I've built scalable e-commerce and enterprise web platforms for Scale Media, Appetize, and Dun & Bradstreet. My work spans PHP, JavaScript, Golang, React, and cloud-native microservices.

At Scale Media, I independently developed a React content management system for customer service representatives and an A/B testing dashboard to support conversion and subscription sales. I also launched five Shopify storefronts and built reusable branded components.

At Appetize, I modernized legacy PHP systems into Go APIs and microservices, improving a large-inventory API's performance by 50% from seconds to milliseconds. I enjoy delivering reliable, high-performance applications that make complex workflows easier for teams and customers.
