Senior Front-End Engineer at S&P Global who migrated 30+ Capital IQ Pro pages to micro frontends.

At S&P Global, I developed and scaled React and TypeScript features for S&P Capital IQ Pro, a financial intelligence platform for complex, data-intensive applications. I migrated over 30 pages from a legacy XML architecture to micro frontend services, improving page load times by 1–3 seconds.

At S&P Global, I also managed three developers and established frontend styling standards using Emotion CSS and LESS. Earlier, at Zimmerman Advertising Agency, I developed responsive websites and landing pages for brands including Advance America, Sam's Club, and Jamba Juice.
