• Restructured a mission-critical analytics page that displayed multiple charts based on hundreds of thousands of IoT sensor readings, with a strong focus on performance optimization. Leveraged techniques such as binary-search algorithms, memoization, and virtualization, reducing page load time by 80% and significantly minimizing UI freezing on low-performance machines. • Collaborated directly with the Machine Learning team to develop a feature that enabled users to retrain their vibration sensors using intervals identified as "healthy operation periods." This solution eliminated the need for back-office intervention and reduced support tickets related to the process to zero.

• Maintained the design system used by the company, in addition to creating new components with a focus on accessibility and usability. Handled versioning and publication on npm, created documentation through stories on Storybook, and performed unit and accessibility tests. These changes were crucial for improving developer experience and integrating with the design team. • Implemented applications monitoring through events emitted by Amplitude and Google Analytics 4, generating relevant data for strategic decision-making about many products. • Contributed to the development of many critical features related to the Brazilian financial system, such as loans, bank transfers, invoices, cash flow, among others. • Led the implementation of server components architecture, resulting from two major package version updates, namely ReactJS (from 17 to 18) and Next.js (from 12 to 13), adapting projects and assisting developers in understanding the newly adopted paradigm.

I taught classes in the Gama Experience program at Gama Academy, a bootcamp company, focusing on technologies within the ReactJS ecosystem. Besides React itself, I covered topics such as TypeScript, Styled-components, Redux, automated testing, accessibility, front-end application performance optimization, and advanced CSS techniques.

• Led the front-end development team, providing technical guidance, making decisions regarding the stack used in each project, documenting through ADR writing and directly reporting results to the company stakeholders. • Collaborated in creating a GPS-based cattle monitoring system, as well as a back-office tool used by company employees. Technologies utilized included Next.js, TypeScript and Tailwind. Authentication implementation using Keycloak. • Created a culture of writing automated tests on the front-end applications, using Jest and React Testing Library, thereby enhancing security in the deployment process. Besides that, I made presentations to guide other developers in writing their tests.

• Participated in the development of the company's flagship product, a marketplace that connects service sellers and buyers, built with ReactJS, Next.js and TypeScript. • Integrated the product with Vonage's video call API, enabling two clients to communicate through the platform with video, audio, chat, and file upload functionalities, with this tool being the core of the company's primary income.
