Cloud-Based Retail Management SaaS Platform

Enhanced Rewaa's cloud-based retail SaaS platform with UI modernization, security layer implementation, and automated test coverage — strengthening the AWS-hosted platform for growing enterprise retail adoption.

Company Context

A SaaS company providing cloud-based retail management solutions to businesses managing inventory, sales, and multi-channel operations. Built on AWS, the platform serves growing retail businesses that need scalable operational management without enterprise-grade IT overhead.

What Our Scale Partnership Revealed

The platform UI had accumulated usability debt — components built at different times had inconsistent patterns, and adding new features required working around existing component limitations.
Application security needed strengthening — input validation, secure data handling patterns, and protection against common frontend vulnerabilities were insufficient for a platform handling sensitive retail business data.
Automated test coverage was sparse — each release carried significant defect risk because business logic wasn't covered by tests.

Engineering Work

Built new Angular UI components with consistent patterns — improved usability for retail operators and a cleaner foundation for future feature development.
Implemented enhanced security logic across both the Angular frontend and Node.js backend — input validation, secure data handling, protection against injection and XSS patterns.
Built automated unit test coverage for core business logic — the critical paths through the platform are now tested, reducing regression risk with each release.

System Outcome

UI modernized — retail operators work with a more consistent, usable interface.
Security posture strengthened — platform handles sensitive retail data with appropriate protections.
Unit test coverage in place — release confidence improved, defect risk reduced.
AWS infrastructure positioned for AI-driven retail analytics expansion.

Engineering Breakdown+

Security Implementation: Implemented Content Security Policy headers at the Node.js layer. Added input sanitization using DOMPurify on the Angular side for any user-generated content rendered as HTML. Implemented parameterized queries and input validation on all Node.js API endpoints accepting user data.

Test Coverage Strategy: Focused unit test coverage on business logic services rather than component rendering — the highest-risk code paths are the inventory calculation, pricing, and order processing logic. Jest for the Angular service layer, with mocked API dependencies to keep tests fast and isolated.
