## About

```text
At Pinterest, I architected and implemented a React and TypeScript micro-frontend structure for modularity, maintainability, and independent deployments. I also led a testing initiative that raised coverage from 40% to over 70%.

At Jusbrasil, I optimized Web Vitals through lazy loading, code splitting, and memoization, improving page load time (LCP) by 22%. Across my work, I’ve built responsive web and mobile applications, integrated APIs, and mentored less experienced developers.
