end architecture for future projects.
- Internal teams lacked exposure to modern development practices.
Our Approach
Keyhole delivered a modern single-page application built with React 19 and TypeScript, emphasizing reusability, accessibility, and maintainability.
Key Implementations:
- Schema-Driven Forms: Used Zod and JSON configs to dynamically manage form logic, reducing code duplication and simplifying updates.
- Custom Component Library: Extended Material UI to create consistent, branded, and accessible components.
- Monorepo Architecture: Adopted NX and Vite to improve modularity, build performance, and team collaboration.
- Comprehensive Testing: Integrated Jest and Playwright for full test coverage—unit, integration, and end-to-end.
- Role-Based Access Control: Applied at the route, page, and field level for granular permission handling.
- Agile Delivery: Held bi-weekly demos for real-time feedback and rapid iteration.
- Developer Enablement: Provided informal mentoring to internal developers to build confidence in modern front-end practices.
Impact
The result was a production-ready React application that not only met the client’s immediate needs but also successfully validated a new architectural approach for future front-end initiatives. The use of schema-driven forms and modular design patterns significantly improved maintainability and positioned the client for more efficient scaling. Agile delivery practices, including frequent stakeholder collaboration, led to faster feedback cycles and improved alignment across teams. Just as importantly, the client’s internal developers were empowered through hands-on exposure to modern tools and best practices, allowing them to confidently carry the front-end modernization forward.
This engagement left a lasting impact by transforming both the technical foundation and the development culture. It equipped the client with a scalable, maintainable front-end solution while building internal confidence and capability for continued modernization.
