Background

About Jennysson Junior

I was the lead architect in developing the microservices infrastructure, from implementing Kubernetes on AWS's EKS to creating software development standards deployed throughout the company. I designed CI/CD pipeline flows, automating software validations and deliveries using GitHub Actions, and also developed several microservices from scratch, enabling systems to achieve the required performance aligned with the company's growth. I led the creation of a developer portal based on backstage where I also contributed to open source software through plugins. I conducted various training sessions for developers in different areas, helping a range of individuals advance in their careers. I have experience in developing applications using Node.js and REST APIs, integrating them with AWS services like S3 for data storage. Additionally, I implemented data streaming solutions using Kafka to ensure efficient communication between microservices. I am highly skilled in non-relational databases, using MongoDB for data management, and also utilized Redis for cache implementation. I performed automated testing using Jest to ensure code quality. I used monitoring tools such as Grafana, Prometheus, and New Relic to ensure system observability, collecting metrics and monitoring performance in real-time. Through my DevOps experience, I also implemented container orchestration solutions using Rancher, ensuring a highly scalable and resilient infrastructure.
