Creating unique digital products.

React JS, Next JS, React Native, Firebase, Contentful, SEO, GraphQL, Relay

• Coinbase is a secure online platform for buying, selling, transferring, and storing cryptocurrency. As a software engineer at Coinbase, I have been responsible for designing and developing complex web and mobile applications. Among my contributions, I:
• Learned how software engineering works at a big tech company.
• Coded multiple experiments in the Coinbase app and managed them to pick the correct variant that increased users and trades.
• Developed the new How To Buy page, a project that uses Contentful as the CMS and SEO best practices to teach the user how to buy an asset when searching at Google(e.g.: search for "how to buy Solana").
• Integrated the How To Buy project with Google's How-To Structured Content to improve user interaction and page ranking SEO.

React Native, Next JS, Firebase, CI/CD

• Tembici is the biggest micro-mobility company in Latin America, users can rent a bike in multiple stations in Brazil, Argentina, Chile, and Colômbia. As a Software Developer at Tembici, I was responsible for re-writing the mobile app using React Native to ensure that one codebase could generate not only an Android and iOS app, but 3 different app variants(Tembici, Bike Itau, and BA Ecobici). Among my contributions, I:
• Led the code improvement process, using SOLID and Design Patterns, to separate the project into layers and decouple the UI from the business rules.
• Led the project's documentation and standardization process, developing a technical guide for the modules and contributing with Design Docs.
• Led the process of creating automated tests, by documenting how to test in React Native with Jest and Testing Library and pairing with my partners.
• Migrated all the animations for Reanimated v2, due to the crash rate. And implemented new complex animations.
• Integrated the project with the Firebase tooling, such as Events, Crashlytics, Remote Config(for feature flags), and Dynamic Links(for deep links).

Next JS, Chakra UI, Node JS, Figma

• MBDA Digital Assets is a company from the group Mercado Bitcoin, the biggest crypto exchange in Latin America. As a Front-end Developer in MBDA Digital Assets I was responsible for designing and implementing a website that helps users understand all the security and market behind a crypto token. Among my contributions, I:
• Participated in several workshops, taught by members of the Mercado Bitcoin, to learn about Blockchain, Solidity, and the Ethereum network.
• Developed the MBDA Explorer prototype, a tool that aims to democratize the understanding of asset tokenization, interacting with the Ethereum network and showing data about tokens in a clear and intuitive way.
• Developed MBDA Explorer using Next JS, Chakra UI, Docker, and docker-compose. With this stack, it was possible to guarantee delivery speed, code quality, and a good UX.

React JS, Angular JS, Figma

• Participated in the Gov.br digitization process, having to apply its design system in a legacy pricing tool for the Ministry of Economy.
• Identified UX issues that the legacy tool had, then I created a prototype for a new version and applied usability tests to validate it.
• Rewrote the tool's front-end, using React JS, and applied SOLID and Design Patterns to generate faster cleaner and more maintainable code.

React Native, Redux, Firebase

• Rocket. Chat is a customizable open-source communications platform for organizations. It enables real-time conversations between colleagues, with other companies or with your customers, across devices on web, desktop or mobile.
• I was selected from hundreds of global candidates to participate in the Google Summer of Code program. The project was to add Firebase Analytics to Rocket Chat's React Native app.
• Registered all the app's features through events. With this data, we were able to improve observability and quantify the feature usage.
• Created funnels to analyze the completion rate for some screen flows, getting usability and interest metrics for the tested features.

Vanilla JS, React JS, React Native, Firebase, Figma

• Developed several projects from the beginning, creating their visual identities, prototypes, and coding websites and apps using React JS, React Native, and Firebase.
• Improved the team's productivity by applying agile development practices, such as sprint planning, pairing, code-review, automated testing, and gitflow.
