As a Full Stack Developer for the largest bank in Latin America, using Microservices. I focus on the use of Angular and Webview that efficiently improve User Interfaces, the management of CI/CD pipelines with GitHub Actions, and leverage AWS S3 for effective storage and distribution. For Unit Testing, I use Jest; I use Cypress for e2e tests and I keep high-quality standards regarding Code Quality—ESLint, Husky, and Stylelint.Besides, I work on applications in C# for Webview Angular using Clean Architecture, Infrastructure as a Code with Terraform, Xunit for Unit tests, BDD with SpecFlow for Integration tests. Both applications use AWS and consume many services from the cloud, such as ECS, S3, ApiGateway Api 2.0, Lambdas (for authorizer), DynamoDB, Aurora, and EKS.On both apps, my competence in observability and analytics tools used for performance analysis and monitoring: are Dynatrace, AppDynamics, Google Analytics, Cloud Watch, Splunk, and Grafana.

I'm the tech leader of an innovation project using Blockchain Architecture, creating a private Ethereum network with Hyperledger Besu, using the combination of Truffle Framework and Solidity for managing Smart Contracts on this network. The project also uses Docker Engine, Keycloak, Minio, NestJs and Jest for unit tests and e2e tests, Angular Framework and Jasmine for unit tests, Cypress for e2e tests. This application is not provided on cloud, but is on promise. CI/CD Integrations using Jenkins, automation scripts, data scrapy using python to populate database for application using python integration with each resources (keycloak, the private ethereum network, databases)Soft skills: Management Dev Teams, creating and bettering the dev processing in Scrum, for instance: Pipelines (Jenkins & Bitbucket), Code Review, Automation processes, Planning Sprints, Full knowledge in business and help the dev team with it.
