Creation from scratch and maintenance of Canadian bank account taxation systems. This system is responsible for generating and providing users with all slips relating to taxes owed to the Canadian government. I'm responsible for creating microservices for each type of taxation, where we receive details of a client's account, their operations, movements, investments, and personal data, to generate slips data with the appropriate fees to be paid by the client to the government. Another part of this system is responsible for creating and providing the final slip document for the client through a REST API.These microservices are created using the NestJS framework, and their communication occurs through the gRPC protocol and Google PubSub. For each application, Docker is used to upload them to different environments on the Google Cloud Platform. All services have automated batteries of unit tests, component tests, and e2e using the jest framework.One notable achievement includes optimizing a critical microservice by significantly reducing database calls, resulting in enhanced overall service performance. Additionally, through a strategic refactoring initiative, I streamlined codebase complexity by consolidating and abstracting reusable components across this microservice, improving maintainability and efficiency.

I was responsible for developing banking applications for different clients. Development of backends following the hexagonal architecture to facilitate the integration of new customers into our system. Integration with external APIs to carry out financial operations such as account management, payments via bank slip, TED, DOC, pix, account statements, generation of income reports, and issuance and operations of physical and virtual credit cards, etc. The backend was created using Node.js, and TypeScript and for the unit and component tests, I used the jest framework. Development of mobile applications with different graphical interfaces, oriented to the clients' demands, using React Native. Creation of automated unit, integration, and end-to-end tests, to ensure the correctness of the systems. We had more than 5 different clients in parallel.

Responsible for developing low-code white-label solutions focused on customizable frontend applications using React and Nunjucks for different company clients. Usage of code optimizations to improve search engine work, achieving greater visibility and reach. Configuration of Google Analytics tags and functions to get insights and metrics from our client's users. Furthermore, I was responsible for creating backends within the SYDLE ONE tool to provide all the functionalities for our applications. This tool is based on JavaScript using MongoDB with ElasticSearch.

I developed the prototype of a virtual and augmented reality simulation framework. This project would be used by teachers from different courses to simulate environments and situations where it would be possible to have better visualization and interaction with examples that are closer to real scenarios.As a result, we obtained version 1.0 of the application, and we simulated a forest scenario for the Biology course, where we were inserted into this environment and it was possible to interact with the animals, plants, and objects in this scenario.
