Atuando em diferentes iniciativas, em todo o ciclo de vida do software: desde levantamento de requisitos e arquitetura de solução até desenvolvimento, implantação e monitoramento.- Desenvolvimento de aplicações web para o usuário final, com foco em usabilidade e performance;- Contribuições na biblioteca do design system (inner source), implementando melhorias de usabilidade e acessibilidade;- Melhorias de segurança, mapeando vulnerabilidades e definindo novas arquiteturas em coordenação com diferentes áreas. Tecnologias: Angular, React, Java, Quarkus, Spring, MongoDB, HTML, CSS, TypeScript, Stencil

I work at Sicredi, developing, evolving and maintining systems that handle over 100,000 daily transactions.- Front-end development with Angular. Automated testing using Cypress, Jest and Testing Library.- Back-end development with Java in a microservices architecture, using Quarkus, Spring, MongoDB and JUnit. - System support in production environment, running root cause analysis, correcting defects and resolving incidents.- Requirement engineering in collaboration with business, CX and development professionals, mapping out improvements, fixes and technical debt. RESULTS- I led a comprehensive refactoring in the front-end of one of our BackOffices, substantially improving code quality and development experience. Thousands of duplicated lines of code were removed, and test coverage went from 0 to about 50% (from 40k LOC). This refactoring allowed for faster and higher-quality deliveries in the following work.- I helped in the implementation of automated testing culture among the development team, by setting up the test environment and creating documentation and examples that accelerated the learning curve for others.- I made structural changes to some REST endpoints, promoting ease of maintenance and performance improvements. In some of these endpoints, response times were reduced by more than 50%. - I resolved complex issues in a microservices architecture, participating in the entire development process: root cause analysis, solution design, implementation and validation.

I worked at the Finance Secretary of the state of Sergipe, developing front-end applications with Angular. - Front-end development with Angular, TypeScript, HTML and CSS.- Migration of legacy systems to a monorepo architecture, promoting code quality and reuse.- Implementation of automated tests with Cypress.RESULTS- I created dozens of highly reusable and well documented UI components and utility functions, accelerating the development of new functionality.- I stablished an automated testing culture in the team, creating their first automated tests with Cypress. - I promoted changes in the team's work methodology, both on the process and technological level, which converted to a direct impact in productivity. For example, through these changes, it was possible to substantially reduce the time spent solving Git conflicts.- I created JavaScript scripts to automate repetitive tasks.

I developed REST APIs with Node.js and Express, using both RDBMS nd NoSQL databases. I sought implementing high quality and well tested solutions. I created CI/CD pipelines with GitHub Actions. I also worked in the R&D department in an endeavor to elevate the development practices implemented in the company.Tools: JavaScript, Node.js, Express, Jest, MongoDB, PostgreSQL, Git, GitHub, Bitbucket

I volunteered on a community of around 10 thousand programmers from all over the world. Besides that, I worked actively in the development of a bot for the discord server. We used TypeScript and TDD.Tools: TypeScript, Discord.js, Mocha, Chai, Sinon, Git, GitHub

I reviewed the literature on multiview data clustering, implementing the proposed algorithms in C and C++. I compared the performance of those algorithms in different scenarios, using Python and Shell scripts to optimize my workflows. Tools: C, C++, Python, Shell, LaTeX, Git, GitHub
