Deanta - Software Engineer
PresentAt Deanta, I collaborate with a diverse, international team to develop and enhance the Deanta product. My role involves implementing new features, fixing bugs, and improving the user experience across our custom text editor and project management pages. I work with a wide range of technologies, including TypeScript, React, React Hook Form, and React Window (to optimize performance for long lists), among others. Additionally, I implemented linting and formatting, along with automation using GitHub Actions, to enhance our efficiency and maintain consistency across the codebase.

Notus - Software Engineer
At Notus, I worked as a Front-end Web Developer, where I was responsible for building high-quality, user-friendly, and visually appealing websites and web applications. Collaborating closely with designers, back-end developers, and product owners. I leveraged my expertise in HTML, CSS, JavaScript, and primarily React to develop dynamic, interactive user interfaces, always prioritizing clean, maintainable, and scalable code. I showcased my problem-solving abilities by troubleshooting technical issues and continually optimizing website functionality and performance. Throughout the development process, I actively contributed creative solutions and suggestions to enhance the overall user experience. Additionally, working with React Native and other technologies, I actively contributed to the development of Chainless, a Brazilian self-custody wallet for interacting with multiple blockchains. I was involved in creating essential screens for the user verification (KYC) and authentication flows, among other key features and performance improvements.
