## About

```text
I'm building and maintaining Kasta’s cryptocurrency trading platform with Next.js, React, Redux, GraphQL, and AWS Lambda. I also improve reliability and product monitoring through automated testing, Datadog, Sentry, Firebase, and Mixpanel.

At Zup Innovation, I delivered web and mobile financial applications and contributed to Itaú’s AI chatbot training platform and legacy modernization. I helped evolve Micro-Frontend architecture, Design Systems, Clean Architecture foundations, and shared business rules across Next.js and React Native.

Previously, I supported frontend architecture and technical standards at PicPay, built transportation and manufacturing products at Ambev Tech, and developed management systems with PHP, Laravel, React, and Vue.js. I’ve also taught graduate-level frontend courses covering React, Angular, and Vue.js.
