At T-Mobile, I owned development and modernization of a retail-facing Angular application used across 70K+ POS terminals serving 21M+ active subscribers. I built payments, privacy, authentication, and support capabilities spanning customer and retail operations.
I pioneered GraphQL adoption for COPPA compliance, powering privacy dashboards and eliminating approximately $250K per week in compliance-related costs. I also led a zero-downtime migration of REST endpoints from Okta to Microsoft Entra and implemented PC-based 2FA for manager overrides.
I integrated EMV contactless payments through a custom Node.js wrapper, supporting 250K+ weekly transactions and reducing payment processing failures by about 38%. I also built Quick Payments, increasing prepaid revenue by roughly 18%, and Fastify APIs that improved support ticket resolution efficiency by more than 50%.
Previously, I modernized Macy's retail web experiences from Backbone/Marionette to Vue.js and built microservice-based enterprise applications at AT&T. Across my work, I use TypeScript, JavaScript, Angular, React, Java, Spring Boot, Node.js, Python, and cloud-native delivery practices to ship reliable systems.
