Cost Card

Overview

Azure customers were abandoning VM provisioning flows due to cost uncertainty β€” they couldn't see pricing until after configuration. I led the design and development of the Cost Card, a real-time pricing component that dynamically calculates and displays estimated costs as users configure their virtual machines.

The solution required building a performant React component that consumes Azure's pricing APIs, handles complex configuration permutations (region, VM size, OS, storage), and renders instant estimates without blocking the UI. I architected the component using Fluent UI, integrated it into Azure Portal's micro-frontend ecosystem, and collaborated with PMs and designers to iterate on the UX.

virtuwell

Overview

virtuwell is a 24/7 online clinic serving thousands of patients daily across 50+ conditions. The legacy platform had accessibility gaps, inconsistent UI patterns, and a fragmented patient journey that led to high drop-off rates during intake.

I led the frontend modernization effort, rebuilding the patient-facing experience with an accessibility-first approach. This included creating a reusable component library, implementing WCAG 2.1 AA compliance across all flows, redesigning the multi-step intake wizard for clarity, and optimizing performance for mobile-first users. The result was a dramatically improved patient experience with measurable gains in completion rates and satisfaction scores.

Pricing Calculator

Overview

The Azure Pricing Calculator needed a Fluent UI modernization, but stakeholders estimated months of work for a full migration. I challenged that assumption by building a functional proof-of-concept in approximately 3 hours.

The POC demonstrated that incremental migration was feasible β€” we could modernize components progressively without rewriting the entire application. I implemented key UI components in Fluent UI, showed seamless integration with the existing codebase, and presented the results to leadership. This shifted the conversation from "if" to "how," unlocking a faster path to modernization and influencing the team's technical roadmap.
