• Developed the front-end for an internal blockchain tracing tool, that helps the compliance team investigate suspicious transactions and wallets with graphing capability.

• Coded multiple GraphQL resolvers and migrated back-end monolith rails code to Golang services to meet the company goal for better latency and back-end scaling.

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 features. Among my contributions, I:

• Coded multiple country-based A/B experiments in the Coinbase app splash screen to increase user engagement before signup, and handle different regulations, such as the new Logged Out App token browse.

• Coded multiple incentive-based A/B experiments in Coinbase app signup and managed them to pick the correct variant that increased users and trades.

• Developed the new How To Buy page, a dynamic Contentful driven page with 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.

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:

• Coded multiple impactful and complex features such as map interactions, trip timer, trip review, feature flag system, deeplink system, and an internal notification system connected with AppsFlyer.

• Led the process to create automated tests by documenting and code pairing with my teammates, and improved the codebase quality by applying SOLID and DDD to decouple the UI from the services.

• Led the project's documentation and standardization process, developing a technical guide for the modules and contributing with Design Docs.

• Integrated the project with the Firebase tooling, such as Events, Crashlytics, Remote Config(for feature flags), and Dynamic Links(for deep links).

• Migrated all the animations to Reanimated v2, due to the high crash rate, and implemented new complex animations.

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.

• 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.
