Message

At AT&T Service, Inc., I architected and developed Journey360, an operations triage and order lifecycle platform for Wireless, Wireline, and Broadband. I built its multi-mode search across eight sub-lines of business and its interactive order milestone and SLA dashboards.

Across telecom, healthcare, and lending systems, I’ve developed Java and Spring Boot services, full-stack applications, and event-driven platforms. At Amdocs, I built Flow Free, an automated diagnostics and remediation platform; at Salem Associates, I architected and developed LAPS, a loan origination and processing product.
