Work Background

SRE / DevOps

NTT DATA Europe & LATAMSRE / DevOps

Nov. 2021Uberlândia, Minas Gerais, BrasilImplementei e gerenciei infraestruturas escaláveis na AWS utilizando Terraform, garantindo alta disponibilidade e monitoramento eficiente com CloudWatch. Desenvolvi aplicações robustas em Python, .NET Framework, Java e Spring Boot, integrando serviços da AWS como SQS e SNS. Automatizei processos com scripts Shell e GitHub Actions, otimizando o fluxo de trabalho e a entrega contínua (CI/CD). Utilizei Git para versionamento de código e colaboração em equipe, e GitOps para gerenciar a infraestrutura como código. Implementei e gerenciei clusters Kubernetes para orquestração de containers, garantindo escalabilidade e resiliência. Monitorei e analisei logs em tempo real com o Splunk, identificando e solucionando problemas de forma proativa. Construí pipelines de CI/CD eficientes com GitHub Actions, automatizando testes, builds e deployments. Acessei e manipulei dados em diversos bancos de dados. Utilizei o Jaeger para rastreamento distribuído em microsserviços, facilitando a identificação de gargalos e otimizando o desempenho.
