I'm a Senior Front-End Engineer with more than 10 years of experience building scalable, high-performance, business-driven web and mobile applications. I work on building high-quality digital products, defining architectures, technical standards, and engineering solutions that balance performance, user experience, and strategic goals.

Specialized in React, Next.js, TypeScript, React Native, and Flutter, I have solid experience developing modern platforms, Design Systems, scalable applications, API integration, back-end, cloud computing, and Artificial Intelligence applied to software development.

Throughout my career, I've contributed to the evolution of digital products through strong engineering practices, well-grounded architectural decisions, and collaboration with cross-functional teams. I believe technology excellence goes beyond code: it turns ideas into sustainable, efficient solutions capable of creating real impact for users and businesses.
