About

I'm a senior full stack engineer based in Frederick, CO with over a decade of experience building scalable, maintainable applications. My expertise spans the full stack — from React and React Native frontends to Node.js microservices and AWS cloud architecture.

I specialize in serverless technologies and have deep experience with AWS services including Lambda, Step Functions, AppRunner, Cognito, RDS, and DynamoDB. I'm passionate about TypeScript and have championed its adoption across every team I've worked with to improve code quality and reduce runtime errors.

I hold a BS in Computer Science from Colorado State University (2014). When I'm not coding, I enjoy working on my latest app ideas, exploring new technologies, and building things that make a difference for local businesses.
