About

Professional summary

I am a customer-obsessed systems engineering professional with 10 years of experience spanning frontline service, enterprise operations, technical support, and systems analysis. I combine an understanding of customer-facing business needs with the technical skills to improve the systems behind them.

At Verizon, I progressed from technical support and systems coaching into global enterprise operations, IoT and API systems, and Engineer III systems analysis. I have owned enterprise platform operations, led critical escalations, designed workflows, and delivered integrations for large-scale device lifecycle management.

I independently led a digital transformation initiative, delivering 69 of 85 Jira stories in less than 30 days against an eight-month forecast. My work includes cross-platform entitlement architecture, high-risk transaction approval workflows, production releases, regression testing, and performance validation.

I am also an accessibility advocate and was named Verizon's company-wide JAWS Accessibility Subject Matter Expert. I created enterprise accessibility training used by leadership and bring experience with Section 508, process automation, Agile delivery, SQL reporting, Salesforce, Google Cloud Platform, and Teradata.

Before technology, I developed strong operational and leadership foundations in grocery, restaurant, and small-business environments. I have managed inventory, vendors, customer escalations, cash handling, training, scheduling, and client relationships, giving me a practical perspective on business operations and customer experience.
