Utilized AWS services including DynamoDB, Lambda, SNS/SQS to design and manage scalable backend and contributed to the development of the product using TypeScript with the NestJS framework, ensuring code quality, maintainability, and adherence to best practices.

Provided insights and guidance on backend architecture, feature implementation, and integration with both frontend interfaces and third-party services.

Helped the transformation of the product, expanding its capabilities from a card project to a full-fledged banking platform offering US treasury investments, financial advisory services, check deposits, and more.

Actively collaborated troubleshooting issues, identifying optimization opportunities and continuous improvement.

Helped on the early stage of development of a reconciliation product. Even though I didn't stay there for long, I did my best to give architectural and development insights to achieve a good and performatic product at the end. The key stacks we used were Node.js, Postgres, Kafka and Docker.

During the inception of Open Brasil, led by the Brazilian Central Bank, Quanto aimed to create a product that could facilitate integration between a user's bank and Open Finance Data. I personally played a pivotal role in the early stages of the project, where I focused on reading and comprehending all necessary (and legal) documentation, providing insights into the solution we were building, refining its boundaries across teams and implementing the code.

Additionally, I served as a communication bridge between the frontend and backend teams, drawing upon my previous experience on doing this.

The technologies I utilized included Node.js, Kotlin, Spring, Docker, Postgres, Kafka, and gRPC.

I've had the opportunity to work on projects for a diverse range of companies, both national and international. My responsibilities extended from initial implementation to architectural design, providing insights to enhance the project outcomes.

Across these projects, the JavaScript ecosystem (Node.js and React), served as a cornerstone. Additionally, I used a variety of complementary tools and technologies, such as Docker, AWS, Kubernetes, and Kafka, changing their use according to the specific needs of each project.
