What I'm looking for

I am looking for opportunities that allow me to innovate and grow in a collaborative remote environment.

I'm a Senior Front-end Developer with over 10 years of experience, all in remote work, specializing in crafting high-performance user interfaces with a strong focus on user experience. My expertise in JavaScript, React, CSS, and Next.js has been demonstrated through impactful projects at scale. I thrive in remote environments, honing my ability to work autonomously while maintaining excellent asynchronous communication.

In my most recent role at CloudWalk Technology, I led the complete restructuring of the online payment system for a fintech valued at over $1 billion. This project involved unifying two systems into a monorepo and integrating a complex payment system, enhancing security and development velocity. My previous experience includes developing an HTML and JavaScript application for Brazil's largest streaming platform, where I optimized performance for low-end devices, ensuring a seamless user experience across varying hardware specifications.

I am currently seeking new challenges in an international and remote environment, where I can leverage my expertise and passion for web development to contribute to innovative projects.
