};I'm a Fullstack Developer with 5+ years of experience across backend, mobile, and frontend development. I've worked at small startups building products from scratch, as well as large global companies like Globo and Mastercard.
I have strong experience building REST APIs with TypeScript, Node.js, Kotlin, and Java/Spring, shipping mobile apps with Flutter, and delivering frontend solutions with React and Next.js. I've also led engineering teams and collaborated closely with product and design.
People often describe me as communicative, creative, and curious. I love building new products and solving real problems.
