Building front-end systems for complex, high-impact applications

I'm a Senior Front-End Engineer with experience building payment systems, regulated medical software, and civic technology. My work emphasizes accessible interfaces, reliable systems, and reusable front-end architecture.

I'm currently interested in senior front-end and front-end platform roles where I can remain hands-on while helping teams improve architecture, accessibility, testing, and delivery.

Led front-end development for Walmart.com payment experiences including EBT SNAP, WIC, PayPal, Affirm, and credit cards.

Regulated Scientific and Medical Software

Built laboratory and medical-imaging applications for regulated and clinically complex environments.

Accessibility at Scale

Developed reusable architecture, accessibility tooling, testing practices, and production safeguards used across teams.

Selected Work

A closer look at projects where I shaped the front-end architecture, solved hard problems, and delivered systems people depend on.

Unifying Payment UI Across Walmart.com
Walmart Global Tech · Staff Front-End Software Engineer · 2019 — 2024
I designed and built a reusable React Wallet component that replaced separate payment form implementations across Walmart.com purchase flows. The shared system made payment behavior more consistent and reduced the effort required to support new payment methods in a high-volume, PCI-regulated environment.

Bringing WIC Benefits Online
Walmart Global Tech · Staff Front-End Software Engineer · 2019 — 2024
I led the front-end integration that enabled WIC participants to use eligible benefits in Walmart's online grocery checkout. The work combined a regulated payment flow, item-level eligibility, and split tender within an existing checkout system while maintaining clear and accessible customer guidance.

Dual Imaging for the Sequoia Ultrasound Platform
Siemens Medical Solutions (Acuson) · Senior Software Engineer · 5 years
The Siemens Sequoia was a high-end diagnostic ultrasound system used in cardiology, radiology, and obstetrics. Clinicians needed the ability to view two imaging modes simultaneously — for example, a real-time 2D image alongside a Doppler waveform — to make faster, more informed diagnostic decisions without switching between views.
