Senior Frontend Engineer
Senior Frontend Engineer with 10 years of experience building scalable web and mobile applications, with a strong focus on React, TypeScript, and React Native.
My core strength is frontend engineering—building performant, maintainable user experiences and designing architectures that scale. I enjoy turning complex product requirements into clean technical solutions, improving developer experience, and raising the overall quality of the systems I work on.
While frontend is where I shine most, I’m also comfortable working across the stack with Node.js and have experience building distributed systems and cloud-based applications on AWS.
I’m known for strong ownership, fast execution, and collaborative problem-solving. I enjoy working closely with product and engineering teams, mentoring other developers, and helping drive technical decisions that balance short-term delivery with long-term maintainability.
Fluent in Portuguese, English, and French. Always open to interesting conversations and great engineering challenges.
