Pharmacy Inventory App

ARxIS: Walgreens Specialty Pharmacy Inventory Management System

Rebuilding Inventory Infrastructure for a Regulated Supply Chain

MY ROLE

Sole Design Ownership

Systems Thinking

UX UI Design

To comply with the FDA’s Drug Supply Chain Security Act (DSCSA), I redesigned a 20+ year-old, analog inventory system into a modern mobile experience.

Overview

Turning Operational Complexity into Guided Mobile Workflows

To comply with the FDA’s Drug Supply Chain Security Act (DSCSA), I redesigned a 20+ year-old, analog inventory system into a modern mobile experience—enabling real-time inventory visibility and tracking, improved accuracy, and and regulatory alignment across the pharmaceutical supply chain to ensure safer pharmaceutical distribution at scale.

As the sole designer on a lean, high-impact team, I operated beyond UI—partnering deeply with engineering to translate complex regulatory and operational requirements into a cohesive, scalable system. The result is an interoperable, package-level tracking experience that reduces risk, improves accuracy, and supports rapid identification and removal of unsafe drugs.

Key Impact

Improving Efficiency, Accuracy and Traceability Real-Time

The new app enhances critical warehouse workflows while introducing net-new capabilities required for DSCSA compliance. It supports an interoperable, package-level tracking system that helps identify and remove unsafe drugs quickly—ultimately protecting patients and ensuring supply chain integrity.

Brought a legacy system into compliance with DSCSA, aligning with FDA mandates for traceability and safety
Reduced operational friction by modernizing slow, manual workflows into guided, mobile-first experiences
Designed for real-world operator use, enabling faster task completion and higher accuracy
Introduced system-level validations and guardrails to reduce errors and ensure compliance
Established a scalable UX foundation that can evolve alongside regulatory and operational changes

Note: This project is ongoing and we are still gathering impact data.

“I’m moving a lot faster through tasks because I’m not stopping to think about the next step—it’s just right there.”

“Receiving new inventory used to take forever because I had to scan every item. Now I just scanning is faster and more accurate."

“It didn’t take long to get used to. Once you do it a couple times, it just makes sense.”

“The old system was slow and kind of clunky. This is just… easier. Especially when you’re busy and trying to get through a lot quickly.”

Approach

Quick action, close collaboration, & in-flight testing

We worked in a highly iterative, agile model—designing in tandem with live operations. By pairing closely with engineering and grounding decisions in real user behavior, I was able to go deeper than surface-level UX—shaping the underlying system logic and ensuring the experience held up across real-world complexity.

Applied systems thinking to translate deep, complex backend logic into intuitive, operator-friendly workflows
Leveraged a strong understanding of engineering constraints to design solutions that were both elegant and feasible
Close partnerships with:
- A lead engineer (30+ years experience) with deep operational and information architecture expertise of Walgreens-specific fulfillment operations
- A skilled contract Full Stack engineer who moved quickly from building back-end logic to high-quality UI implementation
- A business analyst embedded in micro-fulfillment centers, providing real-time user feedback and validation

This tight collaboration allowed us to move with speed and precision—making informed decisions without heavy process overhead.

Core Features

Receiving Reimagined intake workflows with real-time validation and traceability at the package level
Putaway Designed guided placement logic across standard storage and quarantine states, improving efficiency by organizing the operator’s route on the backend after Receiving was completed
Intracompany Transfer (ICT) Enabled seamless, trackable movement of inventory between distribution centers
Quarantine Introduced clear system states and controls for isolating and managing at-risk inventory

Summary

Turned a legacy system into a scalable foundation for real-time inventory integrity

This project modernized a mission-critical inventory system at the core of a regulated pharmaceutical supply chain. By translating complex DSCSA requirements, we turned deeply complex operational logic with intuitive, mobile-first workflows used in fast-paced warehouse environments. Working in close partnership with engineering and frontline operations allowed me to continuously iterate alongside real operational behavior, as system logic and user needs evolved.
