1. The Challenge
An Ontario-based pharmaceutical waste facility was bottlenecked by an undocumented legacy supply chain application. The system relied heavily on unwritten operational knowledge and a fragmented "independent dialog box" UI pattern. Furthermore, because it lacked an administrative frontend, minor data corrections required backend engineers to manually execute database changes via Jira tickets. This created severe operational delays and misused costly engineering resources.
The business and legal stakes were critical:
Strict Compliance: Under Health Canada regulations, the facility faced a strict 10-day mandate to process incoming hazardous shipments.
Revenue Risk: Any system instability or manual data-entry error directly threatened federal compliance, risking the immediate shutdown of active revenue streams.
The Impact
Centralized System Architecture: Partnered with a Business Analyst and engineering triad to overhaul the information architecture. Replaced disjointed dialog boxes with centralized, task-based workflows aligned directly to backend database realities.
Accelerated Product Delivery to 2 Weeks: Navigated a major mid-project strategic pivot by establishing a rapid design-to-development loop utilizing a component library (Shadcn UI), significantly compressing the launch timeline while maintaining cross-functional alignment.
Optimized Field Usability via Data: Used AI to transform technical system messages into predictive notifications. Post-launch, analyzed warehouse-floor usage via Microsoft Clarity session replays to optimize touch-target sizes for fast-paced environments and refine real-time data refresh behaviors.
Reduced Operator Training Time: Replaced reliance on memorization with clear system states and contextual guardrails, allowing new warehouse operators to onboard faster with minimal data-entry errors.

The Process
1.
Foundation & Logic alignment
9 Months
Information Architecture: Replaced fragmented pop-ups and independent dialogs with centralized, task-based workflows.
Compliance Mapping: Embedded federal regulations and administrative rules directly into the underlying system logic, preparing the data structure for future scaling.
2.
Core Workflow redesign
6 Months
On-Site Research: Visited warehouses to analyze physical workflows firsthand, ensuring the digital interface mapped accurately to floor operations.
2-Week Sprint Loops: Restructured team collaboration to shorten design-to-development cycles to 2 weeks, accelerating engineering handoffs.
3.
UAT, Validation & Polish
4 Months
AI & Process Alignment: Integrated Claude into technical reviews to refine complex system logic and streamline cross-functional workflows.
Continuous Validation: Conducted a comprehensive UI audit and embedded a veteran warehouse power user directly into engineering sessions for immediate feedback.
On-Site Stress Testing: Ran daily 2-hour UAT sessions with operators to catch real-world usability bugs and finalize UI component states before deployment.
