What I'm looking for

I’m looking for opportunities where product ownership and engineering judgment carry equal weight.

At Nike, I owned an OpenSearch platform with infrastructure as code and deployment workflows, serving three independent systems and tens of thousands of READMEs, docs, and API specs. A text-embedding model powered its KNN search.

I co-led the migration of Nike’s developer portal to a self-hosted Backstage instance on Kubernetes, serving 3,000–5,000+ engineers across North America and EMEA. I also co-built its GraphQL layer with AWS AppSync and the Node Apollo client, and owned the Tech Radar plugin from customer outreach through delivery.

Before Nike, I helped evolve InComm Digital Solutions’ legacy monolith into a gift card and stored-value platform, and co-built a customer portal with Angular and C#/.NET MVC. At RMLS, I developed C# and Selenium WebDriver test frameworks and enhanced business applications; I’m looking for opportunities where product ownership and engineering judgment carry equal weight.
