What I'm looking for

I'm looking to build and modernize secure, maintainable back-end applications, APIs, databases, and cloud integrations in a collaborative, mission-critical environment.

At Deloitte, I modernize and support business-critical C#/.NET applications and data services across legacy and cloud environments. I built a GraphQL integration layer in Azure that consolidated up to 23 downstream data-source calls into one transaction and reduced query execution time by 85% through legacy modernization.

I also create automated regression coverage, troubleshoot application and database failures, and deliver high-volume Oracle workflows in AWS RDS. My migration work moved more than 3 TB across 26 schemas, 255 tables, and approximately 75 million records using controlled validation and reconciliation processes.

Previously, I led the full lifecycle of 20+ enterprise applications for the Minnesota Army National Guard, supporting approximately 10,000 soldiers. I bring secure development, production support, database design, Agile delivery, and technical leadership from regulated, mission-critical environments.
