My professional journey boasts a record of data-driven solutions, fixes, and optimizations to resolve critical issues and develop new and improved applications and features. My work for major technology ecommerce organizations has encompassed major data migrations, syncing, and integration, user interface systems, and other internal as well as customer-facing applications and optimizations. Some examples of my contributions include fixing a critical security vulnerability in advance of a merger, gathering requirements and defining technical specs to drive an ERP integration, and porting a legacy ecommerce website to run on the cloud platform Heroku.

In my most recent role as a senior backend engineer with DocGo, I led the development of a service which integrated the organization’s databases with the CRM and the contact center software, which reduced the cost per 550 bookings from $1,008 to $112 and increased average weekly calls from 3,000 to 30,000.
